Security Indicator Fails To Light During Bulb Test

WARNING: This page is about a different car, the 2004 Dodge Dakota. However, it is still accessible from the selected car via links, so may be relevant.

If the security 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. (Refer to ACTUATOR TEST ). If the security 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. Refer to SYSTEM WIRING DIAGRAMS .

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. Refer to ELECTRONIC CONTROL MODULES .
  1. Check the fused B(+) fuse in the Junction Block (JB). If OK, go to Step 2. If not OK, repair the shorted circuit or component as required and replace the faulty fuse.
  2. Check for battery voltage at the fused B(+) fuse in the JB. If OK, go to Step 3. If not OK, repair the)pen B(+) circuit between the JB fuse and the Power Distribution Center (PDC) as required.
  3. Check the fused ignition switch output (run-start) fuse in the JB. If OK, go to Step 4. If not OK, repair the shorted circuit or component as required and replace the faulty fuse.
  4. Turn the ignition switch to the On position. Check for battery voltage at the fused ignition switch output (run-start) fuse in the JB. If OK, go to Step 5. If not OK, repair the open fused ignition switch output (run-start) circuit between the JB and the ignition switch as required.
  5. Disconnect and isolate the battery negative cable. Disconnect the instrument panel wire harness connector for the Sentry Key Immobilizer Module (SKIM) from the SKIM connector receptacle. Check for continuity between the ground circuit cavity of the instrument panel wire harness connector for the SKIM and a good ground. There should be continuity. If OK, go to Step 6. If not OK, repair the open ground circuit to ground as required.
  6. 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 Step 7, If not OK, repair the open fused B(+) circuit between the SKIM and the JB as required.
  7. 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, refer to ELECTRONIC CONTROL MODULES and 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 fuse as required.
