Signal Too High. Permanent Fault

Signal too high. Permanent fault

Checking the relay and supply
Check that relay 2/92 is correctly connected. Check that the relay is not defective.
The following applies only to CEM-8F2B.

Hint: The fault may have been caused by an open-circuit in the supply to the relay. The voltage must be 12 V at both terminals #1 and #5 for relay 2/92. Check fuse 11B/16 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 #16A and washer motor relay terminal #2 (2/92). Check for a short-circuit to supply voltage (for CEM8F29). Check for an open-circuit.
Also check the connector for a short-circuit to supply voltage and an open-circuit.
Remedy as necessary.

Fault-tracing information
The fault should have been detected and remedied. As this is not the case fault-tracing has failed.
Exit fault-tracing for this diagnostic trouble code (DTC) or make another attempt.
