What is B0624?

The diagnostic trouble code (DTC) B0624 indicates a malfunction in the power seat control circuit. This code is commonly found in various vehicles, particularly in models from manufacturers like Ford, Chevrolet, and Honda, especially in models produced between 2010 and 2020. When B0624 is triggered, it typically points to issues within the wiring or components that control the power seat adjustment functionality. This can manifest as the power seat not moving at all, or moving erratically, which can be frustrating for drivers who rely on this feature for optimal comfort and safety. In some cases, the seat may become stuck in one position, which can hinder the driver's ability to maintain a proper driving position. The cause can range from a simple wiring issue to a faulty seat control module. Understanding this code is crucial as it directly impacts vehicle comfort and can potentially affect driving safety, especially if the driver's seat is improperly adjusted. Therefore, addressing the B0624 code should be a priority for any vehicle owner experiencing related symptoms.

Symptoms

Common symptoms when B0624 is present:

  • The power seat does not move when the controls are activated, indicating a possible electrical issue.
  • Seat movement is erratic, with the seat moving unexpectedly or stopping mid-adjustment, affecting driving comfort.
  • Warning lights may illuminate on the dashboard, alerting the driver to a potential issue with the seat adjustment system.
  • The seat may become stuck in one position, making it difficult to find a comfortable driving posture.
  • Some vehicles may experience intermittent functionality, where the seat works sporadically, creating uncertainty during adjustments.

Possible Causes

Most common causes of B0624 (ordered by frequency):

  1. The most common cause of B0624 is a damaged or frayed wire in the power seat circuit, with a likelihood of about 40%. This can occur due to wear and tear over time.
  2. A faulty power seat control module is another frequent culprit, accounting for around 30% of cases. This module may fail due to electrical surges or internal failures.
  3. Corrosion at the connectors or terminals can also lead to this code, with a prevention tip being to regularly check and clean these connections to avoid moisture buildup.
  4. Less common but serious causes include a malfunctioning body control module (BCM), which can prevent proper communication between the seat controls and the vehicle's electronic systems.
  5. A rare cause might be a blown fuse, which should be checked as part of the diagnostic process. Although infrequent, it can easily be remedied.
