Security Indicator Operation - Oldsmobile 1998 Eighty-Eight V6-3.8L VIN K Service Manual

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

The four indicator control modes for the PASS-Key(R) II system are listed below:
^ Indicator Illuminates When the Ignition Switch is Turned to RUN (5 second bulb check), this indicates that the indicator and system are operating correctly.
^ Indicator Illuminates After the 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 PASS-Key(R) II theft deterrent module is not properly programmed, more than one key code value can be used to start the vehicle. The improperly programmed module condition usually occurs on a vehicle where the module has been recently replaced.
- The PASS-Key� II theft deterrent module detected a malfunction in the PASS-Key(R) II system while the engine was running. Verify that the PASS-Key(R) II theft deterrent module connections are secure and that a good ignition key is being used. For further diagnosis, refer to the Theft Deterrent System Check.
^ Indicator is Illuminated and the Engine does not Start, if the SECURITY indicator stays illuminated while attempting to start the engine and the engine does not start, the PASS-Key(R) II theft deterrent module 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 a 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.
^ Indicator Flashes and the Engine does not Start, if the SECURITY indicator flashes and the engine does not start, the PASS-Key(R) II theft deterrent module has detected an open or short in the ignition key resistor input circuit. During this mode of operation the PASS-Key(R) II theft deterrent module does not start the system disable timer. Refer to the Theft Deterrent System Check.
