DTC C1433 Steering Angle Sensor Internal Circuit

DESCRIPTION

Steering angle sensor signals are sent to the skid control ECU via the CAN communication system. When there is a malfunction in the CAN communication system, it will be detected by the steering angle sensor zero point malfunction diagnostic function.

DTC Code	DTC Detection Condition	Trouble Area
C1433	When the IG1 terminal voltage is between 10 and 17.4 V, a malfunction signal is received from the steering angle sensor.	Steering angle sensor

INSPECTION PROCEDURE

HINT:

When U0073, U0123, U0124 and/or U0126 is output together with C1433, inspect and repair the trouble areas indicated by U0073, U0123, U0124 and/or U0126 first (COROLLA_ZRE142 RM000000YUO0J7X.html).
When any of the speed sensors or the yaw rate and acceleration sensor has trouble, DTCs for the steering angle sensor may be output even when the steering angle sensor is normal. When DTCs for the speed sensors or yaw rate and acceleration sensor are output together with DTCs for the steering angle sensor, inspect and repair the speed sensor and yaw rate and acceleration sensor first, and then inspect and repair the steering angle sensor.

1.REPLACE STEERING ANGLE SENSOR

Replace the steering angle sensor (COROLLA_ZRE142 RM000002VP1018X.html).
HINT:
If troubleshooting has been carried out according to Problem Symptoms Table, refer back to the table and proceed to the next step (COROLLA_ZRE142 RM000000XHN0DUX.html).
