Checking the unlocking relay circuit

Remove unlocking relay (2/59 (RMI 21)).

Check the wire between 2 in the cable connector and 3 in the relay socket for an open circuit as described in Open-circuit, permanent faults .

Do the necessary corrective action.

If no fault is found, check the resistance between 4 in the relay socket and ground.

The ohmmeter should display 0 ohm.

If the resistance deviates, replace the rear electronic module (REM).
