Air Bag Secondary Warning Chime

The air bag secondary warning chime warns the air bag warning indicator LED  is inoperative. The air bag secondary warning chime sounds through the front speakers. If the IPC  detects a fault with the air bag warning indicator LED  during the bulb prove out, the air bag secondary warning chime sounds. If the IPC  detects a fault in the air bag warning indicator when a SRS  fault condition exists and the RCM  has sent the IPC  the air bag indicator request, the air bag secondary warning chime sounds. The air bag chime is a 0.5-second chime that sounds 5 times.

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