DIAGNOSTICS OF TROUBLE CODES

Diagnostic Trouble Code (DTC) Type Definitions

Emissions related fault codes
- type A
The controller illuminates the Malfunction Indicator Lamp (MIL) when a malfunction is detected during diagnostics.
Action Taken When the DTC Sets - Type E
The controller turns on the Malfunction Indicator Lamp (MIL) during the next ignition cycle, at which a malfunction is detected a second time during the diagnostic process.
Conditions for Clearing the DTC/Turning Off the Malfunction Indication - Type A or Type E
1. The controller turns off the Malfunction Indicator Lamp (MIL) after 3 consecutive ignition cycles in which no fault is detected by diagnostics.
2. The current DTC "Last Check Failed" is cleared after the diagnosis is successful.
3. Using a scan tool, turn off the MIL and clear the DTC.

DTCs not related to the emission of harmful substances
Action Taken When the DTC Sets - Type C
1. The controller writes a fault code to memory when a fault is detected during the diagnostic process.
2. As soon as an error occurs, the Service Vehicle Soon (SVS) indicator will illuminate.
3. If the vehicle is equipped with a driver information center, a message may be displayed on the vehicle.
Conditions for Clearing DTCs - Type C
1. Faults found during the last previous diagnosis or active fault codes are cleared if no faults are found during the diagnosis.
2. Use a scan tool to clear the DTC.

Diagnostic Trouble Code (DTC) P0008 or P0009
DTC Description

DTC P0008: Bank 1 Engine Position System Performance

DTC P0009: Bank 2 Engine Position System Performance

Description of circuits / systems

The Engine Control Module (ECM) checks for mismatch between the positions of both camshafts in the same bank of cylinders and the crankshaft. Mismatch is possible either at the guide sprocket of each of the rows of cylinders, or at the crankshaft. Having determined the position of both camshafts of the engine cylinder bank, the ECM compares the obtained values ​​​​with the control ones. The ECM will set a DTC if both determined values ​​for one engine bank exceed the calibrated threshold in the same direction.

Conditions for Running the DTC

1. DTCs P0010, P0011, P0013, P0014, P0020, P0021, P0023, P0024, P0341, P0342, P0343, P0346, P0347, P0348, P0366, P0367, P0368, P0391, P0392, P208, P03 , P2091, P2092, P2093, P2094 and P2095 are not installed.

2. The engine is running.

3. The ECM has determined the camshaft positions.

4. DTCs P0008 and P0009 are set continuously if the above conditions are met.

The ECM determines that the position of both camshafts of any engine bank is out of alignment with the position of the crankshaft for more than 4 seconds.

Action Taken When the DTC Sets

DTCs P0008 and P0009 are type E.
Diagnostic Information

1. Inspect the engine for recent engine mechanical repairs. An improperly installed camshaft drive secondary circuit can cause this DTC to appear.

2. One faulty camshaft control actuator or its valve cannot cause this DTC to appear. This diagnostic algorithm is designed to detect a mismatch between the primary intermediate sprocket and the secondary camshaft drive circuit, or a mismatch between the primary intermediate sprocket and the crankshaft. Any of these conditions can cause the cams of both shafts of the same cylinder bank to be out of phase by the same number of degrees.

Circuit/System Testing

1. Clear DTCs with a scan tool.

2. Allow the engine to warm up to normal operating temperature.

3. Let the engine idle for 10 minutes or until the DTC sets. Use a scan tool to get information about trouble codes; DTCs P0008 and P0009 should not set.

Circuit / system test

1. Inspect the camshaft drive chains for wear or misalignment.
If a malfunction is detected in the camshaft drive circuits or tensioners, refer to the "Camshaft Drive Circuit Components" section, Part 1C2, "HFV6 3.2 L Engine Mechanical."

DTC P0041: HO2S Signals Swapped Banks 1 & 2 Sensor 2

Fault diagnostic information

Perform a Diagnostic System Check before using this diagnostic procedure.

