What is C059D?

DTC C059D is a diagnostic trouble code that indicates an issue with the vehicle's steering angle sensor performance, particularly in vehicles equipped with advanced driver-assistance systems (ADAS). This code is commonly found in models like the 2015-2018 Chevrolet Silverado and the 2016-2019 GMC Sierra. When the vehicle’s onboard diagnostic system detects that the steering angle sensor is not functioning correctly or is out of calibration, it triggers this code. The steering angle sensor is crucial for various systems, including stability control, traction control, and adaptive cruise control. If left unresolved, this issue can lead to erratic steering behavior, potentially compromising vehicle safety. Drivers may notice that their vehicle's handling feels off, warning lights illuminate on the dashboard, or they may experience difficulties with features reliant on the sensor's data. It is imperative to address this code promptly to ensure safe vehicle operation and maintain the integrity of safety features. Ignoring this code could lead to increased wear on other components and a more expensive repair down the line.

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

Symptoms

Common symptoms when C059D is present:

  • Check engine light stays on constantly, indicating a persistent issue with the steering system.
  • Steering feels loose or unresponsive, which can affect your control and handling of the vehicle.
  • Adaptive cruise control may malfunction, causing the system to disengage unexpectedly.
  • Stability control warning light may illuminate, suggesting potential issues with vehicle handling.
  • Increased difficulty in making sharp turns or sudden maneuvers, indicating a compromised steering response.

Possible Causes

Most common causes of C059D (ordered by frequency):

  1. The most common cause of DTC C059D is a faulty steering angle sensor, which occurs in approximately 60% of cases. This sensor can become misaligned or damaged due to wear and tear over time.
  2. Another common cause is wiring issues, such as frayed or damaged wires that affect the sensor's ability to communicate with the vehicle's computer. This can be exacerbated by moisture or corrosion.
  3. A third cause could be software glitches in the vehicle's control modules. Keeping your vehicle's software updated can prevent such problems.
  4. Less common but serious causes include issues with the electronic control unit (ECU), which may require extensive diagnostics and potential replacement.
  5. A rare cause might be physical damage to the steering column or related components due to an accident or improper installation during repairs.
