What is C07B7?

The DTC C07B7 signifies a problem related to the electric parking brake system, commonly found in various Ford and Lincoln models, particularly from 2015 to 2020. This code indicates that the Electric Parking Brake (EPB) module has detected a fault in the system. When the parking brake is activated, the EPB uses an electric motor to engage the brake mechanism, and any issues in this system can prevent the parking brake from functioning correctly. Drivers may experience symptoms such as the inability to release the parking brake, unexpected brake engagement, or warning lights illuminating on the dashboard. Ignoring this code can lead to safety issues, as a malfunctioning parking brake could lead to vehicle rollaway when parked. Furthermore, if the issue persists, it could lead to increased wear on the brake components, necessitating costly repairs or replacements. Car owners should be aware that the resolution of this issue often requires professional diagnostics and possibly the replacement of the EPB module or associated wiring.

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

Symptoms

Common symptoms when C07B7 is present:

  • The parking brake warning light illuminates on the dashboard, indicating a potential issue with the system.
  • The vehicle may not shift out of park, as the parking brake fails to release properly.
  • Drivers may notice a grinding noise coming from the rear brakes when the electric parking brake is engaged, suggesting mechanical issues.
  • Unexpected engagement of the parking brake while driving, which can lead to a sudden loss of speed and control.
  • Reduced braking efficiency as the vehicle struggles to stop when the parking brake is activated due to malfunction.

Possible Causes

Most common causes of C07B7 (ordered by frequency):

  1. The most common cause of the C07B7 code is a faulty Electric Parking Brake (EPB) module, which is responsible for controlling the parking brake system, with a likelihood of around 60%. This can result from electrical faults or internal module failures.
  2. Another potential cause is damaged wiring or connectors within the EPB system, which can lead to loss of signals or short circuits, accounting for about 25% of cases.
  3. Worn or damaged brake components, such as the calipers or pads, can also trigger this code, especially in older vehicles or those with high mileage. Regular inspections can help prevent this issue.
  4. Less commonly, software glitches or updates in the vehicle's control module may lead to false readings, requiring a software update or reset.
  5. In rare instances, environmental factors such as water intrusion into the EPB module can cause failures, necessitating thorough inspections of the module location.
