Skis Indicator Fails To Light During Bulb Test

WARNING: This page is about a different car, the 2002 Jeep Liberty. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: The following tests may not prove conclusive in the diagnosis of this system. The most reliable, efficient, and accurate means to diagnose the Sentry Key Immobilizer System requires the use of a DRBIII(R) scan tool.

If the Sentry Key Immobilizer System (SKIS) indicator in the instrument cluster fails to illuminate for about three seconds after the ignition switch is turned to the On position (bulb test), perform the instrument cluster actuator test. See ACTUATOR TEST in ANALOG INSTRUMENT PANELS - LIBERTY article. If the SKIS indicator still fails to light during the bulb test, a wiring problem resulting in the loss of battery current or ground to the Sentry Key Immobilizer Module (SKIM) should be suspected, and the following procedure should be used for diagnosis.

Check the fused B+ fuse (Fuse No. 33, 10 amp) in the Junction Block (JB). If OK, go to next step. If not OK, repair the shorted circuit or component as required and replace the faulty fuse.
Check for battery voltage at the fused B+ fuse (Fuse No. 33, 10 amp) in the JB If OK go to next step. If not OK, repair the open B+ circuit between the JB and the battery as required.
Check the fused ignition switch output (run-start) fuse (Fuse No. 15, 10 amp) in the JB. If OK, go to next step. If not OK, repair the shorted circuit or component as required and replace the faulty fuse.
Turn the ignition switch to the On position. Check for battery voltage at the fused ignition switch output (run-start) fuse (Fuse No. 15, 10 amp) in the JB. If OK, go to next step. If not OK, repair the open fused ignition switch as required.
Disconnect and isolate the battery negative cable. Disconnect the instrument panel wire harness connector for the Sentry Immobilizer Module (SKIM) from the SKIM connector receptacle. Check for continuity between each of the two ground circuit cavities of the instrument panel wire harness connector for the SKIM and a good ground. There should be continuity. If OK, go to next step. If not OK, repair the open ground circuit(s) to ground (G202) as required.
Reconnect the battery negative cable. Check for battery voltage at the fused B+ circuit cavity of the instrument panel wire harness connector for the SKIM. If OK, go to next step. If not OK, repair the open fused B+ circuit between the SKIM and the JB as required.
Turn the ignition switch to the On position. Check for battery voltage at the fused ignition switch output (run-start) circuit cavity of the instrument panel wire harness connector for the SKIM. If OK, use a DRBIII(R) scan tool to complete the diagnosis of the SKIS. If not OK, repair the open fused ignition switch output (run-start) circuit between the SKIM and the JB as required.
