Replacing Component

The central electronic module (CEM) has detected that the rain sensor module (RSM) 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 rain sensor module (RSM) or may be a different type of fault which occurs on different occasions. The fault is evaluated depending on how it occurs. If the fault recurs, replace the rain sensor module (RSM).

If the fault is permanent, replace the rain sensor module (RSM).

Remedy as necessary.
