Signal Too High. Permanent Fault

Signal too high. Permanent fault

Checking/replacing the component
Replace relay, 2/117.
Activate relay with button from control panel on RH rear door, window up.
If the function is now OK, this means that the fault was probably caused by a faulty relay (short circuit in the relay).

Additional information

Was the function OK?

Yes - Fault Found

No - Checking the control unit

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

Checking the control unit
Remove window lift relay 2/117 from CEM socket.
Check the relay coil driver circuit for a short circuit to voltage supply by checking the voltage between #2 and ground in the relay socket to relay 2/117.
For additional information regarding short circuits to voltage supply, see Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault.

Hint: The voltage between #2 and ground should be approximately 0 volt. If the voltmeter indicates an incorrect value, the control unit must be replaced.
