Signal Too High. Intermittent Fault

Signal too high. Intermittent fault

Checking cable

Hint: The fault could also have been caused by the windshield wipers sticking.

Check the cable between central electronic module (CEM) terminal #16B and windshield wiper motor (6/1) terminal #3. Check the cable between central electronic module (CEM) terminal #16B and rain sensor (7/149) terminal #4.
Check for an intermittent short-circuit to supply voltage or for intermittent contact resistance and oxidation. Check for loose connections.
Check the connector.
Remedy as necessary.
