Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information CEM-CFF0

Condition
The Central electronic module (CEM) checks the signal from the movement sensor module (MMS) or (IMS) to ensure that it does not have a short-circuit. If the signal has a short-circuit, this can cause abnormally fast discharging of the battery. A DTC is stored if the control module registers that the signal from the movement sensor (MMS) or (IMS) is incorrect. The DTC can be diagnosed at a locking attempt using the remote key.





Substitute value
- None

Possible source
- The signal has a short-circuit to voltage or ground.
