Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information SWM-DD00

Condition




The control modules communicate with each other in a network via a standardized serial communication interface - LIN (Local Interconnect Network) - to exchange information.
The control modules transmit and receive information. The diagnostic trouble code (DTC) is stored if the steering wheel module (SWM) registers that the communication is disrupted or disabled.

Note! In the event of a system communication fault it is not possible to communicate with the steering wheel module (SWM). Therefore it will only be possible to read off the diagnostic trouble code (DTC) if the fault is intermittent.

The diagnostic trouble code (DTC) can be diagnosed when the ignition is switched on.

Substitute value
- The cruise control will be disabled until the next correct signal is received.

Possible source
- Communication problems.

Fault symptom[s]
- Cruise control does not function at all.
