What is C064A?

The DTC code C064A indicates a problem with the vehicle's steering control module, particularly related to the Electronic Stability Control (ESC) system. This code is often triggered when the module detects a fault within the steering system, which can lead to serious safety issues if left unaddressed. You may notice that your vehicle's steering feels off, or the stability control light may illuminate on your dashboard. This code can affect various makes and models, but it is notably common in Chevrolet vehicles like the 2016-2019 Malibu, Impala, and Equinox. If the C064A code appears, it could mean that there is a malfunction in the steering angle sensor, the wiring harness, or even the steering control module itself. Ignoring this issue can lead to reduced vehicle control, especially in slippery conditions, as the ESC system might not function properly. Therefore, it is crucial to diagnose and address the problem promptly to ensure safe vehicle operation.

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

Symptoms

Common symptoms when C064A is present:

  • The stability control light on the dashboard stays illuminated, indicating an issue with the vehicle's stability control system.
  • Steering feels unresponsive or too loose, making it difficult to control the vehicle effectively during turns or lane changes.
  • You may experience a sudden loss of power steering assist, resulting in heavy steering, especially at low speeds.
  • The vehicle may exhibit erratic behavior when driving on slippery surfaces, such as during rain or snow.
  • Some drivers report a noticeable increase in steering resistance, making it harder to maneuver the vehicle.

Possible Causes

Most common causes of C064A (ordered by frequency):

  1. The most common cause of C064A is a malfunctioning steering angle sensor, which accounts for about 60% of cases. This sensor provides crucial data to the ESC system, and if it fails, the system can’t function properly.
  2. A damaged or corroded wiring harness connected to the steering control module can also trigger this code. This issue can often be identified through a visual inspection of the wiring.
  3. Faulty steering control modules account for around 20% of cases. These modules can become damaged due to electrical surges or moisture ingress, leading to failure in communicating with other systems.
  4. Less common causes include issues with the vehicle's battery or alternator, which can affect the operation of electronic modules if voltage levels are not stable.
  5. In rare cases, software glitches in the ESC system can also result in a C064A code. This may require a software update from the dealership or a qualified technician to resolve.
