Perimeter Alarm Warning Chime
The perimeter alarm warning chime is used to alert the driver that the perimeter alarm is armed when the driver door is unlocked and opened using a key. The perimeter alarm warning chime is only functional when a key is used to unlock the driver door. If the key fob is used to unlock the doors, the perimeter alarm is disarmed and the perimeter alarm warning chime does not sound. The perimeter alarm warning chime sounds for 12 seconds when the key and the driver door is used to unlock the vehicle and turns off when the perimeter alarm is disarmed (either by using the key FOB or turning the ignition to the ON position). After the 12 second chime duration, the perimeter alarm chime stops sounding and the perimeter alarm activates, sounding the horn and flashing the turn signal lights.
The perimeter alarm inputs are:
- Ignition state
- Passive Anti-Theft System (PATS) armed/disarmed status
- Driver door ajar input to the SJB
- Perimeter alarm chime request from the SJB to the IC through the MS-CAN
