C1A47 Toyota Code - Steering Angle Sensor
Quick Answer
For vehicles with Blind Spot Monitor System: The Blind Spot Monitor Sensor receives steering angle signals from the Steering Angle Sensor via Controller Area Network (CAN) communication. Common causes include Faulty Vehicle Stability Control System, Faulty Skid Control ECU (Brake Actuator Assembly), Faulty Driving Support ECU Assembly. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code C1A47 Toyota 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.
What are the Possible Causes of the DTC C1A47 Toyota?
- Faulty Vehicle Stability Control System
- Faulty Skid Control ECU (Brake Actuator Assembly)
- Faulty Driving Support ECU Assembly
For vehicles with Blind Spot Monitor System: - Steering Sensor
- Blind Spot Monitor Sensor Left (LH)
- Blind Spot Monitor Sensor Right (RH)
