Was bedeutet der Fehlercode?

The CEM has registered that communication with the SRS control module is not working, and the fault code is set. The SRS warning lamp may light. The fault concerns the airbag system, and all work on it is done by a workshop.

Mögliche Ursachen

No power supply to the SRS control module
Break in the earth wire to the SRS control module
Contact resistance in the terminals
Open circuit in the CAN wiring to the SRS control module
The SRS control module is not meant for this car, for example a used module with other software or hardware

Was Sie tun können

1Check that the SRS warning lamp in the instrument panel lights when the ignition is switched on and goes out after a while
2Do not clear the code yourself or replace the CEM for CEM-1A5X codes; they point to a CAN communication fault
3Safety note: do not work on the airbag system yourself; have a workshop check the SRS control module and its wiring with diagnostic equipment
