What is C035C?

The diagnostic trouble code C035C indicates a problem with the steering angle sensor circuit in vehicles, particularly in models like the 2016-2021 Chevrolet Traverse, GMC Acadia, and Buick Enclave. Essentially, this code means that the vehicle's onboard computer has detected a fault in the communication or functioning of the steering wheel angle sensor, which is crucial for various safety features and stability controls. When this sensor malfunctions, it can lead to erratic handling, decreased steering responsiveness, and potential safety hazards. For instance, if the computer cannot accurately read the steering angle, it may not activate certain electronic stability control systems correctly, leading to compromised vehicle safety. This issue may manifest as a warning light on the dashboard, typically the 'Service Stabilitrak' or 'Check Engine' light, prompting drivers to seek immediate diagnostic attention. Ignoring this code can lead to further complications, such as steering column damage or problems with the traction control system, ultimately resulting in costly repairs. It's essential for car owners experiencing symptoms associated with this code to address it promptly to ensure their vehicle remains safe and operable.

System: C - Chassis (ABS, Steering, Suspension)

Symptoms

Common symptoms when C035C is present:

  • The 'Check Engine' light or 'Service Stabilitrak' indicator remains illuminated on the dashboard, signaling a need for diagnosis.
  • The vehicle may experience erratic steering behavior, making it difficult to maintain a straight path while driving.
  • Drivers may notice a significant decrease in fuel efficiency, with reports of fuel economy dropping by up to 15% due to increased engine load from erratic sensor readings.
  • Loss of traction control functionality, which can lead to slipping or skidding in wet conditions, posing a safety risk.
  • Steering wheel may feel unusually tight or loose, indicating a potential malfunction in the steering system.

Possible Causes

Most common causes of C035C (ordered by frequency):

  1. The most common cause of C035C is a faulty steering angle sensor, which accounts for approximately 60% of cases. Wear and tear or exposure to moisture can compromise sensor functionality.
  2. Electrical issues, such as damaged wiring or poor connections in the sensor circuit, are another common culprit, accounting for about 25% of cases. Corrosion at connectors can disrupt signal transmission.
  3. Software glitches in the vehicle's onboard computer may also trigger this code, and ensuring the vehicle has the latest software updates can mitigate this risk.
  4. Less common but serious causes include a malfunctioning steering column assembly, which may necessitate replacement if damaged.
  5. In rare instances, the problem may originate from other related systems, such as the electronic stability control system, which could complicate diagnostics.
