VEHICLE STABILITY CONTROL SYSTEM, Diagnostic DTC:C1433

DTC Code	DTC Name
C1433	Steering Angle Sensor Internal Circuit

DESCRIPTION

The skid control ECU (brake actuator assembly) outputs this DTC when it receives an internal malfunction signal from the steering angle sensor.

DTC No.	Detection Item	DTC Detection Condition	Trouble Area	Note
C1433	Steering Angle Sensor Internal Circuit	With the +BS terminal voltage 9.5 to 17.4 V, the skid control ECU receives an error signal from the steering angle sensor.	Steering angle sensor (Spiral with sensor cable sub-assembly)	-

WIRING DIAGRAM

Refer to DTC C1432.

CAUTION / NOTICE / HINT

Tech Tips

When U0073, U0124 and/or U0126 is output together with C1433, inspect and repair the trouble areas indicated by U0073, U0124 and/or U0126 first.

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

PROCEDURE

REPLACE SPIRAL WITH SENSOR CABLE SUB-ASSEMBLY

Replace the spiral with sensor cable sub-assembly.

Note

Do not remove the steering angle sensor from the spiral with sensor cable sub-assembly.
When replacing the spiral with sensor cable sub-assembly, confirm that the replacement part is of the correct specification.
