Toyota RAV4 Service Manual: Driver side seat belt warning light does not operate
Description
When the ignition switch is on, the center airbag sensor transmits front seat inner belt status signals to the combination meter through the can bus line. If the driver seat belt is not fastened, the combination meter blinks the driver side seat belt warning light. If the seat belt is fastened, the warning light goes off.
Notice:
The seat belt warning system uses the can bus line. 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.
