DTC C1434: Steering Angle Sensor Output Malfunction [08/2015 - ]: Description

The skid control ECU receives signals from the steering angle sensor via the CAN communication system.

HINT:

If there is trouble 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.

DTC No.	DTC Detection Condition	Trouble Area
C1434	Any of the following is detected: The difference between zero point stored in the steering angle sensor and the estimated zero point exceeds 15 deg. The offset value of the steering angle sensor is -13.5 deg. or less or 13.5 deg. or more. The steering angle sensor value exceeds a specified value for 0.3 seconds or more. The change of the steering angle sensor value within 0.02 seconds is abnormal. The steering angle sensor value changes by less than 5 deg. and both left and right turns have been recognized. There is a difference between the skid control ECU estimated value and the steering angle sensor value due to an abnormal steering angle sensor value.
