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.

Hint: After carrying out the repair, check that the fault has been remedied.








- Ignition off
- Reinstall the connectors, components etc.
- Ignition on
Activate the rain sensor.

Hint: When the rain sensor is activated the wiper blades perform a reference sweep to determine the cleanness/condition of the windscreen. Switching off the ignition deactivates the rain sensor. To activate the rain sensor, switch on the ignition, move the lever to position 0 and then to the intermittent wipe position.

Check that the LED in the rain sensor button comes on.
