What is C0AE7?
The DTC code C0AE7 typically indicates a fault related to the vehicle's communication network, particularly concerning the Body Control Module (BCM) or related sensors. In simpler terms, it suggests that there is a disruption in the electronic signals that allow various parts of your vehicle to communicate effectively. This code is often found in vehicles like the 2016-2020 Ford Explorer, among others. When this code appears, you may experience several symptoms, including warning lights on your dashboard, malfunctioning electronic accessories, or issues with the vehicle’s locking system. While it may not immediately jeopardize your safety, ignoring this code can lead to more significant electrical issues over time. If not addressed, the underlying problems can escalate, potentially resulting in costly repairs. It’s essential to approach this issue promptly to maintain your vehicle's overall functionality and safety. Regularly scanning for diagnostic trouble codes using tools like the GeekOBD APP can help catch these issues early and prevent further complications.

Symptoms
Common symptoms when C0AE7 is present:
- Check engine light may illuminate and remain on, indicating an issue with the vehicle's electrical system.
- Electronic accessories, such as windows or locks, may malfunction or respond inconsistently, making the driving experience frustrating.
- Fuel economy may decrease unexpectedly, as the vehicle may not operate efficiently due to electrical communication failures.
- Dashboard warning lights related to the vehicle's body control systems may activate, alerting the driver to potential problems.
- In some cases, the vehicle might experience intermittent starting issues, leading to frustration for the driver.
Possible Causes
Most common causes of C0AE7 (ordered by frequency):
- The most common cause of C0AE7 is a faulty Body Control Module (BCM), which may account for about 40% of cases. This could be due to water damage, electrical shorts, or age-related wear.
- Another prevalent cause is damaged wiring or corroded connectors in the vehicle's network, which can lead to poor communication and signal loss between components.
- A third potential cause is a weak battery or poor connections that may lead to voltage issues within the system. Regular battery maintenance can help prevent this problem.
- Less common causes include software issues within the BCM that may require a reprogramming to fix, which is more prevalent in newer models.
- Lastly, while rare, an aftermarket modification or accessory installed incorrectly can lead to C0AE7, disrupting the vehicle’s electronic communication.
