Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information CEM-B113D14

Condition
The central electronic module (CEM) communicates with the sun roof module (SRM).
Central electronic module (CEM) controls the function global / closing of window and sunroof. Central electronic module (CEM) sends request for global opening/closing of sunroof via directly connected signal cable to Sun roof module (SRM).
The diagnostic trouble code (DTC) is stored if the control module detects that:
- Signal too low from the output.
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
- The function switches off permanently after 100 operating cycles where the fault was detected. Erasing diagnostic trouble codes (DTCs) resets the result.

Possible source
- Short-circuit to ground in the cable.
- Open circuit on signal cable.

Fault symptom[s]
- Power sun roof not working
