What is B028E?

The Diagnostic Trouble Code (DTC) B028E refers to a fault detected within the vehicle’s electric parking brake system. This code indicates that the Control Module has identified a malfunction concerning the parking brake actuator or its associated components. When this code is triggered, it generally implies that the parking brake may not engage or disengage properly, which could pose safety risks while driving or parking. The implications of a B028E code can vary from a simple software glitch to more serious mechanical failures. For example, if you own a 2015-2018 Ford Explorer, you may notice that the parking brake light remains illuminated, indicating a potential issue with the system. This could lead to the parking brake not holding the vehicle securely, risking rollaway accidents. Additionally, other symptoms may include inconsistent braking performance and unusual noises when engaging or disengaging the parking brake. Ignoring this code can lead to further complications and potentially expensive repairs, as the parking brake is a critical component for vehicle safety. Therefore, it is crucial to address the B028E code as soon as it appears on your dashboard.

System: B - Body (Airbags, Lighting, Security, Climate Control)

Symptoms

Common symptoms when B028E is present:

  • The parking brake warning light remains illuminated, indicating a malfunction in the electric parking brake.
  • The vehicle may roll when parked if the parking brake fails to engage properly, which can be dangerous.
  • Unusual noises, such as grinding or clicking sounds, may occur when trying to engage or disengage the parking brake.
  • You may experience a delay or failure when trying to engage the parking brake, leading to concerns about its reliability.
  • Inconsistent braking performance may be felt while driving, particularly when attempting to use the parking brake.

Possible Causes

Most common causes of B028E (ordered by frequency):

  1. The most common cause of the B028E code is a malfunctioning parking brake actuator, which has a likelihood of approximately 60%. This can occur due to wear and tear or electrical issues.
  2. A software glitch in the vehicle's control module may also trigger the B028E code, representing about 25% of cases. Updating the software can often resolve this issue.
  3. Electrical issues such as corroded connectors or damaged wiring can contribute to the problem, making it crucial to inspect these areas (around 10% likelihood).
  4. Less common causes may include a failed brake control module, which can be costly to replace and has a 4% chance of occurring.
  5. A rare cause could be a mechanical failure within the parking brake system itself, such as a broken cable, which has about a 1% likelihood.
