Communication Problems With the Differential Electronic Module (DEM)

Communication problems with the differential electronic module (DEM)

Checking diagnostic trouble codes (DTCs) in the central electronic module




Checking diagnostic trouble codes (DTCs) in the central electronic module

Checking other diagnostic trouble codes (DTCs)
In the event of communication problems, the fault may exist in other parts of the communications network.
The role of the central electronic module is to generally control the communications network and to store diagnostic trouble codes (DTCs) in the event of communication problems between control modules.
If there are diagnostic trouble codes (DTCs) stored for communication problems in the central electronic module, stop the fault tracing and fault trace the central electronic module.

Were diagnostic trouble codes (DTCs) for communication problems stored in the central electronic module?

Yes - DONE

No - No Fault Found
