Air Bag Secondary Warning Chime

The air bag secondary warning chime warns that the air bag warning indicator light does not work correctly. The IC  monitors the air bag warning indicator status internally and provides an air bag indication status report to the Restraints Control Module (RCM). When a fault is present in the Supplemental Restraint System (SRS) with the RCM  sending the IC  an air bag warning indicator on request and a fault is detected in the air bag warning indicator, the RCM  sends the IC  a secondary request to sound the air bag warning chime.

The air bag secondary warning chime inputs are the:

• Ignition RUN status.
• Air bag warning indicator request communicated by the RCM  to the IC  over the HS-CAN  .
• Air bag warning indicator chime request communicated by the RCM  to the IC  over the HS-CAN  .
