Was bedeutet der Fehlercode?

The CEM has lost contact with the supplemental restraint system module (SRS), and the SRS warning lamp in the instrument cluster comes on. The fault is most often caused by supply, earth or a connector at the SRS module, or by a break in the LS-CAN wiring.

Mögliche Ursachen

No supply to the SRS module
Break in the earth connection to the SRS module
Contact resistance in the connections
Open circuit in the LS-CAN wires to the SRS module
The SRS module does not suit the car, for example a used module with other software or hardware

Was Sie tun können

1Switch the ignition on. The SRS lamp should light and then go out; if it stays on, the system has a fault
2Check that the SRS fuses in the engine bay fuse box and in the CEM are intact, without removing or replacing any of them
3With a diagnostic tool, read the SRS module ID. If it reads, the CAN communication is probably fine and the fault may be intermittent
4The CEM should not be replaced for this code, because it shows a communication fault on the CAN network
5The airbag system is safety-critical. Do not work on it or its wiring yourself; have a workshop check the module and wiring

Symptome, die Sie bemerken können1

The SRS warning lamp is lit
