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 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

). - 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 SPIRAL CABLE WITH SENSOR SUB-ASSEMBLY |
(a) Replace the spiral cable with sensor sub-assembly (See page
).
NOTICE:
- Do not remove the steering angle sensor from the spiral cable with sensor sub-assembly.
- When replacing the spiral cable with sensor sub-assembly, confirm that the replacement part is of the correct specification.
HINT:
If troubleshooting has been carried out according to the Problem Symptoms Table,
refer back to the table and proceed to the next step (See page
