Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information DEM-U210000

Condition
The Differential electronic module (DEM) monitors the information that comes from other control modules. The Central electronic module (CEM) informs about the vehicle's configuration, among other things.
The diagnostic trouble code (DTC) is stored if the control module detects that:
- Vehicle configuration from central electronic module (CEM) is lost.
- Incorrect value lasts longer than 30 seconds.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Ignition on.

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
- Open-circuit in the control area network (CAN).
- Fault-trace the central electronic module (CEM).

Fault symptom[s]
- None.
