Replacing Wiper Motor Module (WMM)

The central electronic module (CEM) has detected that the wiper motor module (WMM) has an internal fault.

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 wiper motor module (WMM) or may be a different type of fault which occurs on different occasions. The fault is evaluated depending on how it occurs. Replace the wiper motor module (WMM) if the fault recurs.

Replace the wiper motor module (WMM) in the event of a permanent fault.

Remedy as necessary.
