Diagnostic Trouble Code (DTC) Information CEM-B113187

Condition 

The Central Electronic Module (CEM) both transmits and receives information via a standardized 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.

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
