Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information CEM-B10E712

Condition
Central electronic module (CEM) checks output signal to relay ignition on.
The diagnostic trouble code (DTC) is stored if the control module detects that:
- The output to the relay winding is short-circuited to voltage.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Activation of relay.

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 supply voltage in the cable.

Fault symptom[s]
- Engine fails to start
