How can I prevent B07AE from happening again?
Regular maintenance of electrical systems, checking for corrosion, and ensuring proper seals can help prevent future occurrences of the B07AE code.
What is B07AE?
The diagnostic trouble code (DTC) B07AE indicates a fault related to the Body Control Module (BCM) in vehicles, particularly noticeable in models like the 2015-2020 Ford Explorer. The BCM controls various electrical systems in your vehicle, including lighting, door locks, and security systems. When B07AE is triggered, it typically signifies that the BCM has detected an anomaly in its operation, which can lead to multiple symptoms, such as malfunctioning lights or trouble with the central locking system. In simpler terms, your car is having trouble communicating with its electrical brain, which can affect many functions. Ignoring this code can lead to more significant electrical issues or even a complete failure in systems controlled by the BCM. For everyday drivers, this could mean your car might not lock properly, the lights may not function as expected, or, in severe cases, it could prevent the vehicle from starting. It's crucial to address this code promptly to ensure your vehicle's reliability and safety.
System: B - Body (Airbags, Lighting, Security, Climate Control)
Symptoms
Common symptoms when B07AE is present:
- The check engine light remains on or intermittently blinks, signaling a potential fault within the BCM.
- Electrical components like the headlights or taillights may flicker or not operate at all, leading to safety concerns when driving at night.
- Inconsistent performance of power windows and locks, making them either unresponsive or slow to operate.
- The vehicle may exhibit difficulty starting, as the BCM also influences the ignition system and security features.
- There may be unusual behavior in the dashboard indicators, such as warning lights that illuminate unexpectedly.
Possible Causes
Most common causes of B07AE (ordered by frequency):
- The most common cause of the B07AE code is a faulty Body Control Module, which can occur in approximately 60% of reported cases. This can stem from manufacturing defects or wear and tear over time.
- Another frequent culprit is damaged wiring or connectors leading to the BCM. This can happen due to corrosion or physical damage, accounting for about 25% of issues. Always inspect the wiring harness for any visible damage.
- Moisture intrusion into the BCM can lead to short circuits, which is often preventable by ensuring proper seals and protective covers are in place, making up about 10% of cases.
- Less commonly, software issues or updates may be needed, leading to a failure in communication with other modules, although this is rare and represents about 3% of incidents.
- In rare cases, external factors such as aftermarket modifications or installations can cause interference with the BCM's operation, leading to the B07AE code.

Diagnostic Steps
Professional B07AE Diagnosis Process
Follow these systematic steps to accurately diagnose B07AE. Each step builds on the previous one to ensure accurate diagnosis.
Step 1: Step 1: Initial visual inspection - Check for obvious signs like damaged wiring, loose connections, or corrosion in the BCM area
Step 1: Initial visual inspection - Check for obvious signs like damaged wiring, loose connections, or corrosion in the BCM area. This should take about 5-10 minutes.
Step 2: Step 2: OBD2 scan with GeekOBD APP - Retrieve all codes and freeze frame data to understand the fault context
Step 2: OBD2 scan with GeekOBD APP - Retrieve all codes and freeze frame data to understand the fault context. This helps in identifying if B07AE is the only issue or if other codes are present. This step will take approximately 10-15 minutes.
Step 3: Step 3: Component testing - Use a multimeter or specific diagnostic tools to test the BCM and associated wiring
Step 3: Component testing - Use a multimeter or specific diagnostic tools to test the BCM and associated wiring. This step may take around 20-30 minutes, depending on findings.
Step 4: Step 4: System function test - After any repairs, verify the proper operation of the BCM and clear codes using the GeekOBD APP to ensure the fixes have been successful
Step 4: System function test - After any repairs, verify the proper operation of the BCM and clear codes using the GeekOBD APP to ensure the fixes have been successful. Allocate about 10-15 minutes for this.
Step 5: Step 5: Road test verification - Drive the vehicle under various conditions to confirm the repair success and that all systems are functioning as intended
Step 5: Road test verification - Drive the vehicle under various conditions to confirm the repair success and that all systems are functioning as intended. This should take around 15-20 minutes.
