Perimeter Alarm Warning Chime

The perimeter alarm warning chime alerts the driver the perimeter alarm is armed when the driver door is unlocked before disarming the alarm. The IPC  displays a perimeter alarm message in the message center and the perimeter alarm warning chime sounds for 12 1-second chime tones when the driver door is opened. The perimeter alarm warning chime turns off when the perimeter alarm is disarmed (either by using the key fob or turning the key to the ON position). After the twelve second warning chime duration, the warning chime stops sounding and the perimeter alarm activates, sounding the horn and flashing the turn signal lamps.

The IPC  receives the perimeter alarm warning chime request from the GWM  over the High Speed Controller Area Network 3 (HS3-CAN).

The GWM  receives the perimeter alarm warning chime request from the BCM  over the High Speed Controller Area Network 1 (HS1-CAN).

When a chime request is received, the IPC  sends the IPC  chime request message to the ACM  and the audio DSP  to sound the chime.
