What is B0660?

DTC B0660 is a diagnostic trouble code that indicates a problem with the vehicle's power steering system, specifically relating to the Electric Power Steering (EPS) control module. This code typically signifies that the EPS control module has detected an internal fault, which can affect the steering response and overall driving experience. For vehicle owners, experiencing this code can be concerning, as it may lead to difficulty in steering, particularly at lower speeds or during sharp turns. The EPS system is designed to provide assistance based on the driver's input, so if it's not functioning correctly, it can lead to increased effort required to steer the vehicle. The implications of this code include potential safety hazards, as compromised steering can lead to accidents. It is essential to address this issue promptly to ensure the vehicle remains safe and manageable on the road. Repairing the EPS module or its associated wiring and connectors is often necessary to clear this code, and ignoring it can lead to further complications and costly repairs. Therefore, understanding the meaning and implications of DTC B0660 is crucial for maintaining the health and safety of your vehicle.

Symptoms

Common symptoms when B0660 is present:

  • The check engine light may illuminate or flash intermittently, indicating an issue.
  • Drivers might experience heavy or stiff steering, particularly noticeable when maneuvering at low speeds, making parking difficult.
  • There may be noticeable noise or grinding sounds coming from the steering column when turning, indicating potential mechanical problems.
  • Inconsistent steering feel, where the steering response varies unexpectedly, can occur, leading to a disconcerting driving experience.
  • The EPS warning light may remain lit on the dashboard, signaling that the electric power steering system is not functioning correctly.

Possible Causes

Most common causes of B0660 (ordered by frequency):

  1. The most common cause of B0660 is a faulty EPS control module, which can occur in about 60% of cases due to electrical issues or component failure.
  2. Wiring issues, such as damaged connectors or shorts in the wiring harness, can lead to a 20% likelihood of triggering this code, impacting the communication between the EPS and the vehicle's onboard computer.
  3. Another potential cause is low power steering fluid levels, which can affect the EPS system's performance; maintaining proper fluid levels is crucial to prevent this issue.
  4. A less common cause is software issues in the EPS module, which can arise from updates or glitches, affecting around 10% of reported cases.
  5. Rarely, mechanical failures of the steering column or associated components may lead to this code, but these occurrences are significantly less frequent.
