If the dashboard lit up the inscription «Check Engine», the driver will be clear that it is time to check the engine. The only problem is that this indicator - it is too general, broad information, which does not give a specific breakdown. At the same time, more and more modern cars equipped with onboard computers that collect sufficient information about the current state of the car. In particular, they can provide information about errors and breakdowns in the form of codes, for which it is necessary to use a combination of pedal cars.

How this is done with manual transmission: Machines with a mechanical transmission simultaneously pressed gas and the brake, and the ignition is switched without starting the engine. The computer will display the codes breakdowns and errors, if any. Numbers appear to be rewritten and decipher. Each set will indicate a problem with some assembly.

How this is done in the automatic transmission: On machines with automatic transmission are pressed the gas and brake, and turn on the ignition without starting the engine. You will also need to translate the selector in Drive mode. After all done, without releasing the pedal, turn off the ignition and turn it on again. By doing this we get on the dashboard special code on failure.

Important: Decipher the code with faults or online help, or the user of a particular vehicle. All this will help to find out more specific cause of the failure, even before applying to the service station.

The resulting codes are called ECN. Usually they consist of a letter and four digits. Letters can mean the following: B - body, C - chassis, P - the engine and gearbox, U - inter-unit bus data exchange. The first digit can be from 0 to 3 and mean values, respectively, Generic, «factory" or "reserve". The second digit is the system or control unit function, and the last two make up the error code number. Thus the error is directly represent only the first four characters.
