What is C059B?

The diagnostic trouble code (DTC) C059B indicates a malfunction related to the steering angle sensor, which is crucial for the proper operation of the vehicle's stability control system. This code typically appears when the electronic control module (ECM) detects an issue with the sensor’s signal. When the steering angle sensor fails or sends an incorrect signal, it can lead to various problems, including compromised handling and stability, especially during sudden maneuvers or adverse weather conditions. Commonly associated with vehicles like the Chevrolet Silverado (2014-2019), GMC Sierra (2014-2019), and various models from Cadillac and Buick, this issue can manifest as a warning light on the dashboard. If ignored, it could lead to more severe problems, such as potential loss of vehicle control. Drivers experiencing C059B should take immediate action to have their vehicle inspected to avoid compromising vehicle safety.

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

Symptoms

Common symptoms when C059B is present:

  • The warning light on the dashboard illuminates, indicating a problem with the steering system.
  • The vehicle may exhibit erratic or unresponsive steering, making it difficult to control during driving.
  • Drivers might notice the stability control system engaging unexpectedly, causing the vehicle to act inconsistently during turns.
  • In some cases, the cruise control system may become disabled or fail to function properly.
  • A noticeable increase in steering effort may occur, making the vehicle feel heavier during turns.

Possible Causes

Most common causes of C059B (ordered by frequency):

  1. The most common cause of the C059B code is a faulty steering angle sensor, accounting for approximately 60% of cases. This sensor can wear out over time or become misaligned.
  2. Another frequent cause is damaged wiring or connectors related to the sensor, which can lead to intermittent signal loss.
  3. Poor calibration following replacement of the steering angle sensor can also trigger this code. Ensuring proper calibration is crucial for system functionality.
  4. Less commonly, a malfunctioning electronic control module could misinterpret signals from the steering angle sensor, leading to C059B.
  5. In rare instances, mechanical issues within the steering assembly could affect the sensor's operation, requiring a more in-depth inspection.
