What is B06C8?
The diagnostic trouble code (DTC) B06C8 indicates a problem with the power liftgate module, particularly focusing on a malfunction in the liftgate's motor or actuator system. This code is usually triggered when the vehicle's onboard computer detects that the liftgate motor is not performing as expected. For car owners, this means that the liftgate may not open or close properly, which can be a significant inconvenience, especially for families who rely on this feature for loading and unloading cargo. The liftgate's functionality is essential in many SUVs, including popular models like the Ford Explorer and Lincoln MKX from 2016 to 2019. If left unaddressed, a B06C8 code can lead to further complications in the vehicle's electrical system, potentially affecting other components and systems. This code is often accompanied by symptoms such as an inoperative liftgate, warning lights on the dashboard, or unusual noises when attempting to operate the liftgate. It is crucial to address this code promptly to avoid more extensive repairs in the future.
System: B - Body (Airbags, Lighting, Security, Climate Control)
Symptoms
Common symptoms when B06C8 is present:
- The liftgate does not open or close, which can be frustrating when trying to load groceries or luggage.
- Dashboard warning lights, particularly the liftgate or electrical system warning, may illuminate, indicating a problem.
- Strange noises when operating the liftgate, such as grinding or clicking, may suggest mechanical failure.
- Frequent issues with the liftgate's automatic functions, including delayed responses or failure to respond at all.
- Inconsistencies in the liftgate's operation, such as opening partially or closing unexpectedly, which can be a safety hazard.
Possible Causes
Most common causes of B06C8 (ordered by frequency):
- The most common cause is a faulty liftgate motor, accounting for about 60% of B06C8 cases. This can result from wear and tear or exposure to moisture.
- Another prevalent cause is a malfunctioning liftgate actuator, which typically happens due to electrical failures or damaged wiring.
- Poor electrical connections or corroded terminals can also trigger the B06C8 code, so regular maintenance and inspections can help prevent this.
- Less common but serious issues include a malfunctioning Body Control Module (BCM), which can affect several electrical systems in the vehicle.
- A rare cause is software glitches in the vehicle's control module, which may require a firmware update from the dealer.
