What is B1561?

The Diagnostic Trouble Code (DTC) B1561 indicates a malfunction in the power window switch circuit, particularly in vehicles like the Honda Accord manufactured between 2008 and 2012. This code suggests that the Body Control Module (BCM) has detected an issue with the input signal from the driver's side power window switch. In simpler terms, if you're experiencing problems with your windows not operating correctly, such as not rolling up or down, this code could be the culprit. The power window system relies on various components, including the switch itself, wiring, and the BCM. If the switch is faulty, stuck, or if there’s a wiring issue, the BCM will generate this code to alert you of the problem. Ignoring this code can lead to more significant electrical issues and could potentially compromise the safety of your vehicle, as operational windows are crucial for ventilation and emergency egress. Therefore, understanding and addressing DTC B1561 promptly is essential for maintaining your vehicle's functionality and safety.

Symptoms

Common symptoms when B1561 is present:

  • The power windows fail to respond when the switch is pressed, leaving you unable to operate them from the driver's side.
  • Intermittent window operation, where the windows sometimes work and sometimes do not, creating frustration for the driver.
  • The driver's side window may make unusual noises, such as clicking or grinding, indicating a potential mechanical or electrical failure.
  • Inconsistent behavior of the window lock function, where the locks do not engage or disengage as expected when the switch is used.
  • The vehicle’s interior lights may flicker or dim when attempting to operate the power windows, indicating electrical issues.

Possible Causes

Most common causes of B1561 (ordered by frequency):

  1. The most common cause of DTC B1561 is a faulty power window switch, which has a likelihood of 60%. This can often be identified by testing the switch for continuity.
  2. A second potential cause is damaged wiring or connectors in the power window circuit, which can disrupt the signal between the switch and the BCM.
  3. Wear and tear from age can lead to corrosion at the switch or connector, which can be prevented with regular inspections and cleaning.
  4. Less common but serious is a malfunctioning Body Control Module (BCM), which can lead to multiple electrical faults in the vehicle.
  5. A rare cause could be water ingress in the switch assembly, often due to leaks, which can cause electrical shorts and failures in the system.
