Replacing the Component

A diagnostic trouble code will be generated if the LED in the rain sensor button is shorted to ground.

If the fault is intermittent it will have been registered earlier but no longer exists. Intermittent faults could be due to interference on starting up or to another type of fault than recurs at different times. The seriousness of the fault is determined from case to case.

Remedy as necessary.
