Title: BRAKE CONTROL: VEHICLE STABILITY CONTROL SYSTEM (for Hydraulic Brake Booster): C1433; Steering
Angle Sensor Internal Circuit; 2016 MY Tacoma [08/2015 - ]
DTC C1433 Steering Angle Sensor Internal Circuit
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.
DTC
CODE
DTC DETECTION CONDITION TROUBLE AREA
C1433
Either condition is met:
With the IG1 terminal voltage at 9.5 to 17.4 V, the skid
control ECU (master cylinder solenoid) receives an error
signal from the steering angle sensor for 0.012 seconds.
1.
An open in the sensor power supply circuit for 1 second or
more.
2.
Steering angle sensor (spiral
cable with sensor
sub-assembly)
WIRING DIAGRAM
Refer to DTC C1432 .
INSPECTION PROCEDURE
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).
PROCEDURE
1. CHECK CAN COMMUNICATION SYSTEM
(a) Check for DTCs .