Description of circuits / systems

The heated oxygen sensor (HO2S) heater reduces the time it takes for the sensor to warm up to operating temperature and maintains that temperature during extended periods of idling. When the ignition is turned on, ignition voltage is applied directly to the sensor heater. Initially, when the sensors are cold, the ECM controls the operation of the heater by periodically closing the control circuit to ground. By controlling the rate at which the sensors heat up, the chances of the sensors being exposed to thermal shock, which is possible due to condensation buildup on the sensors, are eliminated. After a predetermined period of time has elapsed, the ECM will command the heaters to stay on. After the sensor reaches operating temperature, the ECM may periodically close the control circuit to ground to maintain the desired temperature.
The ECM controls the operation of the heater by grounding the control circuit using a solid-state device, the so-called. drivers. This device is equipped with a feedback circuit that increases the voltage. The ECM can detect an open control circuit, a short to ground, or a short to voltage by monitoring the feedback voltage.

The control oxygen sensor uses the following circuits:

1. Signal circuit
2. Low reference circuit
3. Ignition voltage circuit
4. Heater control circuit

Fault diagnostic information

Perform a Diagnostic System Check before using this diagnostic procedure.

Description of circuits / systems

Oxygen sensors with electric heater are used for fuel control and post catalytic converter control. Each oxygen sensor compares the oxygen content of the ambient air with the oxygen content of the exhaust. The oxygen sensor must be at operating temperature in order to produce the correct voltage signal. A heating element inside the oxygen sensor (HO2S) shortens the time it takes for the sensor to reach operating temperature. Voltage is supplied to the heater through a fuse through the ignition circuit. When the engine is running, ground is supplied to the heater through the low level oxygen sensor (HO2S) heater circuit, through the low level driver in the controller. The controller issues a command to turn the heater on and off in order to maintain the temperature of the oxygen sensor (HO2S) within a certain range.
The controller determines the temperature by measuring the current flowing through the heater and calculating the resistance. Based on the resistance in the controller, the temperature of the sensor is determined. The sensors use pulse-width modulation (PWM) to control the operation of the heater. The controller calculates the resistance of the heater during a cold start of the engine. This diagnostic procedure is performed only once per ignition cycle. If the controller detects that the calculated heater resistance is outside the expected range, these DTCs are issued.

Conditions for Running the DTC

o 1. DTCs P0112, P0113, P0117, P0118 are not set.
o 2. The engine is running.
o 3. Ignition off for more than 10 hours.
o 4. Engine coolant temperature (ECT) sensor parameter at engine start is between -30°C and +45°C (-22°F and +113°F).
o 5. The difference between the ECT sensor and the intake manifold air temperature (IAT) sensor is less than 8°C (14°F) when the engine is started.
o 6. DTCs P0053 and P0059 are issued once per driving cycle if the above conditions are met.

Not at all large in size, the X1 State on-board computer is capable of performing a variety of climatic, route and diagnostic functions. It is installed on cars of the VAZ family - Kalina, Niva, 2123, 2110 and others.

1. What State X1 Can Do - Computer Feature Information
2. Diagnostics with a scanner - are the components of your car working normally?
3. Self-check - decipher error codes

1 What X1 State Can Do - Computer Feature Information

• diagnostic tester. It performs the function of a digital speedometer, tachometer, controls the operation of the power unit and throttle (tuned or standard), reads system diagnostic codes, notifies about the mains voltage in the car and about the engine temperature.
• Trip computer. Useful and convenient mode. In it, the on-board computer at the VAZ State shows the speed (average value) of driving in one trip, the distance traveled by the car, the remaining fuel in the tank and its consumption per trip, travel time. The BC also predicts the range of run on the remaining fuel and has a counter of the latter.
• Supervisor. The device is equipped with an idle time counter and non-volatile memory, it notifies the driver about the direction indicators and dimensions that are not turned off, as well as about the rollback (spontaneous) of the vehicle.
• signaling device. The state reports exceeding the speed limit, malfunctions in the on-board network, and potentially unsafe for auto overheating of the power unit.

• On-board computer VAZ 21099
• Throttle position sensor test
• On-board computer Dingo - practicality with a minimum budget
• Autoscanner for self-diagnosis of any car

In addition, X1 State has three additional features that have appealed to domestic motorists. The Tropic mode implies automatic control of the cooling system of the car, the Plasmer is responsible for drying the candles and their subsequent heating to a temperature that allows the engine to be cold started without any problems, the Afterburner resets when switching fuel from gas to gasoline and vice versa.

