SECURITY Indicator Operation

When you turn the ignition switch to the RUN position, the SECURITY indicator illuminates for approximately 5 seconds. The indicator notifies the driver that the system operates correctly.
The theft deterrent system indicator operates in the following 4 modes:
^ The indicator illuminates when you turn the ignition switch to RUN (5 second bulb check). This condition shows that the indicator and the system operate correctly.
^ The indicator illuminates after the engine starts. This condition indicates that one of the following conditions has occurred:
- The theft deterrent module is not properly programmed. You may use more than one key code value in order to start the vehicle. The improperly programmed module condition usually occurs on a vehicle where the module has been recently replaced.
- The theft deterrent module detected a malfunction in the PASS-Key(R) II system while the engine was running. Verify that the following conditions are met. For further diagnosis, refer to Vehicle Theft Deterrent (VTD) System Check Testing and Inspection
^ The theft deterrent module connections are secure.
^ You are using a good ignition key.
^ The indicator illuminates, but the engine does not start. The theft deterrent module has detected an incorrect key pellet resistance key code value. The system disable functions activate. Perform the following steps:
1. Remove the key from the ignition.
2. Verify that the correct key code (key pellet) is being used in order to start the vehicle. Use a J 35628-A interrogator in order to measure each key pellet for the vehicle. All key codes should match.
3. Wait for approximately 3 minutes for the system disable timer to expire. Use a known good key with the correct key code in order to attempt to restart the engine.
4. If the engine still does not start, refer to Vehicle Theft Deterrent (VTD) System Check Testing and Inspection
^ The indicator flashes and the engine does not start. The theft deterrent module has detected an open or short in the ignition key resistor input circuit. During this mode of operation, the theft deterrent module does not start the system disable timer. Refer to Vehicle Theft Deterrent (VTD) System Check Testing and Inspection
