SRS-E001

Condition







The control modules transmit and receive information via a standardized serial communication method  CAN (Controller Area Network). The diagnostic trouble code (DTC) is stored if the control module registers serious interference (CAN communication blocked).

NOTE: In the event of system communication problems, it is not possible to communicate with the control module. Therefore it will only be possible to read off the fault if it is intermittent.

Substitute value

The control module shuts itself off ("bus-off").

Hint: The control module will remain shut off until the power supply is broken (15, 30, X). When the power supply is connected the control module will make a new attempt to communicate.

Possible source

- Short-circuit between the control area network (CAN) wiring.
- Open-circuit in the control area network (CAN) wiring.
- Internal fault in the control module.
- Internal fault in another control module in the same part of the control area network (CAN).

Fault symptom[s]

- The SRS indicator lamp is lit.
