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 Instrument Cluster (IPC) is not properly programmed. More than 1 key code value can be used in order to start the vehicle. The improperly programmed IPC condition usually occurs on a vehicle with a recently replaced IPC.
^ The IPC detected a malfunction in the PASS-Key(R)II system while the engine was last running. Verify that the IPC conditions are secure and that a good ignition key is being used. For further diagnosis, refer to A Diagnostic System Check - Instrument Cluster in Instrument Panel, Gauges and Console. Testing and Inspection
