Replacing The Control Module
The steering wheel module (SWM) has registered that the signal is missing or faulty in the communication with other control modules.
HINT: In the event of communication problems, the fault may exist in other parts of the communications network. The role of the central electronic module (CEM) is to control the communications network and to store diagnostic trouble codes (DTCs) in the event of communication problems between control modules.
If the fault is intermittent, it has been registered previously but is no longer present. Intermittent faults can be caused by interference at start up of the steering wheel module (SWM) or may be a different type of fault which occurs on different occasions. The fault is evaluated depending on how it occurs. Replace the steering wheel module (SWM) if the fault recurs.
Replace the steering wheel module (SWM) in the event of a permanent fault.
Remedy as necessary.
