Code U1712 Description

The U1712 code indicates a communication failure between the control module and the Steering Angle Sensor (SAS). The SAS plays a crucial role in providing real-time data regarding the steering wheel's position, which is essential for various vehicle systems, including the Anti-lock Braking System (ABS) and Electronic Stability Program (ESP). When the control module detects a loss of communication or receives invalid data from the SAS, it triggers this diagnostic trouble code. This issue can significantly affect vehicle performance, particularly in terms of handling and stability. If the steering angle data is inaccurate or unavailable, the ABS and ESP systems may not function correctly, leading to compromised vehicle control, especially in adverse driving conditions.

Symptoms of U1712

  1. Engine Light ON (or Service Engine Soon Warning Light)
  2. Erratic or unresponsive steering behavior
  3. Increased difficulty in maintaining vehicle control during turns
  4. Warning messages related to stability control or traction control systems
  5. Potential activation of ABS warning light

How to Fix U1712

  1. Perform a visual inspection of the wiring harness and connectors associated with the steering angle sensor for damage or corrosion.
  2. Check the battery voltage and ensure it is within the manufacturer's specifications to rule out low voltage issues.
  3. Test the steering angle sensor using a multimeter or scan tool to verify its functionality and calibration.
  4. If necessary, recalibrate the steering angle sensor according to the manufacturer's guidelines.
  5. Replace any faulty components, such as the steering angle sensor, wiring harness, or control module, as needed.

Cost to Fix U1712

The cost to diagnose and repair a U1712 code can vary significantly based on the specific issue and the vehicle make and model. Typical parts and labor costs can range from $150 to $600, depending on whether the problem is a simple wiring issue or requires replacement of the steering angle sensor or control module. Labor rates generally vary from $80 to $150 per hour, with dealerships typically charging more than independent shops. It is advisable to get a detailed estimate from a qualified technician to understand the specific costs associated with your vehicle.
