Data on diagnostic devices
Description of system of onboard diagnostics
Method of reading of blinking codes by a lamp “Check the engine” (It is possible on some models)
Method of reading of blinking codes by a lamp «Check the engine» (It is possible on some models)
It is necessary to mean that codes (on different models) can be both decimal, and 16-richny. In the second case the number of flashes designating the category of a code can accept value from 1 to 16. Categories of a 16-richny 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.
Cleaning of memory of OBD
When entering a code of malfunction in memory of RSM on an instrument guard of the car the control lamp “Lights up check the engine”. The code remains written down in memory of the module.
For cleaning of memory of ESM connect to system the scanner and choose in its menu the CLEARING COEDS function (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 EFI safety lock.
Alternatively cleaning of memory of system can be made by a way of removal of a fusible insert (the main safety lock of system of onboard power supply), the battery established near the positive plug (it is possible to disconnect also simply from the battery a positive wire).
Track, that memory of system was cleared before installation on the engine of new components of systems of decrease in toxicity of the fulfilled gases. If before system start after replacement of the failed information sensor not to make cleaning of memory of refusals, RSM will bring in it a new code of malfunction. Cleaning of memory allows the processor to make change-over on new parameters. Thus, the first 50 ÷ 20 minutes after primary start of the engine, some violation of stability of its turns can take place.
