What is B0682?
The B0682 diagnostic trouble code (DTC) is specific to issues within the vehicle's body control module (BCM) and is particularly relevant for owners of 2015-2018 Jeep Grand Cherokees. This code indicates a malfunction related to the driver’s door module, which controls various functions such as power windows, locks, and mirrors. When B0682 is triggered, it usually means there is a communication problem between the BCM and the door module. In practical terms, this can lead to several inconveniences; for example, you might find that your power windows do not operate correctly, your door locks may fail to engage, or the vehicle’s interior lighting may malfunction. Ignoring this code can lead to further electrical issues and may compromise vehicle security, as the door locks may not function reliably. Therefore, timely diagnosis and repair are crucial. Not only can this enhance your driving experience, but it also ensures your vehicle remains safe and efficient.
System: B - Body (Airbags, Lighting, Security, Climate Control)
Symptoms
Common symptoms when B0682 is present:
- The check engine light or warning light related to the door module stays illuminated, indicating a persistent issue.
- Power windows fail to operate properly, either getting stuck or not responding when using the controls.
- The locks do not function correctly, which may leave your vehicle vulnerable to theft if the door locks fail.
- Interior lights may flicker or not turn on when the doors are opened, affecting visibility inside the vehicle.
- Malfunctioning mirrors, where the power adjustment feature does not respond, leading to poor visibility.
Possible Causes
Most common causes of B0682 (ordered by frequency):
- The most common cause of B0682 is a faulty driver's door module, with a likelihood of about 60%. This can happen due to wear and tear or exposure to moisture.
- Another frequent cause is damaged wiring or connectors in the door harness, which can disrupt communication between the BCM and the door module.
- Corrosion in the connector pins can also lead to communication failures. Regular inspections can help prevent this by ensuring connections remain clean and secure.
- Less common, but serious, could be a failing body control module itself, which may require complete replacement and diagnostic testing.
- A rare cause could involve software issues within the BCM, potentially resolvable through an update from the manufacturer.
