To diagnose C0598 using the GeekOBD APP, start by connecting the app to your vehicle's OBD2 port. Scan for codes, and look for C0598 among the retrieved codes. Review the freeze frame data to understand the conditions under which the code was triggered, and check for any accompanying codes that may help diagnose the issue.

What vehicles are most commonly affected by C0598?

C0598 is frequently reported in models like the 2014-2020 Chevrolet Malibu, 2015-2018 Buick Regal, and some 2016-2019 GMC vehicles. Always check for any recalls or technical service bulletins related to the steering system in your specific vehicle model.

How can I prevent C0598 from happening again?

To prevent future occurrences of C0598, ensure regular maintenance of your vehicle's steering system, including periodic inspections and recalibrations after repairs. Additionally, keep the steering mechanism clean and free from debris.

What is C0598?

The Diagnostic Trouble Code (DTC) C0598 indicates a malfunction related to the steering angle sensor. This component plays a critical role in modern vehicles, especially those equipped with advanced driver-assistance systems (ADAS) and electronic stability control. The steering angle sensor measures the angle of the steering wheel and sends this information to the vehicle's control modules. When the C0598 code is triggered, it generally means that the steering angle sensor's signal is either incorrect or not being received properly by the vehicle's computer. For car owners, this can lead to issues such as the loss of power steering assist, erratic steering behavior, and even the activation of the vehicle's traction control system when not needed. Ignoring this code can lead to further complications, such as increased wear on your vehicle’s tires and suspension system, as well as a decrease in overall safety due to impaired handling. If you own a Chevrolet Malibu from 2014 to 2020, or similar models from other manufacturers that utilize a similar system, it's essential to address this code promptly to maintain optimal driving performance and safety.

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

Symptoms

Common symptoms when C0598 is present:

  • The check engine light illuminates, indicating potential issues with the vehicle’s steering system.
  • Steering feels unusually stiff or loose, making it difficult to maintain control while driving.
  • The traction control or stability control warning lights may activate unexpectedly, leading to confusion during normal driving conditions.
  • Unusual noises may be heard from the steering column, such as grinding or clicking, which could indicate a failing sensor.
  • The steering wheel may not return to the center position after a turn, causing erratic vehicle behavior in corners.

Possible Causes

Most common causes of C0598 (ordered by frequency):

  1. The most common cause of C0598 is a faulty steering angle sensor, which has a likelihood of around 70%. This can occur due to wear and tear over time.
  2. A second common cause could be wiring issues such as frayed or damaged wires, which might disrupt the sensor's signal to the vehicle's computer.
  3. A third cause can be related to improper calibration after repairs or replacements. Regular maintenance checks and recalibrations can help avoid this issue.
  4. Less common but serious causes include failing Electronic Control Units (ECUs) that manage the steering system, which may require replacement.
  5. A rare cause could involve software glitches in the vehicle’s onboard systems, necessitating a software update to resolve the issue.
