What is C0605?

The DTC C0605 code indicates a malfunction related to the Steering Control Module (SCM) in your vehicle. This code is primarily triggered when the vehicle's onboard diagnostic system detects a problem with the communication or performance of the steering control module. The SCM plays a crucial role in managing power steering assist, ensuring that the steering feel is smooth and responsive. A malfunction can lead to increased steering effort, which might create safety concerns, especially during low-speed maneuvers or tight turns. Commonly found in vehicles like the 2014-2019 Chevrolet Silverado and 2013-2017 Ford Fusion, this code can have various implications. Drivers may experience symptoms such as a warning light on the dashboard, difficulty steering, or an erratic steering feel. If left unresolved, it could potentially lead to further complications, such as complete steering failure. It's essential to address this issue promptly to maintain vehicle control and safety.

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

Symptoms

Common symptoms when C0605 is present:

  • The check engine light or steering warning light illuminates on the dashboard, indicating a potential issue with the steering system.
  • Steering feels heavy or unresponsive, particularly at low speeds, making it difficult to maneuver the vehicle.
  • Increased steering effort required, leading to driver fatigue, especially during long drives or in heavy traffic.
  • Unusual noises, such as grinding or clicking, may be heard when turning the steering wheel, suggesting mechanical issues in the system.
  • Intermittent steering assist failures, where the steering feels normal at times and then becomes unresponsive.

Possible Causes

Most common causes of C0605 (ordered by frequency):

  1. The most common cause of the C0605 code is a faulty steering control module, accounting for approximately 70% of cases. This can occur from electrical issues, such as corroded connectors or damaged wiring.
  2. Another possible cause is software issues within the steering control module, which may require a reprogramming or software update to resolve.
  3. Electrical problems, including blown fuses or poor ground connections, can also trigger this code. Regularly checking the vehicle's electrical system can help prevent these issues.
  4. Less commonly, mechanical failures within the steering system, such as a damaged rack and pinion, can cause the SCM to malfunction.
  5. In rare cases, a malfunctioning vehicle speed sensor may falsely signal the SCM, leading to the setting of the C0605 code.
