Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information

Condition
The control modules communicate with each other in a network via a standardized serial communication procedure - CAN (Controller Area Network) - to exchange information. The diagnostic trouble code (DTC) is generated if the engine control module (ECM) registers that the software does not correspond with the other vehicle configurations, which results in the engine control module (ECM) being unable communicate with the other control modules.

Substitute value
- CAN communication is disabled

Possible source
- faulty software in the engine control module (ECM)
- damaged control module.
- This diagnostic trouble code is generated in combination with other trouble codes. Information on the possible root cause is described.

Fault symptom[s]
- electronic throttle system (ETS) warning lamp lit.
- The cruise control does not function at all
- The engine judders under acceleration
- The engine judders heavily after engine braking
