What is B0BB3?

The B0BB3 diagnostic trouble code (DTC) indicates a problem with the vehicle's rear control module, specifically relating to the rear liftgate or trunk. This may arise in various models, particularly from 2016 to 2020 Ford Explorers, where drivers might notice issues like the rear liftgate failing to open or close properly. The rear control module is responsible for managing signals between the liftgate and the vehicle's onboard systems. When the control module detects an abnormality, it triggers the B0BB3 code, alerting the driver of a fault. Ignoring this code could lead to more severe issues, including complete liftgate failure, which could impede access to the trunk area, especially problematic for families or when transporting cargo. Additionally, the rear camera functionality could become compromised, leading to decreased safety while reversing. Addressing the B0BB3 code promptly can help restore liftgate functionality and ensure that any related systems, such as security features and rear sensors, are operating correctly.

Symptoms

Common symptoms when B0BB3 is present:

  • The check engine light or a specific warning light for the liftgate may illuminate on the dashboard, indicating a malfunction.
  • The rear liftgate may fail to open or close properly, leaving you unable to access the trunk, which can be frustrating during loading or unloading tasks.
  • You might notice that the rearview camera is not functioning as expected, impacting safety when reversing your vehicle.
  • There could be inconsistent behavior of the liftgate, such as it intermittently opening or closing on its own, which can pose a safety risk.
  • In some cases, you may hear unusual noises coming from the rear area when attempting to operate the liftgate, suggesting mechanical issues.

Possible Causes

Most common causes of B0BB3 (ordered by frequency):

  1. The most common cause of the B0BB3 code is a faulty rear control module, accounting for about 60% of cases. This module may fail due to electrical issues or water ingress.
  2. Another reason could be damaged wiring or connectors associated with the rear liftgate system, which can lead to erratic behavior or complete failure.
  3. Corrosion at the electrical connectors can also lead to this code, especially in vehicles exposed to harsh weather conditions or road salt.
  4. Less common but serious causes include a malfunctioning liftgate motor, which may require replacement to restore proper function.
  5. A rare but possible cause is software issues within the vehicle's computer systems that may require a firmware update to resolve.
