General Description

The theft deterrent system on this vehicle consists of the following two separate systems:
^ The Personal Automotive Security System (PASS-Key(R) II)
^ The Content Theft Deterrent (CTD) System.

These systems are described and diagnosed separately within this section.
The PASS-Key(R) II s designed to help prevent vehicle theft. The PASS-Key(R) II disables the engine unless the driver uses a key with a specific electrical resistance in the ignition switch. The system consists of the following components:
^ The ignition key
^ The steering column (ignition) lock cylinder
^ The instrument cluster (SECURITY indicator)
^ The PASS-Key(R) II theft deterrent module
^ The Park/Neutral Position (PNP) switch
^ The theft deterrent relay
^ The powertrain control module (PCM)

The Content Theft Deterrent (CTD) system is designed to provide a warning in the event of a forced entry. The attempted forced entry may come through the doors. When a forced entry is attempted, the alarm warning system activates. The warning system causes the following actions to occur:
^ The horns sound intermittently.
^ The exterior lights flash in unison for approximately 3 minutes.

The CTD system consists of the following components:
^ The door lock actuator switches
^ The door lock cylinder switches
^ The door tamper switches (Buick)
^ The instrument cluster (SECURITY indicator)
^ The lamp control module (LCM)
^ The rear compartment lid tamper switch
^ The remote function actuator (RFA) module

The yellow SECURITY indicator in the instrument cluster is controlled by both the following systems:
^ In the PASS-Key(R) II system, the theft deterrent module controls the indicator only when the ignition switch is in RUN or START.
^ In the CTD system, the remote function actuator (RFA) module controls the indicator only when the ignition switch is OFF.

If the engine cranks but does not start, the PASS-Key(R) II system is not causing the problem. The content theft deterrent system does not affect the engine starting.
