Security Lamp/Indicator: Description and Operation

SECURITY INDICATOR

The IPC illuminates the SECURITY indicator as determined by the vehicle theft deterrent (VTD) system and the content theft deterrent (CTD) system. The IPC receives a class 2 message from the rear integration module (RIM) or the theft deterrent control module requesting illumination.
- The VTD system requests the IPC to illuminate the indicator only when the ignition switch is ON. The VTD system uses the indicator in order to identify system status.
- The IPC detects a loss of class 2 communications with either the RIM or the theft deterrent control module.
- The IPC performs the displays test at the start of each ignition cycle. The indicator illuminates for approximately 5 seconds.

The content theft deterrent (CTD) system uses the security indicator as a status indicator. The rear integration module (RIM) commands the instrument panel cluster (IPC) to illuminated the security indicator on steady or to flash the security indicator only when the ignition switch is in the off position via the class 2 serial data circuit. The security indicator will be requested to flash or to be illuminated on steady under the following conditions:
- The RIM will command the IPC to flash the security indicator when either front door is open.
- The RIM will command the IPC to illuminated the security indicator on steady when either front door is open and the doors are locked by the power door lock switch or a lock command from the keyless entry system.