A small nuance. The Fast and the Furious function works exclusively with high-quality brands of gasoline (95 and higher). Installation of State X1 is carried out without the slightest difficulty in the plug on the instrument panel.

You will need instructions for installing the BC in a specific model of a VAZ car. The installation principle is the same. It is necessary to remove the overlay from the dashboard, and then alternately connect the one-color factory wiring to the on-board computer wires. State X1 does not need any special configuration. Install the BC, turn on the ignition, start the device, and it immediately goes into the trip computer mode. If you want to switch to the diagnostic mode, press the CORR button. The BC switches to the alarm (emergency) mode on its own.

2 Diagnostics with a scanner - are the components of your car working normally?

Operation of the on-board computer

• THR - throttle position;
• UACC is the battery voltage;
• AIR - air consumption (mass);
• FREQ - rotation (frequency) of the crankshaft;
• INJ - injection pulse duration;
• UOZ - ignition advance;
• FSM - idle speed sensor;
• QT is the fuel consumption coefficient.

3 Self-check - decipher error codes

Every motorist should have a universal device for diagnosing his car.

You can read, reset, analyze all sensors and configure the car's on-board computer yourself using a special scanner ...

Checking the on-board computer

• P0113 and P0112 - incorrect operation of the sensor or failure of the mechanism that controls the temperature of the air flow at the inlet;
• P0106 ​​- incorrect signal from the vehicle motion detector;
• P0172 and P0171 - an increased or decreased indicator of the combustible mixture;
• P0122 (0123) - the throttle circuit is broken;
• P1102 - insufficient signal from the oxygen sensor heater;
• P0647 - malfunction of the clutch of the climate control system;
• P0325 - open knock sensor;
• P0301-0304 - misfires in the cylinders (in one of four or several at once).

Do you still think that car diagnostics is difficult?

If you are reading these lines, then you have an interest in doing something yourself in the car and really saving money, because you already know that:

• Service stations break a lot of money for simple computer diagnostics
• To find out the mistake you need to go to specialists
• Simple wrenches work in the services, but you can’t find a good specialist

And of course, you are tired of throwing money away, and it’s out of the question to ride around the service station all the time, then you need a simple ELM327 AUTO SCANNER that connects to any car and through a regular smartphone you will always find a problem, pay off the CHECK and save a lot.

We have tested this scanner ourselves on different machines and it showed excellent results, now we recommend it to EVERYONE! So that you do not fall for a Chinese fake, we publish here a link to the official Autoscanner website.

An on-board computer is a device that assists the driver in the operation of the vehicle. Today we will talk about the domestic device State Kalina X5 M. The computer is designed specifically for this VAZ model, which makes it easy to connect and use.

1. Standard trip computer options State X5 M
2. New functions of the device - what to expect from manufacturers in the future
3. Do-it-yourself installation of the device - how to avoid mistakes

1 Standard on-board computer options State X5 M

The next useful option is Plasmer. By turning on this function, the owner of Lada Kalina starts the flow of additional impulses to the electrodes of the candles. So on frosty days, Lada starts up much faster, and the computer gives fewer error codes. The "View ECM Errors" function is designed for visual viewing of codes.

Another very useful option for Russian drivers is Fuel Quality Control. Using the "-" or "+" icons, the on-board computer shows the percentage of the quality of the fueled gasoline. Thanks to the "Powertrain Parameters" option, the Lada driver has the opportunity to see a clear picture of the state of the engine; the time spent on heating it; as well as the battery charge level and the voltage indicator in the instrument panel sensors. In the event of a malfunction of the motor elements, the device issues error codes with the name "Engine ...".

The on-board computer State X5 M on Kalina also has a built-in display settings function. Using it, the driver can display on the screen of the device those indicators that are of the greatest importance to him. With the same option, you can adjust the color, contrast and brightness of the display.

Another useful feature is the Gasoline Pump Diagnostics. It controls the pressure and power of the system. This option also makes it possible to determine the status of each injector of the Lada injector.

Error 0500 - "Vehicle speed sensor, no signal."
An error occurs if the controller has determined a sensor malfunction by self-diagnosis.
Causes: moisture ingress into the sensor, damage to the wires.

Ignition on, engine not running. Disconnect the harness connector from the vehicle speed sensor. Using a multimeter, measure the voltage at pin “2” of the harness block. If the voltage is 0 V, then an open or short to ground in the sensor signal circuit or the controller is faulty. If the voltage is about 12 V, then there is a short to the power supply in the sensor signal circuit or the controller is faulty.
With a probe connected to ground, touch terminal “2” of the harness block several times per second, while observing the vehicle speed signal on the BC. If the BC shows a speed of 0 km / h, then the controller is faulty.
Using a multimeter, measure the voltage at pin “1” of the harness block. If the voltage is 0V, then there is an open in the sensor power supply circuit.
Using a multimeter, measure the voltage at pin “3” of the harness block relative to the power supply. If the voltage is 0V, then there is an open in the sensor ground circuit. If the voltage is not 0V, then the connection is loose or the speed sensor is faulty.

Error 0501 - "Vehicle speed sensor, signal out of range."
The error occurs if within 3 seconds the vehicle speed does not match the engine speed and the gear engaged.
The procedure for finding the cause of the malfunction:
Switch off the ignition. Disconnect the harness pads from the controller and DSA. Check the integrity of the electrical circuit between the contact "DSA" of the block to the controller and contact "2" of the block to the DSA, between the contact "Ground of sensors" of the block to the controller and contact "3" of the block to the DSA, between contact "1" of the block to the DSA and the main relay.
If the circuit is faulty, then the wiring harness is faulty. If the circuit is OK, substitute a known-good vehicle speed sensor. Erase the trouble code and reproduce the conditions for the code. When re-entering the code, replace the controller.

Error 0503 - Intermittent vehicle speed sensor signal.
An error occurs if the vehicle speed sensor signal periodically disappears.
Causes: Unreliable contact in the harness pads connected to the speed sensor or controller. Inspect the harness pads, sensor and controller connectors for completeness and correctness of the articulation, damage to the locks, the presence of damaged contacts and the quality of the connection between the contacts and the wire. Harness damage. Check harness for damage. If the tourniquet is outwardly normal, move the corresponding block and tourniquet while observing the BC. Moisture getting inside the speed sensor can also lead to the appearance of code 0503. This happens especially often in spring and autumn.

Error 0504 - "A / B" brake pedal switches, signal mismatch in time.
The error occurs if the signals of the limit switches "1-4/2-3" of the brake pedal are mismatched for more than 200 seconds on a running engine in idle mode or the number of presses on the brake pedal, determined by the signals of the two limit switches "1-4/2-3 " differs by the value of the diagnostic threshold on a moving vehicle.
The procedure for finding the cause of the malfunction:
1 If, when the brake pedal is pressed, the brake lights do not light up intermittently or constantly, check: if the brake pedal switch rod is jammed when the brake pedal is pressed; check the presence of on-board voltage on contacts "1" and "4" of the brake pedal switch in a free and depressed state in accordance with the principle of operation of the switch; check that the relevant fuses in the brake light circuits are intact; check the condition and reliability of the connection of the contacts in the brake pedal switch block.
2 If when you press the brake pedal with the parking lights, direction indicators, reverse gear, fog lights on, a weak glow of the brake lights is observed, check the reliability of the ground circuit of the rear lights.
3 Check the presence of on-board voltage on contacts "2" and "3" of the brake pedal switch in a free and depressed state in accordance with the principle of operation of the switch.
4 Check the continuity of the electrical circuit between the contact "Brake pedal switch 1" of the shoe to the controller and contact "3" of the shoe to the switch, between the contact "Brake pedal switch 2" of the shoe to the controller and contact "4" of the shoe to the switch.
If malfunctions are found, then eliminate the detected malfunctions. If necessary, replace the brake pedal switch.
If no malfunctions are found, then check the technological gap of the brake pedal switch, if necessary, adjust the gap. Erase the trouble code and reproduce the conditions for the code. When re-entering the code, replace the controller.

