Air Bag Secondary Warning Chime

The air bag secondary warning chime warns that the air bag warning indicator LED is inoperative. 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.
