What vehicles are most commonly affected by B03ED?
The B03ED code is frequently found in the 2015-2018 Ford F-150, as well as other Ford models that utilize similar body control systems. Always check for any recalls or Technical Service Bulletins (TSBs) related to your vehicle.
How can I prevent B03ED from happening again?
Regularly inspect the wiring and connectors associated with the liftgate, ensure proper maintenance of the vehicle's electrical systems, and consider periodic software updates for the BCM if available.
What is B03ED?
The diagnostic trouble code (DTC) B03ED is associated with the body control module (BCM) and indicates a fault in the vehicle's communication system, typically related to the power liftgate or tailgate. This code can arise due to wiring issues, faulty sensors, or a malfunctioning BCM. When this code is triggered, it can cause various components associated with the liftgate system to malfunction, leading to operational issues such as the liftgate not opening or closing properly. If ignored, this can lead to further complications or potential failures in related systems, causing inconvenience and safety concerns. For many car owners, especially those who rely on the liftgate for daily tasks, addressing this issue promptly is essential to ensure smooth vehicle operation. Vehicles like the 2015-2018 Ford F-150 are particularly prone to this issue, often due to wear and tear on the electrical components over time. Understanding the implications of this code and addressing it quickly can help prevent more significant problems down the road.
System: B - Body (Airbags, Lighting, Security, Climate Control)
Symptoms
Common symptoms when B03ED is present:
- The check engine light remains illuminated, indicating a persistent issue with the vehicle's systems.
- The liftgate does not respond when using the remote or switch, causing inconvenience when loading or unloading cargo.
- You may experience intermittent problems where the liftgate opens unexpectedly or fails to close properly, leading to safety hazards.
- You notice that other features controlled by the body control module, such as interior lights or door locks, are also malfunctioning.
- There is an unusual increase in battery drain, which can be caused by the BCM trying to communicate with faulty components.
Possible Causes
Most common causes of B03ED (ordered by frequency):
- The most common cause is a defective body control module, accounting for about 50% of cases. This can happen due to wear or manufacturing defects.
- Another frequent cause is damaged wiring or poor connections, which can lead to communication failures between the BCM and the liftgate components.
- A faulty liftgate position sensor can also trigger the B03ED code, leading to incorrect feedback to the BCM.
- Less commonly, software issues within the BCM may cause intermittent faults. This can sometimes be resolved with a software update.
- In rare cases, corrosion or moisture intrusion in electrical connectors can result in this code being set, potentially leading to more extensive repairs.

Diagnostic Steps
Professional B03ED Diagnosis Process
Follow these systematic steps to accurately diagnose B03ED. Each step builds on the previous one to ensure accurate diagnosis.
Step 1: Step 1: Perform an initial visual inspection of the wiring and connectors associated with the liftgate and BCM
Step 1: Perform an initial visual inspection of the wiring and connectors associated with the liftgate and BCM. Look for signs of damage or corrosion (5-10 minutes).
Step 2: Step 2: Use an OBD2 scanner, like the GeekOBD APP, to retrieve the B03ED code along with any additional codes that may give context to the issue (10-15 minutes)
Step 2: Use an OBD2 scanner, like the GeekOBD APP, to retrieve the B03ED code along with any additional codes that may give context to the issue (10-15 minutes).
Step 3: Step 3: Conduct component testing on the liftgate position sensor and BCM using a multimeter to verify proper operation (20-30 minutes)
Step 3: Conduct component testing on the liftgate position sensor and BCM using a multimeter to verify proper operation (20-30 minutes).
Step 4: Step 4: If repairs are made, perform a system function test to ensure everything is operating correctly and clear the codes (10-15 minutes)
Step 4: If repairs are made, perform a system function test to ensure everything is operating correctly and clear the codes (10-15 minutes).
