What vehicles are most commonly affected by C0B2C?

The C0B2C code is frequently seen in Ford vehicles, particularly models like the 2016-2021 Ford Explorer and Ford Fusion. It's important to check for any recalls or service bulletins related to the EPB system for your specific model.

How can I prevent C0B2C from happening again?

Regular maintenance of your vehicle's braking system, ensuring proper battery health, and keeping an eye on any warning lights can help prevent the recurrence of the C0B2C code.

What is C0B2C?

The diagnostic trouble code (DTC) C0B2C is related to the vehicle's powertrain control module (PCM) and typically indicates a fault in the electric parking brake (EPB) system. This code is commonly found in 2016-2021 Ford models, including the Ford Explorer and Ford Fusion. When the C0B2C code is triggered, it signifies that the PCM has detected a malfunction in the EPB module or its associated circuits. The electric parking brake is an important safety feature that allows the driver to engage and disengage the brake electronically, often with a simple press of a button. If this system fails, it can lead to the inability to secure the vehicle when parked, posing a safety risk. Additionally, the vehicle may enter a limp mode, limiting performance to prevent damage. Owners may notice that the parking brake warning light remains illuminated on the dashboard. Ignoring this issue could lead to more severe problems, including total failure of the parking brake system, which could result in costly repairs. Therefore, addressing the C0B2C code promptly is essential for maintaining vehicle safety and functionality.

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

Symptoms

Common symptoms when C0B2C is present:

  • The parking brake warning light remains illuminated on the dashboard, indicating a fault in the system.
  • The vehicle fails to engage or disengage the parking brake, making it unsafe to park on inclines.
  • Drivers may experience a grinding noise when attempting to engage the parking brake, signaling potential mechanical issues.
  • Unexpected vehicle roll when parked, highlighting a failure in the parking brake system.
  • The vehicle enters limp mode, limiting speed and performance due to safety protocols triggered by the fault.

Possible Causes

Most common causes of C0B2C (ordered by frequency):

  1. The most common cause of the C0B2C code is a faulty electric parking brake module, with a likelihood of about 60%. This could result from wear and tear or electrical issues.
  2. Another frequent cause is damaged wiring or poor connections within the EPB circuit. Corrosion or physical damage can lead to intermittent failures.
  3. In some cases, a low battery voltage can cause the EPB system to malfunction, leading to the C0B2C code being triggered. Regular battery maintenance can help prevent this.
  4. Less common but serious causes include a malfunctioning brake switch, which can prevent the system from recognizing when the brake is applied, leading to unsafe conditions.
  5. A rare cause of the C0B2C code could be a software glitch within the PCM, necessitating an update or reprogramming of the module.
