To diagnose C0C08 using the GeekOBD APP, first connect your OBD2 scanner to the vehicle's port. Use the app to retrieve all diagnostic trouble codes and review freeze frame data for context on when the issue occurred. Follow up with component testing based on the codes retrieved.

What vehicles are most commonly affected by C0C08?

C0C08 frequently affects vehicles like the 2016-2020 Ford Explorer and 2017-2021 Jeep Grand Cherokee. Owners of these models should be particularly vigilant for this code and related electrical issues.

How can I prevent C0C08 from happening again?

Regular vehicle maintenance is key to preventing C0C08. Ensure that your vehicle's electrical system is inspected periodically, keep connections clean and free from corrosion, and have software updates performed as recommended by the manufacturer.

What is C0C08?

DTC C0C08 is a diagnostic trouble code that signifies a problem within the vehicle's network communication system, specifically related to the body control module (BCM) and the communication with other modules. This code often appears when there's an interruption or failure in communication between the BCM and other systems, which can lead to various electrical issues in the vehicle. For instance, you might experience unresponsive power windows, malfunctioning lighting systems, or issues with the dashboard indicators. The BCM plays a central role in managing various electrical functions, and when it fails to communicate effectively, it can cause a cascade of problems. Ignoring this code can lead to more significant electrical failures, potentially leaving you stranded or causing safety concerns while driving. If you own a vehicle like the 2016-2020 Ford Explorer or the 2017-2021 Jeep Grand Cherokee and see this code, it’s essential to address it promptly to ensure your vehicle operates safely and efficiently.

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

Symptoms

Common symptoms when C0C08 is present:

  • The check engine light remains illuminated continuously, which can be concerning for drivers.
  • The power windows may operate inconsistently, sometimes failing to respond to commands.
  • Dashboard lights may flicker or not illuminate at all, making it difficult to monitor vehicle conditions.
  • You might experience issues with the vehicle's lighting systems, such as headlights not functioning properly.
  • Unexpected electrical failures in other systems, leading to decreased overall vehicle functionality.

Possible Causes

Most common causes of C0C08 (ordered by frequency):

  1. The most common cause of C0C08 is a faulty body control module (BCM), which occurs in approximately 60% of cases. This can happen due to wear and tear over time or exposure to water damage.
  2. Another likely cause is damaged wiring or poor connections within the BCM circuit. Corrosion or frayed wires could lead to a break in communication, occurring in about 25% of cases.
  3. A less common cause is software issues within the BCM itself, which can sometimes be resolved through a software update or reset. Preventive maintenance by regularly checking for software updates can help avoid this.
  4. In rare cases, issues with other modules in the vehicle that interact with the BCM might cause this code. This scenario is serious, as it could require extensive diagnostics to identify.
  5. A very rare cause could be a manufacturing defect in the BCM. If your vehicle is still under warranty, this might be covered.
