Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information CEM-B100A15

Condition
The central electronic module (CEM) checks the voltage in the supply cable to the fuel pump (FP).
The diagnostic trouble code (DTC) is stored if the control module detects that:
- The signal cable has an open circuit or is short-circuited to voltage.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Ignition switch position I and II.

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
- Short-circuit to battery voltage in the signal cable.
- Open-circuit in signal cable to the fuel pump (FP).

Fault symptom[s]
- Starting/Engine does not start/Unsure when/at all times
