Signal too high

Checking and replacing the component
Replace the relay, 2/115.
Activate the relay.
If the function is OK, the cause of the fault was a defective relay (short-circuit in the relay).

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









Was the function OK?

Yes - Fault Found

No - Checking the control module

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

Checking the control module
- Remove the relay.
Check the relay coil driver circuit for a short-circuit to supply voltage by measuring the voltage at terminal #2 in the relay base.

Hint: The voltage between terminal #2 and ground should be approximately 0 V.

Replace the control module if the voltmeter displays an incorrect value.
