Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information CEM-B1D3817

Condition
The central electronic module (CEM) communicates with the wiper motor module (WMM). The wiper motor module (WMM) checks the windshield wipers.
The diagnostic trouble code (DTC) is stored if the control module detects that:
- Voltage feed to the Wiper motor module (WMM) is too high.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Control module supplied with power.

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
- The cable for voltage feed is short-circuited to voltage.
- Battery voltage higher than 16 V.

Fault symptom[s]
- Windshield wiper does not work
