C13 Checking the Central Locking Motors Windings

- Switch off ignition.




- Unlock trunk/tailgate and all doors.




- Connect an ohmmeter between pos. 87 and pos. 88 on the relay base terminal.
The Ohmmeter should indicate 1 - 15 Ohms.

If the ohmmeter indicates 1 - 15 Ohms:
This reading appears to indicate that the windings in the central locking motors are intact. However an individual central locking motor may still be faulty.
- Continue to C15. C15 Checking Central Locking Windings at Door Posts

If ohmmeter indicates 0 Ohms:
Short circuit in the cable between the central locking motors and the central locking relay base terminal pos. 7 and pos. 88.
- Correct fault or replace cable.
Replace central locking relay D/G.

If the ohmmeter indicates infinite resistance:
