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.

Steering Angle Sensor Initialization Incomplete (C1439,C1445)
DESCRIPTION
The skid control ECU (brake actuator assembly) acquires steering angle sensor
zero point every time the ignition switch is turned ON and the vehicle is driven
at 35 km/h (22 mph) or more for approximately 5 seconds. The ECU also stores the
previous zero point.
The steering angle ...
