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

Vehicle Speed Signal Circuit between Stereo Component Amplifier and Combination
Meter
DESCRIPTION
The stereo component amplifier assembly receives a vehicle speed signal from
the combination meter assembly to control the ASL function.
HINT:
A voltage of 12 V or 5 V is output from each ECU and then input to the
combination meter assembly. The signal is changed to a pu ...
