Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information CEM-U200187

Condition
Central electronic module (CEM) continuously monitors the systems for adaptive cruise control and brake boost in case of collision risk.
The diagnostic trouble code (DTC) is stored if the control module detects that: The signal from one of the following control modules is missing:
- Forward Sensing Module (FSM).
- Engine control module (ECM).
- Brake control module (BCM).
- Infotainment Control Module (ICM).
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
- None.

Possible source
- Fault-trace in transmitting control module.

Fault symptom[s]
- Collision avoidance driver support; No Functionality
- Adaptive cruise control; No Functionality
