Toyota Tacoma 2015-2018 Service Manual: Acceleration Sensor Internal Circuit (C1419,C1435)

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.
