Signal Too High. Permanent Fault

Signal too high. Permanent fault

Checking the relay and supply
Check that relay 2/90 is correctly connected. Check that the relay is not defective.

Hint: This tip applies only in the event of an open-circuit in cable.
The fault may have been caused by an open-circuit in the supply to the relay. The voltage must be 12 V at terminal #1 for relay 2/90. Check fuse 11B/13 in particular.

Remedy as necessary.

Other information:
- For further information about the fuses and relays, see the Wiring Diagram.









Was a fault detected?

Yes - Verification

No - Checking the cable

Checking the cable




- Ignition off.
Check the cable between central electronic module (CEM) terminal #14A and windshield wiper relay 2/90 terminal #2. Check for a short-circuit to supply voltage.
Also check the connector. Check for a short-circuit to supply voltage.
Remedy as necessary.
