Security Indicator Operation

When the ignition switch is turned to the RUN position, the security indicator illuminates for approximately five seconds, indicating to the driver that the system is operating correctly.

The four bulb control modes for the PASS-Key(R) II system are listed below.

Bulb Stays Illuminated and Engine Starts
If the security indicator stays illuminated after the engine starts, this is an indication that one of the following conditions has occurred:
^ The IPC is not properly programmed, more than one key code value can be used to start the vehicle. The improperly programmed IPC condition usually occurs on a vehicle where the IPC has been recently replaced. Refer to Programming the Instrument Panel Cluster in Instrument Panel Cluster Diagnosis.
^ The IPC detected a malfunction in the PASS-Key(R) II system while the engine was last running. Verify that the IPC connections are secure and that a good ignition key is being used. For further diagnosis, refer to Instrument Panel Cluster Diagnostic System Check in Instrument Panel Cluster Diagnosis.

Bulb Stays Illuminated and Engine Does Not Start
If the security indicator stays illuminated while attempting to start the engine and the engine does not start, the IPC has detected an incorrect key pellet resistance (key code) value and activated the system disable functions. The following actions should be taken:
1. Remove the key from the ignition
2. Verify that the correct key code (key pellet) is being used to start the vehicle. Using J 35628-A, measure each key pellet for the vehicle, all the key codes should match.
3. Wait approximately 3 minutes for the system disable timer to expire, attempt to restart the engine using a known good key with the correct key code.
4. If the engine still won't start, refer to Theft Deterrent System Check.

Bulb Flashes and Engine Does Not Start
If the security indicator flashes and the engine does not start, the IPC has detected an open or short in the ignition key resistor input circuit. During this mode of operation the IPC will not start the system disable timer. Refer to Theft Deterrent System Check.
