Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information CEM-B114711

Condition
The central electronic module (CEM) monitors the supply voltage to the left-hand front fog lamp.
The diagnostic trouble code (DTC) is stored if the control module detects that:
- Signal too low on the output.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Activated fog lamp.

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 (the output) turns off during the driving cycle when fault is detected. The function (the output) switches off permanently after 100 operating cycles where the fault was detected. Erasing trouble codes as well as start of new driving cycle resets the output.

Possible source
- Contact resistance, oxidation or poor contact in connections.
- The signal cable is short-circuited to ground.

Fault symptom[s]
- Front fog lights/daytime running lights/Does not work
