Common Questions

What does B06C2 mean and how does it affect my car?

The B06C2 code indicates a malfunction in the rear liftgate lock actuator, which can lead to difficulties in locking or unlocking your vehicle's rear hatch. This not only affects convenience but can also pose a security risk if the liftgate fails to secure properly.

What are the most common causes of B06C2 and how much does it cost to fix?

The most common cause is a faulty rear liftgate lock actuator, which typically costs between $150 and $300 to replace. Damaged wiring or a malfunctioning BCM can also cause the issue, with reprogramming costs around $100 to $200.

Can I drive my car with B06C2 or should I stop immediately?

While you can technically drive your vehicle with the B06C2 code, it's not advisable to do so for long periods. Ignoring the code may lead to further complications, including an inability to secure your liftgate properly.

How can I diagnose B06C2 myself using GeekOBD APP?

To diagnose B06C2, download the GeekOBD APP and connect it to your vehicle's OBD2 port. Use the app to scan for trouble codes and review the freeze frame data to get insights into when the issue occurred.

What vehicles are most commonly affected by B06C2?

The B06C2 code is often found in 2015-2020 Ford Explorers and other Ford models with similar BCM configurations. It’s essential to check for any recalls or technical service bulletins (TSBs) related to this issue.

How can I prevent B06C2 from happening again?

To prevent the B06C2 code from reappearing, regularly inspect the wiring and connectors in the liftgate area for corrosion or damage. Ensure that the vehicle is washed frequently to prevent salt and moisture build-up, especially in winter months.

What is B06C2?

The diagnostic trouble code (DTC) B06C2 refers to a fault detected in the vehicle's body control module (BCM) specifically related to the rear liftgate or hatch lock actuator. This code typically indicates that the BCM has received a signal or input that is outside the expected range, suggesting a malfunction in the liftgate locking mechanism. In practical terms, if your vehicle has triggered this code, you may experience issues with the rear hatch not locking or unlocking properly, which can lead to security concerns and potential inconvenience. For many Ford Explorer owners from 2015-2020, this issue can manifest as a failure to lock the liftgate, an audible chime indicating a problem, or even a warning light on the dashboard. Ignoring this code can lead to further complications, such as the liftgate being unable to open or close entirely, which could hinder access to your cargo area. The BCM oversees a network of components, so addressing the B06C2 code promptly is crucial to maintaining the overall functionality and safety of your vehicle. Addressing this issue can often involve checking the wiring and connectors associated with the liftgate, testing the actuator, or in some cases, reprogramming the BCM itself, which is a critical step for restoring proper vehicle operation.

System: B - Body (Airbags, Lighting, Security, Climate Control)

Symptoms

Common symptoms when B06C2 is present:

  • The rear liftgate does not lock or unlock, impacting the security of your vehicle.
  • An audible chime sounds when attempting to lock the vehicle, indicating a problem with the liftgate.
  • The dashboard warning light remains illuminated, alerting you to a fault in the liftgate system.
  • Difficulty in manually operating the liftgate, with resistance or complete failure to open.
  • Failure of the key fob to unlock the liftgate, causing inconvenience.

Possible Causes

Most common causes of B06C2 (ordered by frequency):

  1. The most common cause of the B06C2 code is a faulty rear liftgate lock actuator, with a likelihood of about 60%. This can occur due to wear and tear or exposure to moisture.
  2. Another frequent issue is damaged wiring or corroded connectors in the liftgate circuit, producing a 25% chance of being the culprit. Regular inspections can prevent this.
  3. Improperly programmed or malfunctioning body control module may also lead to this code appearing, though it's less common at around 10%. A professional reprogramming can often resolve this.
  4. A less frequent but serious cause could be a short circuit within the BCM itself, which can lead to further electronic issues.
  5. In rare instances, water intrusion in the BCM can cause the B06C2 code to appear, although this is not typically a common problem.
