Title: BRAKE CONTROL / DYNAMIC CONTROL SYSTEMS: VEHICLE STABILITY CONTROL SYSTEM: C1433; Steering Angle Sensor Internal Circuit; 2018 - 2020 MY Sienna [11/2017 -        ]

DTC

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 (spiral cable with sensor sub-assembly).

DTC Code

DTC Detection Condition

Trouble Area

C1433

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 cable with sensor sub-assembly)

CAUTION / NOTICE / HINT

HINT:

  • 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 (See page 2018 - 2020 MY Sienna [11/2017 -        ]; BRAKE CONTROL / DYNAMIC CONTROL SYSTEMS: VEHICLE STABILITY CONTROL SYSTEM: U0073,U0100,U0124,U0126; Control Module Communication Bus OFF ).
  • 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 output 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.

REPLACE STEERING ANGLE SENSOR (SPIRAL CABLE WITH SENSOR SUB-ASSEMBLY)

(a) Replace the steering angle sensor (spiral cable with sensor sub-assembly) (See page 2018 - 2020 MY Sienna [11/2017 -        ]; BRAKE CONTROL / DYNAMIC CONTROL SYSTEMS: STEERING ANGLE SENSOR: REMOVAL ).

HINT:

If troubleshooting has been carried out according to Problem Symptoms Table, refer back to the table and proceed to the next step (See page 2018 - 2020 MY Sienna [11/2017 -        ]; BRAKE CONTROL / DYNAMIC CONTROL SYSTEMS: VEHICLE STABILITY CONTROL SYSTEM: PROBLEM SYMPTOMS TABLE ).
