Can I drive my car with B14D2 or should I stop immediately?
While you can technically drive the vehicle, it's not advisable to ignore the B14D2 code as it directly impacts parking safety. It's best to address the issue as soon as possible to avoid potential accidents.
How can I diagnose B14D2 myself using GeekOBD APP?
Using the GeekOBD APP, you can scan for error codes and view freeze frame data that shows the vehicle's condition at the time the error occurred. This insight helps you identify potential issues with the BCM or the parking sensors.
What vehicles are most commonly affected by B14D2?
The B14D2 code is frequently seen in models like the 2016-2020 Ford Explorer and other vehicles equipped with similar parking assist technology. It's advisable to check for any recalls related to the BCM for your specific make and model.
How can I prevent B14D2 from happening again?
Regular maintenance checks, including inspections of electrical systems and wiring, can help prevent B14D2 from recurring. Ensure your vehicle’s BCM software is updated according to manufacturer specifications.
What is B14D2?
The DTC B14D2 is a diagnostic trouble code that indicates a problem with the vehicle's body control module (BCM), specifically related to the parking assist system. This code often surfaces in vehicles such as the 2016-2020 Ford Explorer, where it can affect the operation of various systems including the rear parking sensors and related safety features. When this code is triggered, it usually means that the BCM is unable to communicate properly with the sensors or that a malfunction has been detected within the system. This can lead to issues such as the parking assist feature not functioning correctly, which can compromise the driver's ability to park safely. In real-world terms, if you're experiencing this code, you might notice that your parking sensors are either not beeping at all or are providing false alerts. Ignoring this code can lead to more significant safety issues, particularly when reversing or parking, so addressing it promptly is essential for your safety and the safety of others on the road.
System: B - Body (Airbags, Lighting, Security, Climate Control)
Symptoms
Common symptoms when B14D2 is present:
- The parking assist system fails to activate, leaving you without warnings when close to obstacles.
- Warning lights on the dashboard, such as the parking sensor indicator, remain illuminated.
- Intermittent beeping from the parking sensors even when no obstacles are present, causing confusion.
- The vehicle may experience electrical issues, such as malfunctioning lights or locks, linked to the BCM.
- In some cases, the vehicle’s backup camera may not display an image when the vehicle is in reverse.
Possible Causes
Most common causes of B14D2 (ordered by frequency):
- 1. Faulty body control module (BCM) - This is the most common cause, accounting for around 60% of cases. A malfunctioning BCM can lead to communication issues with sensors.
- 2. Damaged wiring or connectors - Corroded or frayed wiring can disrupt signals between the BCM and the parking sensors, leading to a 25% likelihood of this issue.
- 3. Sensor malfunction - The parking sensors themselves may fail, either due to physical damage or electronic failure, which accounts for about 10% of cases.
- 4. Software issues - Occasionally, software glitches can cause the BCM to misread sensor data, although this is less common.
- 5. Environmental factors - Water intrusion or extreme temperatures can affect BCM performance, posing a rare but serious risk.

Diagnostic Steps
Professional B14D2 Diagnosis Process
Follow these systematic steps to accurately diagnose B14D2. Each step builds on the previous one to ensure accurate diagnosis.
Step 1: Initial visual inspection - Check for obvious signs like damaged wiring, loose connections, or corrosion, which should take about 5-10 minutes
Step 2: OBD2 scan with GeekOBD APP - Use this app to retrieve all codes and freeze frame data, giving you context about the fault; this will take approximately 10-15 minutes
Step 3: Component testing - Test the BCM and parking sensors using a multimeter or a specialized diagnostic tool to confirm functionality, which may take 20-30 minutes
Step 4: System function test - After any repairs, verify the operation of the parking assist system and clear codes, requiring around 10-15 minutes
Step 5: Road test verification - Drive the vehicle under various conditions to ensure the issue has been resolved, taking about 15-20 minutes
Important Notes
- Always verify the repair with GeekOBD APP after completing diagnostic steps
- Clear codes and test drive to ensure the problem is resolved
- Address underlying causes to prevent code recurrence
