Co oznacza ten kod błędu?
At ignition, the engine control module (ECM) should ask the central electronic module (CEM) for the immobiliser code and compare the answer with its own. The fault shows that the CEM has not received a request from the ECM within the expected time, so engine start is not permitted.
Możliwe przyczyny

Co możesz zrobić
- 1Read off and note the code, clear it and check whether it returns when you try to start
- 2Check that the battery is in good condition, since low voltage can disturb communication between the modules

- 4If the fault remains, have a workshop check the engine control module and the communication between the modules
