DTC C1434: Steering Angle Sensor Output [04/2018 - 08/2021]: Description
The skid control ECU (brake actuator assembly) receives signals from the steering angle sensor via CAN communication.
HINT:
If there is a malfunction in the bus lines between the steering angle sensor and the CAN communication system, DTC U0126 (Lost Communication With Steering Angle Sensor Module) is output. When U0126 is output together with C1434, inspect and repair the trouble areas indicated by U0126 first.
DTCs may be stored if one of the following occurs:
- Steering angle sensor zero point value malfunction.
- Steering angle sensor signal malfunction.
- Steering angle sensor signal stuck malfunction.
- Steering angle sensor and the yaw rate sensor values inconsistent.
- Steering angle sensor installation abnormality.
