Checking the power supply

Remove the relay for unlocking 2/67 (RMI 20) from the integrated relay / fusebox in the cargo compartment.

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

If a fault is detected, check in particular the intermediate connector in the cable harness. Check for contact resistance and oxidation.

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

In both cases the ohmmeter should read 0 ohms.

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