The secondary air bag warning chime is an audible chime located in and controlled by the IPC. If a fault is detected with the air bag warning indicator, a DTC will be stored in memory of the IPC. Upon receiving the message from the RCM that a SRS fault has been detected, the IPC will sound the secondary air bag warning chime in a pattern of 5 sets of 5 beeps.
