What is B0675?

The diagnostic trouble code (DTC) B0675 indicates a malfunction within the power seat switch circuit, specifically linked to the seat adjustment system in vehicles. This code is particularly prevalent in Ford models produced between 2014 and 2020, including the Ford F-150 and Ford Explorer. When this code is triggered, it typically means that the power seat switch is not communicating properly with the seat control module. This could be due to a faulty switch, damaged wiring, or even issues within the seat module itself. As a result, drivers may experience difficulties adjusting their seats, which can lead to discomfort and safety concerns while driving. If left unresolved, this issue may also lead to further electrical problems within the vehicle, potentially impacting other systems that rely on the same wiring harness. Addressing the B0675 code promptly is crucial to ensure optimal vehicle performance, comfort, and safety. Understanding the implications of this code can help car owners make informed decisions about repairs and maintenance, ensuring their vehicle remains in top working condition.

Symptoms

Common symptoms when B0675 is present:

  • The power seat does not move forward or backward, which can hinder driver's ability to find a comfortable position.
  • The power seat switch may be unresponsive or intermittently functional, leading to frustration while trying to adjust seat position.
  • The seat position memory function fails to recall saved settings, which can be particularly inconvenient for multiple drivers.
  • The seat heater or cooling functions may also malfunction, as they share components with the power seat system.
  • The check engine light or other warning indicators may illuminate, indicating an underlying electrical issue.

Possible Causes

Most common causes of B0675 (ordered by frequency):

  1. The most common cause of the B0675 code is a faulty power seat switch, which accounts for approximately 50% of cases. This can arise from wear and tear or internal failures.
  2. Another likely cause is damaged wiring or connectors leading to the power seat module. Frayed wires or loose connections can disrupt signals.
  3. A malfunctioning power seat control module can also trigger this code, especially if the module has been exposed to moisture or has internal faults.
  4. Less common but serious causes include issues with the vehicle's body control module, which can affect multiple electronic systems in the car.
  5. In rare cases, a complete failure of the power seat assembly may occur, requiring a more extensive repair or replacement.
