What is C0BB6?

DTC C0BB6 is a diagnostic trouble code indicating a problem with the vehicle's restraint control module (RCM). This module is responsible for managing the airbag system and ensuring that safety features function correctly in the event of a collision. When C0BB6 is triggered, it typically means the RCM has detected a fault in the system, which could range from a simple wiring issue to a more severe malfunction in the module itself. For car owners, this code can manifest in several ways, including the illumination of the airbag warning light on the dashboard. Ignoring this code can lead to critical safety risks, as the airbag system may not deploy correctly in an accident. It's essential to address this issue promptly to ensure the safety of all vehicle occupants. Vehicles like the 2016-2020 Ford Explorer and Fusion are among those frequently affected by this code, and addressing it early can save owners from more extensive repairs down the line.

Symptoms

Common symptoms when C0BB6 is present:

  • The airbag warning light stays on constantly, indicating a malfunction in the airbag system.
  • The vehicle may exhibit erratic behavior in other safety features, such as the seat belt reminder not functioning correctly.
  • In rare cases, the engine may experience hesitations or irregularities due to electrical interference from the RCM.
  • The dashboard might show other warning lights indicating a broader issue with the vehicle's electronic systems.
  • Owners may notice that the vehicle's safety systems, including traction control, are not responding as they should.

Possible Causes

Most common causes of C0BB6 (ordered by frequency):

  1. The most common cause of C0BB6 is a faulty restraint control module, with a likelihood of about 60%. This can happen due to age, exposure to moisture, or electrical issues.
  2. A second common cause is damaged wiring or connectors related to the airbag system, typically accounting for around 25% of cases. This can be caused by wear and tear or physical damage from accidents.
  3. Another cause can be a temporary glitch due to low battery voltage, particularly in older vehicles. Regular battery maintenance can help prevent this.
  4. Less commonly, a software issue within the RCM may lead to false codes, necessitating a software update or recalibration.
  5. A rare but serious cause could be an unreported airbag deployment that affects the module's performance, often requiring complete module replacement.
