Method of reading of the blinking codes on a lamp "Check the engine" (It is possible on some models)
It must be kept in mind that codes (on different models) can be both decimal, and 16-richny. In the second case the number of the 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 7 short flashes and, after a break 15 short flashes. Repeat the procedure to consider the subsequent codes. Start of the engine automatically interrupts access to system of diagnostics. 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 the scanner to system and choose the CLEARING COEDS function (Removal of codes) in its menu. 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 removal of a fusible insert (the main safety lock of the system of onboard power supply) installed close the positive plug of the battery (it is possible also just to disconnect a positive wire from the battery).
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 start of system 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. At the same time, the first 50 ÷ 20 minutes after primary start of the engine, some violation of stability of its turns can take place. |
