Checking the locking relay circuit

Remove the locking relay (2/58 (RMI 20)).

Check the cable between terminal #2 the cable and connector and terminal #3 on the relay base. Check for an open-circuit.

Remedy as necessary.

If no fault is detected, measure the resistance between terminal #4 in the relay base and ground.

The ohmmeter should read 0 ohm.

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