DESCRIPTION

When the driver seat belt is not fastened with the ignition switch ON, the driver seat belt warning light on the combination meter assembly comes on to inform the driver. The center airbag assembly detects the driver seat belt status and sends signals to the combination meter assembly using CAN.

NOTICE:
The seat belt warning system uses CAN. Before troubleshooting the seat belt warning system, perform "COMMUNICATION FUNCTION CHECK" by following "HOW TO PROCEED WITH TROUBLESHOOTING" to confirm that the communication systems are normal.
