Perimeter Alarm Chime
The perimeter alarm chime warning is used to alert the driver that the perimeter alarm is armed when the driver door is unlocked with a key. The perimeter alarm warning chime is only functional when a key is used to unlock the driver door. If the key fob or keypad (if equipped) is used to unlock the door, 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 driver door is opened and turns off when the perimeter alarm is disarmed (either by using the key fob, keypad or turning the key to the ON position). After the 12 second chime duration, the chime stops sounding and the perimeter alarm activates, sounding the horn and flashing the turn signal lights.
The perimeter alarm chime 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 IPC through the MS-CAN .
