Method of reading of blinking codes by a lamp Check up the engine (It is possible on some models)

 INSTALLATION

1. Include ignition.
2. Five times within five seconds completely squeeze out and release an accelerator pedal.
3. If in memory of the processor codes of taking place malfunctions are brought, they will start to be highlighted consistently by a control lamp “Check up the engine” on a car control panel.
4. Consider a blinking code.
5. The lamp lights up on 5 сек, through 0.5 сек again lights up on 2.5 сек, and through an interval 2.5 сек the code stands out. Value of each category of a code corresponds to quantity of flashes with an interval 0.5 seconds
At first the senior categories of a code, the last – units stand out. Intervals between code categories - 2.5 seconds After delivery of a code a lamp it is necessary to burn.

It is necessary to mean that codes (on different models) can be as decimal, and 16-richnymi. In the second case the quantity of flashes designating the code category can accept value from 1 to 16. Categories 16-richnogo a code are designated one after another so: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F. For example, the code 7F is reflected by 7 short flashes and, after a break 15 short flashes.

Repeat procedure to consider the subsequent codes.

Engine start automatically interrupts access to diagnostics system.

Clearing of memory OBD

At entering of a code of malfunction in memory РСМ on an instrument guard of the car the control lamp “lights up Check up the engine”. The code remains written down in memory of the module.

For clearing of memory ЕСМ connect to system the scanner and choose in its menu function CLEARING COEDS (Removal of codes). Further follow the instructions highlighted on the device, or at once for 30 seconds take from the nest in the assembly block safety lock EFI.

Alternatively clearing of memory of system can be made by removal of a fusible insert (the main safety lock of system of onboard power supplies), the battery established near to the positive plug (it is possible to disconnect simply also from the battery a positive wire).

It is necessary to mean that at clearing of memory OBD by a detachment of a negative wire from the battery, adjusting parametres of the engine are erased and stability of its turns for short time after primary start is broken.


If the stereosystem established on the car is equipped by a security code before to disconnect the battery, make sure that have a correct combination for audiosystem input in action!


Battery switching-off also leads to removal of options of the receiver on favourite radio stations. Attention: In order to avoid damage ЕСМ its switching-off and connection should be made only at the switched off ignition!

Track, that memory of system has been cleared before installation on the engine of new components of systems of decrease in toxicity of the fulfilled gases. If before start of system after replacement of the failed information gauge not to make clearing of memory of refusals, РСМ will bring in it a new code of malfunction. Memory clearing allows the processor to make change-over on new parametres. Thus, in the first 50 20 minutes after primary start of the engine, can take place some infringement of stability of its turns.
