Key Reminder Switch: Testing and Inspection
DIAGNOSIS AND TESTING - KEY-IN IGNITION SWITCH
WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, REFER TO 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. Disconnect and isolate the battery negative cable. Remove the steering column shrouds. Unplug the key-in ignition switch wire harness connector
from the ignition switch.
2. Check for continuity between the key-in switch sense circuit and the left front door jamb switch sense circuit terminals of the key-in ignition
switch. There should be continuity with the key in the ignition lock cylinder, and no continuity with the key removed from the ignition lock
cylinder. If OK, go to Step 3. If not OK, replace the faulty ignition switch assembly.
3. Check for continuity between the left front door jamb switch sense circuit cavity of the key-in ignition switch wire harness connector and a good
ground. There should be continuity with the driver door open, and no continuity with the driver door closed. If OK, see the diagnosis for
Instrument Cluster. If not OK, repair the circuit to the driver door jamb switch as required.
