What is C0AEB?

DTC C0AEB is a diagnostic trouble code indicating a problem with the vehicle's seat belt system, specifically referring to an issue with the seat belt retractor. This code is most commonly seen in vehicles like the 2014-2019 Ford F-150 and the 2015-2020 Chevrolet Silverado. The seat belt retractor is responsible for retracting the seat belt after it has been extended. When this code appears, it usually means the seat belt retractor is malfunctioning or has detected a fault in its operation. The implications of this code can be serious, as a faulty seat belt retractor can compromise the effectiveness of the seat belt during a crash, potentially leading to severe injury. Drivers may notice the seat belt warning light illuminated on their dashboard, which serves as a reminder that the seat belt system requires attention. Ignoring this code might not only endanger occupants but could also lead to failed inspections or complications during insurance claims. Addressing the issue promptly is crucial for ensuring the safety of all passengers in the vehicle.

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

Symptoms

Common symptoms when C0AEB is present:

  • The seat belt warning light is constantly illuminated on the dashboard, indicating a fault in the seat belt system.
  • Seat belts may not retract properly, leading to slack in the belt, which can affect safety in the event of a collision.
  • Increased noise or friction when pulling out the seat belt, suggesting a mechanical issue with the retractor.
  • A noticeable delay or failure in the seat belt locking mechanism when pulled quickly, which can be alarming.
  • Possible failure of the seat belt to extend fully, leaving the driver or passengers without proper restraint.

Possible Causes

Most common causes of C0AEB (ordered by frequency):

  1. The most common cause of C0AEB is a defective seat belt retractor, which has a likelihood of about 70%. This can occur due to wear and tear or internal component failure.
  2. A secondary cause might be damaged wiring or connectors related to the seat belt system. If these connections are loose or corroded, they can lead to erratic behavior.
  3. Faulty sensors within the seat belt assembly can also trigger this code. Regular inspections can help prevent these issues.
  4. Less frequently, the problem could be a malfunctioning Body Control Module (BCM), which manages the seat belt system's operations.
  5. In rare cases, the issue might arise from a collision that has compromised the seat belt system, leading to a need for extensive repairs.
