  1. This test diagnoses 2 conditions: warning light is on at all times and warning light never comes on. If warning light is on at all times, go to step 2). Go to step 4) if warning light never comes on.
  2. Open driver's door. Turn ignition off to reset warning. Remove connector from switch. Turn ignition on. Check for warning on message center. Repeat this step for front passenger door and rear doors until no message appears or until all switches are disconnected. If warning still appears, go to step 3). If warning goes out, service last switch that was disconnected.
