DIAGNOSIS AND TESTING (Continued)
(1) Check the circuit breaker in the junction block.
If OK, go to Step 2. If not OK, replace the faulty cir-
cuit breaker.
(2) Check the fuse in the Power Distribution Cen-
ter (PDC). If OK, go to Step 3. If not OK, replace the
faulty fuse.
(3) Disconnect and isolate the battery negative
cable. Remove the driver side door trim panel as
described in this group. Check the 12-way Driver
Door Module (DDM) wire harness connector to see
that it is fully seated in the door module receptacle.
If OK, go to Step 4. If not OK, install the wire har-
ness connector properly.
(4) Unplug the 12-way wire harness connector
from the DDM. Check for continuity between the
ground circuit cavity of the DDM wire harness con-
nector and a good ground. There should be continu-
ity. If OK, go to Step 5. If not OK, repair the open
circuit as required.
(5) Connect the battery negative cable. Check for
battery voltage at the fused B(+) circuit cavity of the
DDM wire harness connector. If OK, use a DRB scan
