Toyota Tacoma (2015-2018) Service Manual: Steering Angle Sensor Internal Circuit (C1433)
DESCRIPTION
Steering angle sensor (spiral cable with sensor sub-assembly) signals are sent to the skid control ECU (master cylinder solenoid) via the CAN communication system. When there is a malfunction in the CAN communication system, it is detected by the steering angle sensor (spiral cable with sensor sub-assembly) zero point malfunction diagnostic function.

CAUTION / NOTICE / HINT
HINT:
- When any of the speed sensors or the yaw rate and acceleration sensor (airbag sensor assembly) has trouble, DTCs for the steering angle sensor (spiral cable with sensor sub-assembly) may be stored even when the steering angle sensor (spiral cable with sensor sub-assembly) is normal. When DTCs for the speed sensors or yaw rate and acceleration sensor (airbag sensor assembly) are output together with DTCs for the steering angle sensor (spiral cable with sensor sub-assembly), inspect and repair the speed sensor and yaw rate and acceleration sensor (airbag sensor assembly) first, and then inspect and repair the steering angle sensor (spiral cable with sensor sub-assembly).

SYSTEM DESCRIPTION
1. DESCRIPTION
The differential system (w/ Differential Lock) directly connects the
rear left and right wheels so that even if one wheel slips while driving
where drive torque transmission is difficult (such as on sand), the drive
torque of the other wheel is ...
