Diagnostic Trouble Code (DTC) Information






Diagnostic trouble code (DTC) information CEM-B113187

Condition
The Central Electronic Module (CEM) both transmits and receives information via a standardised serial communication method - LIN (Local Interconnect Network).
The diagnostic trouble code (DTC) is stored if the control module detects that:
- A serious malfunction, e.g., that LIN-communication to Wiper motor module (WMM) is blocked.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Ignition switch position I and II.

Note! The control module can only detect the fault once the test has been started and the diagnostic trouble code (DTC) is stored when the conditions are met.

Substitute value
- None.

Possible source
- Short-circuit between leads in the LIN-net for rain sensor (RSM) and Wiper Motor Module (WMM).
- Open circuit on one of the leads in the LIN-net for rain sensor (RSM) and Wiper Motor Module (WMM).
- Internal error in any unit on the LIN-net for rain sensor (RSM) and Wiper Motor Module (WMM).
- Short circuit may be between leads LIN-net for the Interior movement sensor (IMS), Heartbeat sensor (HBS), and the Siren control module (SCM)
- Open circuit on one of the leads in the LIN-net for movement sensor (IMS), heartbeat sensor (HBS), and Siren control module (SCM).
- Leaking battery acid in Siren control module (SCM) causes interference in the LIN-net.
- Internal error in any unit on the LIN-net for movement sensor (IMS), heartbeat sensor (HBS), and Siren control module (SCM).

Fault symptom[s]
- Windshield wiper does not work
