The DDM is an integral part of the vehi cle security system. In conjunction with the BPM and SLCM via the SCP network, it
controls door locking, interior lighting, door window position and door mirror position. The DDM also provides an interface
via the SCP network, between the driver door switchpack and all door control modules which permits remote control of all
door window positions.

Diagnosis and Testing
Tests Using the Portable Diagnostic Unit
Refer to PDU User Guide
The complexity of the electronics involved with the various Electronic Control Modules and the multiplexed communication
networks, preclude the use of workshop general electrical test equipment. Therefore, reference should be made to the PDU
User Guide for detailed instructions on test ing control modules.
The PDU systematically test s and analyses the control modules and th e associated electrical connections.
Where a fault involving a control module is indicated by the PDU, before replacing the component, some basic diagnostic
methods may be necessary to confirm that connecti ons are good and that wiring is not damaged.