Error 0505 - "Idle speed controller error".
The procedure for finding the cause of the malfunction:
Start the engine and warm it up to operating temperature. With the throttle closed, use the BC (some models support this function) to change the idle speed in the range from 800 to 1000 rpm. If the speed changes in accordance with the specified ones, then turn off the ignition. Disconnect the block from the IAC. Using a multimeter, measure the resistance of the IAC windings. If the resistance between contacts "A" and "B", "C" and "D" IAC is within 40 ... 80 Ohm, and the resistance between contacts "A" and "D", "C" and "B" IAC is more than 1 MΩ, then check the reliability of the connections in the block. Check the pressure in the fuel supply system, check the injectors for leaks. Otherwise, replace the IAC.
Switch off the ignition. Disconnect the block from the IAC. Connect an idle speed controller tester to the IAC. Start the engine. Using the tester, control the IAC by setting an increase or decrease in idle speed. If the speed does not change in accordance with the specified ones, then check the air channels of the idle system, if they are normal, replace the IAC.
Switch off the ignition. Disconnect the ignition harness connector from the controller. Using a multimeter, measure the resistance in the circuits between the contacts of the IAC block and the block to the controller: "A" and "PXXA", "B" and "PXXB", "C" and "PXXC", "D" and "PXXD". If the resistance is less than 1 ohm, then the controller is faulty. If the resistance is more than 1 ohm, then eliminate the breaks in the circuits.

Error 0506 - "The idle speed controller is locked, low speed."
An error occurs if the current idle correction exceeds the threshold values.
Reasons: too lean or too rich mixture, dirty air filter, faulty IAC or wiring harness.

Disconnect the harness connector from the idle speed control. Connect the tester wires to check the IAC to the battery, then connect its block to the idle speed regulator. Start the engine. Using a tester, control the regulator by setting an increase in idle speed. If the rpm does not change, replace the idle speed control. If the speed increases, then replace the controller.

Error 0507 - "Idle speed controller locked, high speed."
An error occurs if the current idle correction is below the threshold values.
Causes: lean mixture, air leaks, malfunction of the IAC or wiring harness.
The procedure for finding the cause of the malfunction:

Check intake system for air leaks. Check that the crankcase ventilation hoses are connected correctly. If faults are found, they must be corrected.
Disconnect the harness connector from the idle speed control. Connect the tester wires to check the IAC to the battery, then connect its block to the idle speed regulator. Start the engine. Using a tester, control the regulator by setting a decrease in idle speed. If the rpm does not change, replace the idle speed control. If the speed decreases, then replace the controller.

Error 0508 - "Idle speed controller, control circuit short to ground."
An error occurs if the self-diagnosis of the idle speed controller control driver has detected a short to ground at the output.
The procedure for finding the cause of the malfunction:
Switch off the ignition. Disconnect the harness connector from the IAC. With a probe connected to the power source, check the contacts of the harness block. If the probe light does not come on, the idle speed controller is faulty.
Disconnect the harness connector from the controller. With a probe connected to the power source, check that contact of the harness block, during the previous check of which the light came on. If the probe lamp lights up, then the control circuit under test is shorted to ground. If the probe light does not come on, the controller is faulty.

Error 0509 - "Idle speed controller, control circuit short to power supply or open."
The error occurs if the self-diagnosis of the idle speed controller control driver has detected a short to power supply or no load at the output.
The procedure for finding the cause of the malfunction:


Connect the harness block to the controller. Using a multimeter, measure the resistance between the IAC terminals and ground. If during all checks the resistance is 19 ... 21 kOhm, then there is a weak connection in the block of the IAC harness.
Disconnect the harness connector from the controller. Using a multimeter, check the resistance of the wire between the contact of the harness block, on which the resistance is not equal to 19 ... 21 kOhm, and the corresponding contact of the controller block. If the resistance is less than 1 ohm, then the controller is faulty. If the resistance is more than 1 ohm, then repair the open circuit.

Not at all large in size, the X1 State on-board computer is capable of performing a variety of climatic, route and diagnostic functions. It is installed on cars of the VAZ family - Kalina, Niva, 2123, 2110 and others.

