DTC C1A47: Steering Angle Sensor [04/2013 - 10/2016]: Description

The brake actuator assembly (skid control ECU) receives steering rotation angle information from the spiral with sensor cable sub-assembly (steering angle sensor), and sends the information to the driving support ECU assembly via CAN communication.

If the brake actuator assembly (skid control ECU) detects a malfunction of the spiral with sensor cable sub-assembly (steering angle sensor), it sends a malfunction signal to the driving support ECU assembly and stores this DTC.
