General Error codes Volvo (cargo cars)

R0173. - This code suggests that the control unit has registered gasoline leakage from fuel system The second motor cylinder block. To remove this error, you need to eliminate fuel leakage.

R0174 - R0175 - The combustible mixture in the second cylinder block is too poor or rich.

Р0200 - The computer has registered a malfunction in the wiring chain of the Volvo engine nozzles. It should be diagnosed with wiring for cliffs and closures. It often occurs after the rain when short circuits may arise with a greater probability due to wiring worn.

Р0201 - Р0212. - One of these combinations reports a motorist that in electrocups of the control of one of the twelve nozzles caused malfunctions, that is, it can flow an incorrect signal or a circuit or a closure.

Р0213 - Р0214 - These combinations indicate emerged cliffs or closures in electrocipers of control of one of two nozzles of the cold start.

Р0215 - The on-board computer Volvo reports an error associated with the failure of the car shutdown solenoid. Often such a move is found in vOLVO cars S80, relating to it most frequent on this model.

Р0216. - On the car control unit, information about the cliff of the injection time control circuit is received. The overall mistake of the brand is found on most models.

Р0217. - Overheating of the car motor. This malfunction code Volvo is "treated" by adjusting the coolant temperature. If everything is in order and antifreeze in expansion tank Do not boil - you need to pay attention to the coolant temperature sensor. It can assume including because of hot weather.

Р0218. - Auto control unit reports motorist about overheating transmission system. In such cases, some motorists disassemble the gearbox to make sure whether the oil temperature in the transmission is really high. Often the problem is in the incorrect operation of the temperature sensor temperature unit. It is subject to replacement.

Р0219 - This combination indicates an overly high turnover of the motor. It is possible to adjust the idling sensor.

Р0243 - Р0246. - These errors in the diagnosis of the car reported talk about the failure of the solenoid shutter of the exhaust gases of the first turbine. Also, error data may mean an incorrect signal coming from the element. The solenoid can be both closed and open.

Р0247 - Р0250 - The appearance of one of these codes in the diagnosis of Volvo suggests that the solenoid of the shutter gases of the second turbine is faulty. Such errors may mean an incorrect signal coming from the element. The solenoid can be both closed and open.

Р0251 - This code means the failure of the injection pump of the first turbine.

Р0231 - Р0233 - The control unit has registered the incorrect signal coming from the secondary chain of the gas station. You should check the wiring for cliffs to eliminate the error.

Р0261 - Р0263 - This combination means the failure of the drive driver of the first engine nozzle or the wrong signal coming from it. You need to check the driver's performance and replace it if necessary.

Р0264 - Р0266. - The computer speaks about the driver's second motor nozzle driver or malfunction in the element chain.

Р0267 - Р0296 - One of these combinations means the failure of the driver of the third - twelfth nozzle. Also such codes may indicate problems in the operation of electrocups. You need to more thoroughly digitize the wiring to reveal the breaks or closures or replace the driver. In some cases, it is required to replace directly nozzles.

Р0300 - The Volvo operating computer reports the registered ignition pass. May indicate serious problems with load balancing.

Р0301 - Р0312. - The on-board computer of the vehicle recorded ignition skipping in one of the twelve engine cylinders.

Р0380 - The control unit is registered a breakdown of one of the incandescent candles. Moreover, this code It may indicate a malfunction in the heating circuit. It is recommended to check the chain or replace one of the candles.

Р0381 - Such a combination can also mean failure of one of the aircraft. But, in addition, it may indicate the failure of the device heating indicator.

Deciphering error codes allows the car owner to detect and eliminate the malfunction that appears during the operation of the vehicle. In this case, Volvo cars are no exception. If you are the happy owner of this car brand, then we invite you to find out how the Volvo FH12 error codes are decrypted and how to make the car diagnostics.

Diagnostics of cars

If you notice that on your Volvo caught fire check Light Bulb Engine Either while driving the car does not work as usual, then you need to check the car for faults. In particular, we are talking about self-diagnostics of the vehicle and decrypt error codes.

In Volvo cars appearance And finding depends on the year of the vehicle. For example, to decrypt code errors in Volvo vehicles released until 1995, you must use the old-type connector. In the machines released after 1995, there is a special OBD-2 connector with sixteen contacts. Depending on the car model, the connector may be located in different places, but in any case it is in the cabin car:

• under the dashboard on the driver's seat;
• inside the armrest;
• opposite the gearbox switching lever;
• next to the parking brake lever.

In the case of the OBD-2 connector, motorists should not have questions, but if you have an old type in your car, you will be useful to know that:

• the A1 connector is responsible for the diagnosis. automatic box gears;
• the A2 connector is responsible for the diagnosis of the engine, in particular, the fuel system;
• a3 connector - for checking the ABS block;
• a5 connector - for the diagnosis of automatic transmission - TCU;
• the A6 connector allows you to check the ignition system for faults;
• A7 allows you to check the car instrument panel;
• the B1 connector allows the motorist to check the performance of climate control and air conditioning;
• connector B2 - to diagnose the speed maintenance system in automatic mode;
• B5 - check the health system, in particular - pillows;
• B6 is responsible for the work of the Situation Management System.

To find out exactly where you are located in your Volvo to diagnose error codes, we recommend that you use the manual for use for your car. How to make diagnostics? This question interests everyone owner Volvo.who collided with the need to decrypt the fault combinations. For this you need:

1. Rotate the key in the ignition lock, not launching the engine.
2. Insert the probe block to diagnose into the socket of the pads (for auto models released until 1995). For cars released after 1995, you need to connect the indicator to the OBD-2 connector. In particular, the advantage terminal must be connected to a 16 connector, and the minus - to the fourth, simultaneously connecting the probe with the socket with the corresponding unit for diagnosis.
3. Next, you need to click the button located on the indicator (you do not need to clamp for a long time).
4. The LED light bulb will flash: it is necessary to read error codes and decrypt them.

Consider the fact that independent diagnostics may be inaccurate. The on-board computer may incorrectly show the breakdown. To obtain more accurate malfunctions, it is recommended to diagnose the vehicle on specialized equipment.

Deciphering codes

Consider a description of the combinations of errors that may appear at Volvo. In fact, these codes are not one thousand, but we will not consider them all. We will pay time only to those combinations that are most often found in Volvo machines. So, proceed.

Sensor errors

Engine faults

Erasing errors

If you considered and decrypted combinations of errors, and also eliminated the breakdown, then you need to erase the code from the memory of the on-board computer. Otherwise, it will be shown again, which can mislead the motorist.

1. You must click and hold the button on the indicator for more than 5 seconds.
2. Then you need to release the button and wait until the light on the device starts to burn continuously. As a rule, it burns for about 10 seconds. In this case, the LED should not blink.
3. After that, press the button again on the indicator and wait about 5 seconds, but not less.
4. Release the button. If you are all done correctly, the lamp will go out.
5. The indicator must blunt three times (combination 1-1-1) - this indicates that errors in the memory of the on-board computer are not detected. If you did something wrong, then repeat the action starting from the first item.
6. Turn off the ignition and disconnect the minus battery terminal for 10 seconds.

On this, the process of diagnosing and erasing errors can be considered completed. Remember that a list of combinations and faults in vehicles Volvo can be supplemented because the manufacturer of the car can introduce new combinations with the release of new models.
