Signal Too High. Permanent Fault

Signal too high. Permanent fault

Replacing the component
Replace relay, 2/67.
Activate relay.
If the function is now OK, this means that the fault was caused by a faulty relay (short circuit in the relay).

Additional information:
- To access the relay/fuse box in the boot, see Integrated relay/fusebox cargo compartment/Rear electronic module (REM), replacing Integrated Relay/Fusebox Cargo Compartment/Rear Electronic Module (REM), Replacing.









Does it work?

Yes - FAULT FOUND

No - Checking the wires

-------------------------------------------------

Checking the wires
- Remove the relay.
Check relay coil driver for a short circuit to voltage supply by checking the voltage on 2 in the relay socket.
For additional information regarding a short circuit to voltage supply, see Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault.

Hint: The voltage between 2 and ground must be approximately 0 V.








If the voltmeter indicates an incorrect value, the control unit should be replaced.

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








- Ignition off.
- Reinstall the connectors, components etc.

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.

Do you want to exit fault-tracing?
