Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information CEM-B1D3816

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 low.
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
- Contact resistance or oxidation in the terminals or connections.
- Short-circuit to ground in the power supply cable.
- Battery voltage too low.

Fault symptom[s]
