2. Inspect to determine if one of the following mechanical or electrical concerns apply:






3. If inspection reveals obvious concern(s) that can be readily identified, service as required.

4. NOTE: This diagnostic test quickly provides the capability to identify a short to ground condition for the door lock cylinder switches, hood switch, ignition lock anti-theft switch or the associated circuits.

If the concern(s) remains after the inspection, determine the symptom(s) and go to the Symptom Chart.

Perform the following anti-theft on-board diagnostic test as follows:

^ Turn ignition switch to RUN.

^ If the theft indicator lamp comes on solid for 10 seconds, service the ignition lock anti-theft switch and/or Circuit 936 (DG/W). GO to Pinpoint Test H.

^ Activate power door unlock button 5 times within ten seconds.

^ Count the number of flashes of the anti-theft warning indicator lamp (repeats every 10 seconds). If there is more than one flash, go to anti-theft flash code index. Otherwise, continue to Symptom Chart.

The anti-theft diagnostic mode will automatically cancel after two minutes or by turning ignition switch from RUN to OFF.
