Security Lamp/Indicator: Testing and Inspection
The diagnosis found here addresses an inoperative Smart Key Immobilizer System (SKIS) indicator lamp condition. If the SKIS indicator lamp flashes
with the ignition switch in the On position, refer to Accessories and Optional Equipment/Antitheft and Alarm Systems for diagnosis.
WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, REFER TO AIRBAGS 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.
If the SKIS indicator lamp fails to light when the ignition switch is turned to the On position, replace the SKIS indicator lamp bulb with a known good
unit. If the SKIS indicator lamp still fails to operate, further diagnosis of the SKIS indicator lamp and the instrument cluster circuitry should be
performed as described in Instrument Cluster. If the SKIS indicator lamp and instrument cluster circuitry are OK, diagnosis of the Smart Key
Immobilizer System and the CCD data bus should be performed with a DRB scan tool as described in the proper Diagnostic Procedures.
