WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, REFER TO GROUP 8M - PASSIVE RESTRAINT SYSTEMS BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE. FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY.

(1) Rotate the headlamp switch knob counterclockwise to ensure that the dome lamps are not switched off. Open the driver door and note whether the interior lamps light. They should light. If OK, see Key-In Ignition Switch and/or Headlamp Switch in the Diagnosis and Testing section of this group. If not OK, go to Step 2.

(2) Disconnect and isolate the battery negative cable. Unplug the driver door latch wire harness connector.

Check for continuity between the ground circuit cavity in the body half of the driver door latch wire harness connector and a good ground. There should be continuity. If OK, go to Step 3. If not OK, repair the circuit to ground as required.

(3) Check for continuity between the driver door ajar switch ground circuit terminal and the driver door ajar switch sense circuit terminal of the driver door latch wire harness connector. There should be continuity with the driver door open, and no continuity with the driver door closed. If OK, go to Step 4. If not OK, replace the faulty latch.

(4) Remove the Central Timer Module (CTM) from its mounting bracket to access the CTM wire harness connectors. Refer to Central Timer Module in the Removal and Installation section of Group 8E - Instrument Panel Systems for the procedures.

Unplug the 14-way CTM wire harness connector.

Check for continuity between the driver door ajar switch sense circuit cavity of the 14-way CTM wire harness connector and a good ground. There should be no continuity. If OK, go to Step 5. If not OK, repair the short circuit as required.

(5) Check for continuity between the driver door ajar switch sense circuit cavities of the 14-way CTM wire harness connector and the driver door latch wire harness connector. There should be continuity. If OK, see Key-In Ignition Switch and/or Headlamp Switch in the Diagnosis and Testing section of this group. If not OK, repair the open circuit as required.
