What vehicles are most commonly affected by C07CE?

C07CE is commonly found in 2015-2018 Chevrolet Silverado and GMC Sierra models. If you own one of these vehicles, it's essential to be aware of this code, as it could indicate serious issues with the parking brake system.

How can I prevent C07CE from happening again?

To prevent C07CE from recurring, ensure regular maintenance of your vehicle’s electrical systems, including checking and replacing corroded wiring. Keep your vehicle's software updated and consider having periodic checks on the BCM and EPB systems during routine servicing.

What is C07CE?

The diagnostic trouble code (DTC) C07CE indicates a communication issue within the vehicle's control modules, particularly related to the body control module (BCM) and the electronic parking brake (EPB) system. This code is most commonly encountered in 2015-2018 Chevrolet Silverado and GMC Sierra models, where the vehicle may experience irregularities in the parking brake functionality. The BCM is responsible for various functions, including controlling lights, locks, and the parking brake system. When there’s a fault in communication, it can lead to significant operational issues. Drivers may notice that the electronic parking brake does not engage or disengage correctly, leading to potential safety hazards. Ignoring this code can result in further complications, such as complete failure of the parking brake system or other related components, which may affect the vehicle's overall safety and reliability. It's crucial for car owners to address this code promptly to avoid more severe issues down the line.

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

Symptoms

Common symptoms when C07CE is present:

  • The check engine light remains illuminated, indicating a persistent issue that needs diagnosis.
  • The electronic parking brake fails to engage or disengage properly, leading to concerns about securing the vehicle when parked.
  • Drivers may experience a decrease in vehicle functionality, such as problems with lights or locks, due to the BCM malfunction.
  • Unexpected warning messages may appear on the dashboard, indicating system failures or malfunctions.
  • Strange noises or grinding sounds may occur when attempting to engage the parking brake, suggesting mechanical issues.

Possible Causes

Most common causes of C07CE (ordered by frequency):

  1. 1. Faulty body control module (BCM) - This is the most common cause, accounting for approximately 60% of cases. The BCM may fail due to electrical issues, water damage, or manufacturing defects.
  2. 2. Wiring issues - Damaged or corroded wiring connections can disrupt communication between the BCM and the EPB system, making up about 25% of cases. Inspecting wiring for wear and tear can prevent future problems.
  3. 3. Software glitches - Occasionally, the BCM may require a software update to resolve bugs causing communication failure, representing about 10% of issues. Regular software updates can help mitigate this.
  4. 4. Malfunctioning electronic parking brake components - Rarely, individual components of the EPB may fail, leading to communication issues and representing about 4% of cases.
  5. 5. Electrical interference - In some instances, other electronic systems in the vehicle may interfere with the BCM's signals, though this is less common.
