DESCRIPTION
The skid control ECU (master cylinder solenoid) receives signals from the yaw rate and acceleration (airbag sensor assembly) via the CAN communication system.
The airbag sensor assembly has a built-in yaw rate and acceleration sensor and detects the vehicle's condition using 2 circuits (GL1, GL2).
If there is trouble in the bus lines between the yaw rate and acceleration sensor (airbag sensor assembly) and the CAN communication system, DTCs U0123 (yaw rate sensor communication trouble) and U0124 (acceleration sensor communication trouble) are stored.
These DTCs are also output when calibration has not been completed.

The distance control switch is used to set the distance for vehicle-to-vehicle
distance control mode. The distance control switch is installed in the steering
pad switch assembly. The vehicle-to-vehicle distance set value can be changed by
operating the steering pad switch assembl ...
Driver Side Seat Belt Warning Light does not Operate
DESCRIPTION
When the ignition switch is ON, the airbag sensor assembly transmits front seat
inner belt status signals to the combination meter assembly through CAN. If the
driver seat belt is not fastened, the combination meter assembly blinks the driver
side seat belt warning light. If the s ...
