Test A: The Safety Belt Warning Chime Is Inoperative

PINPOINT TEST A: THE SAFETY BELT WARNING CHIME IS INOPERATIVE

A1-A6:

Normal Operation
The seat belt tone request is transmitted over the controller area network (CAN) to the cluster from the restraint control module (RCM). The safety belt switches are hard-wired to the RCM. When the RCM detects a safety belt switch that is not buckled, the instrument cluster sends a tone request to the GEM which sounds the chime.

Possible Causes
- GEM
- RCM
- instrument cluster
