Code C1A47 Lexus Description
For vehicles with Lane Departure Alert System (W/ Steering Control): The Forward Recognition Camera receives steering angle information from the Steering Angle Sensor. If the forward recognition camera detects a Steering Angle Sensor malfunction, Diagnostic Trouble Code (DTC) C1A47 is stored.
For vehicles with Pre-collision System: The Skid Control ECU (Brake Actuator Assembly) 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 Skid Control ECU (Brake Actuator Assembly) 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.
