What is B0460?

DTC B0460 is a diagnostic trouble code that indicates an issue with the driver's side power window switch circuit. This code is primarily encountered in vehicles like the 2015-2018 Honda Accord. When the vehicle's onboard computer detects an abnormal voltage or resistance in the circuit associated with the driver's side window switch, it triggers this code. This can lead to several issues, such as the power window not functioning correctly, or the window may get stuck in an open or closed position. The real-world implication of this code is that it can affect the overall comfort and safety of the vehicle. If the window is stuck open, it could lead to interior damage from rain or theft risk. Moreover, if you notice that the window control switch is unresponsive, it’s crucial to address it promptly to avoid further electrical issues within the window system or even the vehicle’s electrical system as a whole. It’s recommended to conduct regular checks on your window switches and surrounds to ensure they are functioning properly, as neglecting this could lead to more expensive repairs down the line.

Symptoms

Common symptoms when B0460 is present:

  • The power window does not respond to the driver's control, making it impossible to open or close the window.
  • The driver's side window may operate intermittently, working sometimes and failing at others, leading to frustration.
  • You might notice the window motor making a clicking sound but not moving, indicating a potential issue with the switch or wiring.
  • The vehicle may trigger an additional warning light on the dashboard, indicating a broader electrical issue.
  • Increased power consumption may lead to a battery drain if the power window system is activated unintentionally.

Possible Causes

Most common causes of B0460 (ordered by frequency):

  1. The most common cause is a faulty power window switch, accounting for about 50% of cases. This may occur due to wear and tear or internal failure.
  2. Wiring issues, including frayed wires or corrosion at the connectors, can lead to the B0460 code. This is the second most common cause and can often be prevented by regular inspections.
  3. Poor connections in the window switch harness can also trigger this code. It’s important to ensure that all connections are clean and tight during routine maintenance.
  4. Less common but serious is a malfunctioning Body Control Module (BCM), which can affect multiple functions in the vehicle, including windows.
  5. A rare but possible cause is a short circuit in the window motor itself, creating an overload situation that can damage other electrical components.
