• Ignition off.

  Check that fuse F4 in the engine compartment fusebox is intact. If the fuse is blown, check the circuit after the fuse. Check for a short-circuit to ground.

  Check that the fuse for the driver door module (DDM) in the central electronic module (CEM) is intact. If the fuse is blown, check the circuit after the fuse. Check for a short-circuit to ground.

  Connect a voltmeter between the output on central electronic module (CEM) terminal (#C31) (#31) and ground (the supply for the driver door module (DDM)).

  With the ignition off the voltage between the output and ground should be battery voltage.

  NOTE:

  The reading can be taken on the reverse of the connector on the central electronic module (CEM). However, the central electronic module (CEM) must first be disconnected. Take care not to damage the terminals. If the reading cannot be taken in this way, connect the adapter wiring.

  Check the cable between the driver door module (DDM) and ground. Check for an open-circuit.
