how to see errors on the on-board computer of a VAZ 2114 trip computer

It’s terribly useful to do both the first and the second, and the third is basically “oil”! This is how you can cure any patient - disconnect the oxygen, go for a smoke, you come.

and he smokes too!

These are messages about factory testing of BOSCH 7.9.7+ Euro3 KSUD, as far as I understand. Try this: 1. Starting position: ignition off, battery on. 2. While holding down the daily mileage reset button, turn on the ignition. All positions of familiarity areas (segments) should light up on the LCD, which indicates the start of self-testing. 3. Press any of the on-board computer control buttons. The LCD should display the program version (Ver 1.0 and higher). 4. Press any of the control buttons again. The following error codes (if any) should be displayed on the positions of the first and second lines of the LCD:

2 — increased voltage of the on-board network; 3 — fuel level sensor error (if a break in the sensor circuit is detected within 20 s); 4 — coolant temperature sensor error (if an open circuit of the sensor is detected within 20 s); 5 — error of the external temperature sensor (if there are no sensor readings within 20 s, the indication on the LCD is “-C”); 6 — engine overheating (the criterion for triggering the acoustic alarm is met); 7 — emergency oil pressure (the criterion for triggering the acoustic alarm is met); 8 — defect in the brake system (the criterion for triggering the acoustic alarm is met); 9 — the battery is discharged (the criterion for triggering the acoustic alarm is met); E - error detection in the data packet stored in the EEPROM.

5. If necessary, you can reset error information. To do this, press and hold down the daily mileage reset button for 3 seconds. 6. Press any of the control buttons again. All positions of the familiar areas (segments) should light up on the LCD - the system has returned to the state of point 2. 7. If you do not press any control buttons for about 15-30 seconds, the panel goes into operating condition.

Where did you see the zero? I’m curious. You had or have the following errors: 3 - fuel level sensor error (if an open circuit of the sensor is detected within 20 s); 4 — coolant temperature sensor error (if an open circuit of the sensor is detected within 20 s);

5 - error of the external temperature sensor (if there are no sensor readings within 20s, the indication on the LCD is “-C”; Resetting does not cure. Before resetting, always read what happened. If there are repetitions of the same errors, you need to figure it out. Anyone who thinks that a reset He’s treating something there, they’re just idiots.

Decoding errors

Each code consists of five characters: P 1 4. Let's say right away about the fourth and fifth characters - they indicate the serial number of the error. Now it’s worth taking a closer look at what the codes consist of

The first character may vary depending on the vehicle system:

• P – malfunctions in the operation of the power plant; the symbol also indicates defects in the automatic transmission.
• U – you need to look for a fault in the interaction node between the system units.
• B – defects in the operation of body systems, which include electric lifts, airbags, etc.
• C – chassis sensors have detected a malfunction in the chassis system.

Error code P1602 indicates that the controller power supply voltage is lost.

Error P1602 stands for “Control system controller, loss of on-board power supply voltage.” In the understanding of this error, the controller means the electronic engine control unit (ECU), since the error begins with the letter “P”.

p, blockquote 1,0,0,0,0 —>

p, blockquote 2,0,0,0,0 —>

This error belongs to the class of system errors, since it does not specifically indicate a faulty device or unit. Therefore, eliminating error P1602 is carried out by monitoring possible locations of the malfunction.

p, blockquote 3,0,0,0,0 —>

p, blockquote 4,0,0,0,0 —>

Error 1602

If error 1602 appears on the on-board computer of the Lada Priora 16 valves, this means that the on-board voltage in the controller has dropped. As the experience of VAZ 2170 owners shows, error 1602 does not affect the operation of the car; if you remove the terminal from the battery, then 1602 will disappear, but after a while it will appear again. There may be several reasons for 1602:

• Problems with the generator. Measure its voltage; in good condition it produces 13.7-14 V.
• A large voltage drop during engine starting also leads to the appearance of 1602. The ECU records the voltage drop and automatically adjusts the time. First of all, you need to check the ground on the electronic control unit.
• Codes 1602 appear when the security system blocks one of the electrical circuits.

What does code P0507 mean?

Trouble code P0507 is triggered when the engine idle speed is higher than expected. All modern engines have a desired idle speed - usually between 600-1000 rpm.

The control unit uses position sensing and throttle adjustment to achieve these speeds. If the idle speed exceeds these set values ​​and the maximum adjustment zone, the control unit will generate this error code.

Code P0507 is a common code for vehicles equipped with Electronic Throttle (E-Gas). Newer vehicles usually use E-gas.

The throttle valve is only called electronic. It replaces the old throttle body with a cable between the gas pedal and the throttle body.

The electronic throttle body uses sensors on the gas pedal and an electric motor in the throttle body to provide the desired acceleration. But this does not mean that this error code must necessarily be related to a faulty throttle valve. It can also have many other causes.

p0504

Also, many owners of a Lada Priora with 16 valves have questions about the appearance of error p0504. She tells the owner that there is a malfunction in the brake pedal sensor. To find out the exact reason for the appearance of p0504, you need to remove the sensor and disassemble it. Pay attention to its springs, one of them could burst - replace the damaged part.

Another reason is copper contacts, which can burn. Inspect them and clean them if necessary. Sometimes error p0504 pops up due to the incorrect position of the brake pedal sensor on Priora 16. Twist it and check whether codes p0504 remain on the screen or not.

HOW TO DIAGNOSIS THE ECM
Here in the first place is the IAC, a device that regulates the supply of additional air bypassing the throttle valve. It works by means of a micromotor that extends and retracts the shutter mechanism. If there is a malfunction, the engine will not start at idle. Or, conversely, it increases the speed to 1500-2000.

Error 0422

The efficiency of the Priora 16 neutralizer has fallen below the normal level - this is what error p0422 reports to the owner of the Lada Priora 16 valves. As practice shows, codes 0422 pop up quite rarely. If code 0422 appears on the on-board computer screen, then you need to perform the following steps:

1. We examine the catalytic collector. Its body and filling must be in good condition;
2. If damage is found, the catalytic collector should be replaced with a serviceable one;
3. If the catalytic converter is not the cause of the message, then the remaining actions to eliminate p0422 must be entrusted to specialists from the service center.

To get rid of 0422 you will need to reflash the cathode collector. If you have the equipment to set the settings, you can do the work yourself.

Car diagnostic process using tester or plug-in Much

computer, more accurate and reliable data for checking the car for malfunctions can be obtained if separately connected equipment is used. But the use of such tools and devices gives encrypted readings, so that, therefore, to correctly understand and find everything in the car that is faulty, you need to decrypt the data received from the device diagnostics.

But the sensor is that the Lada Priora is produced not only for the domestic market, it is also produced for sale in other countries. Therefore, such a classification of automobile problems and their code-checking device was created.

It is easier to enter a certain number of universal codes into the program than to enter your own language data for each person for the national market. As a result, you can look at the code on a specific display and easily determine the essence of the problem using the auto list, which lists all encrypted codes. A special code is used to indicate error codes on the Lada Priora car. This cipher includes:

• alphanumeric code;
• fault code for the location of the fault in the Lada design.

On a Priora car, all space codes in the car will have five digits. complete Here is a list of Priora designations. The first character of the code will be a Latin letter. The letter “P” indicates a problem with the engine, or more precisely with its electronic letter. system “B” signals problems with the interior electronics.

The “C” letter is present on the screen only if there is an electronic failure in the vehicle chassis system. If errors occur combined in several operating systems of the vehicle, the letter “U” will appear on the display. The letter designation is followed by a number.

The zero indicator is indicated by the code Digit-2. OBD 1 and 2 show the company code, and the third digit is responsible for the backup code. The subsequent set of numbers conditionally shows the place where errors were detected during diagnostics. A zero code indicates emissions to the system. Number 1 indicates the fuel number, system 2 indicates the air supply system.

If there is a malfunction in the ignition, the number 3 will appear. If there are problems with additional control, the number 4 will appear. If there is a malfunction in the ignition, then the number 5 is responsible for this, and the number 6 will appear for problems with the ESC. Numbers 7 and 8 are associated with the transmission In the general code, the very last two digits indicate the error number in the operation.

How is self-diagnosis performed?

We have sorted out the main errors on the Priora, now it’s worth finding out how self-diagnosis is performed. The VAZ 2170 with 16 valves has a special controller with which diagnostics are performed. If you have an on-board computer installed, then diagnostics are performed on it. There is also special equipment that allows for a more in-depth check of Priora 16 class systems.

Since most Priora 16 cars already have an on-board computer, we will consider the option without the use of special devices. Diagnostics begins with activation of the test mode. The work proceeds according to the following scheme:

1. Turn off the ignition. Now we hold down the daily mileage reset button, without releasing the button, we start the ignition of the Priora 16 cl;
2. On the instrument panel you will see a display with an indication. After turning on the ignition, all components of the instrument panel will light up. The needles of the temperature, speedometer, tachometer and other instruments will begin to move to the maximum level and back. This behavior indicates that self-diagnosis has begun;
3. Let's move on to the right steering wheel switch. Here you will find a button for switching the on-board computer settings. Click on it, a message with the software version will appear on the instrument panel screen;
4. The instrument panel error diagnosis will begin if you press this key again. Various codes will appear on the display, which you can decipher in the table below;
5. When the diagnostics are complete, you can reset the error data. Press and hold the daily mileage reset button for about 5 seconds.

System high voltage

Description of the scheme

The ECM monitors the ignition voltage through the ignition circuit to terminal K18 on the ECM. Any signal value above the calibrated value will set a system voltage diagnostic trouble code.

Conditions for Setting the DTC

• The system voltage is less than 16 V.
• Engine running

Action Taken When the DTC Sets

• The malfunction indicator lamp does not light up.
• The controller records the operating conditions at the time the fault is detected. This information is stored in fault logs.
• An archive of diagnostic trouble codes is saved.

Conditions for Clearing DTC/Malfunction Indication

• The DTC history is cleared after 40 consecutive heating cycles without faults.
• The DTC can be cleared by a scan tool.
• The ECM power supply is turned off for more than 10 seconds.

Diagnostic information

If the DTC sets while the accessory drive is operating, check for loose connections or high current. Any circuit that may be causing an intermittent fault should be carefully checked for the following:

• Removed terminals
• Terminal connection
• Lock malfunction
• Deformity
• Terminal damage
• Poor contact between terminals and wiring connectors.
• Physical damage to wiring harnesses

Description of the test

The numbers below indicate the operation numbers in the diagnostic table.

1. The On-Board Diagnostic (EOBD) system prompts the technician to perform basic checks and store status and fault data in the scan tool. This creates an electronic copy of the data recorded when a fault occurs. The information is stored in the scanning device for further processing.
2. This test is carried out if the generator fails under load.
3. The replacement ECM must be programmed. Reprogramming the ECM is described in the latest Techline.
4. If no faults have been detected at this stage and no additional fault codes have been set, then see this Diagnostic Information section for additional test information.