1

The on-board computer (BC) we are interested in has a fairly wide functionality. It works in the following modes:

• diagnostic tester. It performs the function of a digital speedometer, tachometer, controls the operation of the power unit and (tuned or standard), reads system diagnostic codes, notifies about the mains voltage in the car and about the temperature of the motor.
• Trip computer. Useful and convenient mode. In it, the on-board computer at the VAZ State shows the speed (average value) of driving in one trip, the distance traveled by the car, the remaining fuel in the tank and its consumption per trip, travel time. The BC also predicts the range of run on the remaining fuel and has a counter of the latter.
• Supervisor. The device is equipped with an idle time counter and non-volatile memory, it notifies the driver about the direction indicators and dimensions that are not turned off, as well as about the rollback (spontaneous) of the vehicle.
• signaling device. The state reports exceeding the speed limit, malfunctions in the on-board network, and potentially unsafe for auto overheating of the power unit.

On-board computer State X1

In addition, X1 State has three additional features that have appealed to domestic motorists. The Tropic mode implies automatic control of the cooling system of the car, the Plasmer is responsible for drying the candles and their subsequent heating to a temperature that allows the engine to be cold started without any problems, the Afterburner resets when switching fuel from gas to gasoline and vice versa.

A small nuance. The Fast and the Furious function works exclusively with high-quality ones (95 and above). Installation of State X1 is carried out without the slightest difficulty in the plug on the instrument panel.

You will need instructions for installing the BC in a specific model of a VAZ car. The installation principle is the same. It is necessary to remove the overlay from the dashboard, and then alternately connect the one-color factory wiring to the on-board computer wires. State X1 does not need any special configuration. Install the BC, turn on the ignition, start the device, and it immediately goes into the trip computer mode. If you want to switch to the diagnostic mode, press the CORR button. The BC switches to the alarm (emergency) mode on its own.

With the help of the on-board computer, the State checks the car. It is carried out with or without a scanner. In the first case, you need to connect the described BC to a laptop or tester (they must have the appropriate software) using a special cable for diagnostics. The scanner itself is connected to the connector located near the gearbox (near the selector) via an OBD-II adapter. The latter makes it possible to send diagnostic information to a laptop via the USB output.

Operation of the on-board computer

After that, you install the program (usually the KWP_D utility is used), turn on the ignition and proceed with the diagnosis. Deciphering the received codes allows you to find out which parts of the machine are not functioning as required. This means that they need to be configured. Diagnostics shows the following parameters:

• THR - throttle position;
• UACC - battery voltage;
• AIR is the flow rate (mass) of air;
• FREQ - rotation (frequency) of the crankshaft;
• INJ - injection pulse duration;
• UOZ - ignition advance;
• FSM - idle speed sensor;
• QT is the fuel consumption coefficient.

Having received all this data, you need to compare them with the standard values ​​\u200b\u200bthat are recommended by the automaker. If the numbers differ from each other by 18–20 percent, then everything is in order with your car. If the difference exceeds 20%, the problem nodes should be adjusted.

BC State X1 allows you to diagnose the functioning of individual vehicle components without the use of scanners, laptops and other electronic devices. Checking the car in this case is done as follows - press the button to reset the daily mileage on the dashboard and immediately turn on the ignition (you do not need to start the engine itself).

Checking the on-board computer

After such actions, the BC will start diagnosing the instrument panel. Then you need to turn on the windshield wipers (just press the appropriate button - it is located on the start lever of the specified device) and watch how various fault codes appear on the State display. A breakdown of common errors is given below:

• P0113 and P0112 - incorrect operation of the sensor or failure of the mechanism that controls the temperature of the air flow at the inlet;
• P0106 ​​- incorrect signal from the vehicle motion detector;
• P0172 and P0171 - an increased or decreased indicator of the combustible mixture;
• P0122 (0123) - the throttle circuit is broken;
• P1102 - insufficient signal from the oxygen sensor heater;
• P0647 - malfunction of the clutch of the climate control system;
• P0325 - open knock sensor;
• P0301-0304 - misfires in the cylinders (in one of four or several at once).

Note! Any decoded code tells us about a real malfunction. Therefore, you definitely need to contact a car service or solve the problem yourself if you have the skills to perform simple repairs to your car.

Error codes VAZ 2110 are presented in numerical designation on the display, and they are transmitted from the phase sensors to the on-board computer. This is convenient, but a novice driver will not be able to understand much and will not be able to figure out how to use this equipment. But you need to know and be able to do this, since the system, thanks to the built-in self-diagnosis function, will help to identify a malfunction in the early stages, which means that it is possible to eliminate it in a timely manner.

