What is C0E4C?
The diagnostic trouble code (DTC) C0E4C indicates a communication problem within the vehicle’s control module, specifically related to the body control module (BCM) in models like the 2016-2020 Ford Explorer. When this code is triggered, it means that the BCM is unable to properly communicate with other modules within the vehicle’s network. This could be due to a variety of issues, including faulty wiring, a malfunctioning BCM, or issues with the power supply to the module. Real-world implications include potential problems with electrical systems such as power windows, central locking, and interior lights, which may not operate correctly. In some cases, you might also notice warning lights on your dashboard, particularly the check engine light. Ignoring this DTC could lead to further electrical issues and, over time, impact the vehicle's performance and safety features. Addressing C0E4C promptly is essential to ensure that all electrical components function as intended, and to maintain the vehicle’s overall reliability.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C0E4C is present:
- Check engine light stays on constantly, indicating a persistent issue that requires attention.
- Power windows and locks may function sporadically, leading to frustration and safety concerns.
- Interior lights may flicker or not turn on, affecting visibility and convenience inside the vehicle.
- Other electrical features like the radio or climate control might exhibit erratic behavior, impacting comfort.
- In some cases, you might experience a drain on the battery if the BCM is malfunctioning, potentially leading to starting issues.
Possible Causes
Most common causes of C0E4C (ordered by frequency):
- Faulty Body Control Module (BCM) – Most common cause (around 50% likelihood). A malfunctioning BCM can disrupt communication with other modules.
- Wiring Issues – Approximately 30% of cases involve damaged wiring or corroded connectors affecting signal transmission between modules.
- Power Supply Problems – 15% of issues stem from inadequate power supply to the BCM, often due to a blown fuse or bad relay.
- Less Common: Short Circuits – Rarely, a short circuit in the wiring harness can cause communication failures between modules.
- Very Rare: Software Glitches – In some instances, outdated or corrupted software in the BCM can lead to communication errors.
