What is C05A6?

DTC C05A6 is a diagnostic trouble code that indicates an issue related to the vehicle's steering or suspension system, particularly in models equipped with advanced driving assistance systems (ADAS). This code is often found in vehicles such as the 2016-2019 Ford Edge and 2017-2020 Chevrolet Silverado. When the C05A6 code is triggered, it typically means there is a problem with the control module responsible for monitoring the stability of the vehicle, which could lead to compromised handling and safety. Drivers might notice that their vehicle experiences unusual steering behavior, such as pulling to one side or a lack of responsiveness when turning. Ignoring this code can lead to further mechanical issues, escalating repair costs, and potentially dangerous driving conditions. To effectively address the C05A6 code, it is crucial to understand its implications for vehicle performance, as it may affect traction control, anti-lock braking systems, and overall driving comfort. It is advisable to address this code promptly to ensure the longevity of your vehicle and maintain safety on the road.

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

Symptoms

Common symptoms when C05A6 is present:

  • Check engine light illuminates or flashes, indicating a fault in the stability control system.
  • Steering feels loose or unresponsive, leading to difficulties in handling the vehicle.
  • Unusual noises from the steering or suspension system, such as clunking or grinding, which can indicate component failure.
  • Vehicle pulls to one side during driving, affecting the alignment and overall stability.
  • Inconsistent traction control operation, where the system engages or disengages unexpectedly.

Possible Causes

Most common causes of C05A6 (ordered by frequency):

  1. The most common cause is a faulty steering angle sensor, which is responsible for sending data to the vehicle's control module (estimated likelihood: 40%).
  2. A damaged or corroded wiring harness can lead to intermittent signals, resulting in the C05A6 code being triggered. This might occur due to exposure to moisture or road debris.
  3. Worn-out suspension components, such as bushings or struts, can affect the vehicle's stability and trigger this code. Regular inspections can help prevent this issue.
  4. Less common but serious causes include a malfunctioning electronic stability control (ESC) module, which can compromise vehicle safety.
  5. Rarely, a software glitch in the vehicle's computer system can trigger the C05A6 code, necessitating a software update or reprogramming.