Diagnostics

There are two ways to diagnose the condition of a car's systems. Let's start with the first one, which does not involve the use of additional equipment.

To start the self-diagnosis function, you need to press a button that resets the mileage per day. We turn on the ignition. You will see how the arrows on the instruments begin to move from one position to another. It means that the diagnostics of the VAZ 2110 has been launched and information has begun to flow from the phase sensors to the computer. After the process is completed, the RAM will send numbers to the display that will show the state of the auto systems.

Car VAZ 2110

Deciphering combinations

When the self-diagnosis is completed and the number 0 is displayed, this means that everything is in order with the vehicle and all systems are working as expected:

• if 1 is displayed, this indicates that there is a problem with the microprocessor or the RAM is failing;
• 4 - high voltage in the network, more than 16 V;
• if 8, then low.

If the fault is not one, but several, then a number equal to the sum of the faults will be displayed. If 6 lights up, then this will mean the sum of the numbers 2 and 4. If 14, then most likely three faults at once, namely 2, 4 and 8.

The simplest diagnostics that is available to the driver without the use of additional equipment. Of course, it will help to identify some malfunctions, as well as show the status of the nodes and the VAZ 2110 system as a whole. But for a specific definition of all malfunctions and decoding of information coming from phase sensors, additional tools are needed. For example, which provides more data.

Trip reset button

Diagnostics with additional tools

To diagnose a car, including the VAZ 2110, various equipment is used that is connected to a special connector. Thanks to this equipment, which is not particularly complex and high price, you can get a complete picture of the condition of the car.

The service station uses a personal computer, to which data from the phase sensors are transmitted through a special cable.

Adapter for car diagnostics

Bluetooth devices have appeared on the market that allow you to diagnose using a smartphone, tablet or laptop.

They work according to the plan. The device is connected to the connector, the ignition is turned on and the diagnostic process begins. The data comes from the phase sensors to the ECU. From it to a mobile device, on which specialized software must first be installed.

This makes it possible not only to obtain more data, but also to present them in a more visual form. This method allows the driver, even with little experience in operating a car (in our case, the VAZ 2110), to receive all the data about his car.

But most drivers prefer to carry out diagnostics at the service station. In order for you to be aware of the data that the on-board computer issues through the RAM from the phase sensors, we will present the decoding of common errors.

Deciphering combinations

If problems arise with electrical equipment, they must be fixed immediately. The fact that in this matter not everything is in order will show error code 1602.

Sometimes error 1602 can simply be reset and not appear again. Socialists call such data "good".

Error 1602 sometimes appears if:

• the battery has been disconnected for a while;
• there was a power surge during the start of the motor, for example, in cold weather.

But if error code 1602 appears all the time, you need to check the entire network. Perhaps there is a break. If error code 1602 constantly appears, you can try to clean the battery terminals. Check if they are well fixed. Didn't help, error 1602 still appearing? Check the circuit. You need to start from the positive terminal of the battery. Start with an electrical fuse and a fuse link.

DPS. Sometimes it happens that the cause of error code 1602 is an alarm that can block the controller circuit and affect the readings of the phase sensors. In such a situation, you need to file a claim with the company that dealt with

• low air consumption, which depends on the speed of rotation of the crankshaft;
• how open the throttle is;
• Several cycles have passed since the problem occurred.

If the error appears intermittently, then you need to:

• check the condition of the air barrier;
• fastening the wiring block with the computer;
• check IAC;
• clean the throttle body.

Another error that can occur is 0300. 0300 appears in cases where the RAM detects frequent misfires.

If error code 0300 is displayed constantly, then you need to check the following nodes:

• spark plug;
• nozzles;
• ignition system;
• an increased or decreased compression level may be the cause of code 0300;
• also code 0300 may appear in the event of a wiring violation.

The appearance of error 0300 cannot be ignored. In the future, this may lead to a deterioration in the operation of other nodes.

It is not difficult to master the diagnostics of a car, in particular the VAZ 2110. It will extend the service life due to the timely detection of faults that fix the phase sensors.
