What is B0964?
DTC B0964 indicates an issue with the power liftgate control module, which is responsible for the operation of your vehicle's liftgate system. This diagnostic trouble code can arise in various vehicle makes and models, but it is notably common in the 2015-2020 Ford Explorer. Essentially, the power liftgate system facilitates the automatic opening and closing of the rear hatch, making it easier for drivers to load and unload cargo. When this code is triggered, it typically signifies that there’s a malfunction in the liftgate control module or its associated circuits. This could stem from several factors, including wiring problems, a faulty control module, or issues with the liftgate motor itself. Drivers may experience symptoms ranging from the liftgate not responding at all to erratic behavior during operation. Not addressing this issue promptly can lead to further complications, including complete failure of the liftgate system, which can severely impact the vehicle's utility, especially in everyday use. It’s crucial for vehicle owners to be aware of this code, as it not only affects convenience but could also impact safety if the liftgate were to malfunction while in motion.
