What is B0680?

The diagnostic trouble code (DTC) B0680 indicates an issue with the driver’s door lock actuator or its related circuit. This code is commonly found in various Honda and Acura models, particularly those manufactured between 2010 and 2020. When the B0680 code triggers, it typically signifies that the vehicle's onboard computer has detected a malfunction in the system responsible for locking and unlocking the driver's door. This could lead to complications such as the inability to lock or unlock the driver's door remotely or manually, which can be both a security concern and a convenience issue. Additionally, this malfunction might affect other systems in the vehicle, such as the power windows and mirrors, as they may share the same electrical circuit. In practical terms, if you encounter the B0680 code, it’s crucial to address the issue promptly. Ignoring this code could lead to further electrical problems or even the failure of other components connected to the door locking mechanism. Addressing this code early can save you money on more extensive repairs down the line and ensure your vehicle operates safely and efficiently.

Symptoms

Common symptoms when B0680 is present:

  • The check engine light stays on constantly, indicating an ongoing problem with the door locking system.
  • You may experience difficulty locking or unlocking the driver's door, either manually or via the remote key fob.
  • Power windows may become unresponsive or function erratically, as they could be linked to the same electrical circuit.
  • Flickering lights in the driver's side door panel might occur, suggesting electrical issues.
  • You might hear unusual sounds when attempting to lock or unlock the door, indicating a malfunctioning actuator.

Possible Causes

Most common causes of B0680 (ordered by frequency):

  1. The most common cause of B0680 is a faulty door lock actuator, with about 60% of cases attributed to this issue. This component can wear out over time due to repeated use.
  2. Another common cause is damaged wiring or connectors in the door lock circuit, which can happen from wear and tear or exposure to moisture.
  3. Corrosion at connectors can lead to intermittent failures. Regularly inspecting and cleaning electrical connections can help prevent this.
  4. Less commonly, a failing body control module (BCM) may send incorrect signals to the door lock system, but this is more rare.
  5. A malfunctioning key fob can also trigger this code, particularly if the fob is not communicating effectively with the vehicle's system.
