Opel Fault Codes List

The table shows the error codes for the Mercedes engine. To find a word or phrase on the page, press Ctrl + F in the window that appears, enter the error code or part of the phrase and click the "Find" button, as a result, the decoding of the specific Mercedes error code you are interested in will appear.

In modern electronics with computer microcircuits, system bypasses for the "admin" are laid. This is a set of actions that starts the mode of displaying error codes in the on-board computer by flashing lamps. To see the error codes Opel, without resorting to paid reading services using devices, use such a bypass system. Manipulation schemes are very simple, but different for vehicles with different gearboxes.

To diagnose a car with a manual gearbox, follow these steps:

1. Sit behind the wheel, press the gas and brake together.
2. Place the key in the lock hole without releasing the pedal.
3. Make one revolution with the key, without starting the engine.
4. Remain in that position until the inscription flashes on the instrument panel, where the mileage of the car is indicated.

For the automatic transmission Opel Zafira B steps a little more, but the meaning is the same:

1. While driving, insert the key into the ignition switch.
2. Make a revolution with the key, without starting the engine.
3. Clamp the brake pedal.
4. Set the box lever to position D.
5. Turn off the ignition, remove your foot from the brake.
6. Press the accelerator and brake pedals at the same time.
7. Turn on the ignition without starting the engine.
8. Remain in this position and wait until the inscription with numbers and / or letters flashes on the parting panel.

It is important to activate the limit switches during the “call” of errors. To do this, squeeze the gas all the way until a click occurs, and at the same time press the brake pedal.

How to decrypt correctly?

As a result of self-diagnosis, a malfunction code will appear on the dashboard screen, indicated by a letter and several numbers or just a set of numbers. The inscription ECN and any other numerical combination, except for zeros alone, indicates the presence of errors and problems in the operation of the car.

In five-digit codes, the Latin letter comes first:

“B” - a problem with the body;

“C” - chassis problems;

“U” - indicates a malfunction with the inter-unit data bus;

"P" - indicates a problem with the engine and gearbox. This letter is also present when the computer issues a 4-digit numeric code.

Next is the numerical combination, where the first digit after the letter:

0 - designation common to all OBD-II codes;

1 and / or 2 - manufacturer code;

3 - backup code.

The second digit of the five-digit error code in the Opel shows the type of problem, and the last two are the number of the specific malfunction within the same type. An example of such a frequently appearing code is P0170, which stands for “improperly balanced mixture composition”. If this error is detected, it is recommended to clean the nozzles, throttle, and also the intake manifold EGR valve and its channels as a solution. They are clogged with soot on average over 50-80 thousand kilometers.
