What is C049E?

The diagnostic trouble code (DTC) C049E indicates an issue with the steering system, specifically concerning the steering assist. This code is often found in vehicles like the 2016-2019 Chevrolet Malibu and is part of the vehicle’s electronic power steering (EPS) system. When the C049E code is triggered, it generally signifies that the steering control module has detected a fault in the steering assist circuit. This can lead to a range of issues, from the steering feeling too heavy to a complete loss of steering assistance, which can be dangerous while driving. The implications of this code can vary from simple electrical issues, such as a bad connection or faulty wiring, to more complex problems like a failing power steering motor. It’s crucial to address this code promptly as ignoring it could result in further damage to the steering system, increased repair costs, and safety risks while operating the vehicle.

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

Symptoms

Common symptoms when C049E is present:

  • The check engine light illuminates or flashes, indicating a problem with the steering system.
  • Steering feels unusually heavy or difficult to turn, especially at low speeds.
  • Intermittent loss of power steering assistance, leading to erratic steering behavior.
  • Unusual noises occur when steering, such as grinding or whining, indicating potential mechanical issues.
  • Dashboard warning lights related to vehicle stability or traction control may also appear.

Possible Causes

Most common causes of C049E (ordered by frequency):

  1. The most common cause of the C049E code is a faulty steering assist motor, which occurs in approximately 40% of cases. This motor may fail due to wear and tear or electrical issues.
  2. A second common cause is damaged wiring or connectors within the steering system, accounting for about 30% of cases. Corrosion or frayed wires can disrupt the electrical flow.
  3. Another possible cause is a malfunctioning steering control module, which may not properly communicate with the steering motor. This can happen if the module is exposed to extreme conditions or if it fails internally.
  4. Less common but serious causes include a complete failure of the EPS system, which may require significant repairs or replacement.
  5. A rare cause involves software issues within the vehicle’s onboard computer that may require a software update or reprogramming.
