What is B098C?

The B098C diagnostic trouble code (DTC) refers to an issue within the vehicle's body control module (BCM) related to the power seat adjustment system. This code indicates that the BCM has detected an abnormal condition when trying to communicate with the power seat motor. The power seat system is crucial for driver and passenger comfort, allowing adjustments for optimal seating position. When the B098C code is triggered, it may lead to issues such as the power seats not responding, being stuck in a specific position, or not adjusting at all. This can significantly affect the driving experience, as proper seating position is essential for safety and comfort. While this code may not immediately render the vehicle undrivable, it indicates that there is a malfunction that needs to be addressed. Ignoring this code can lead to more significant issues in the seating system or even affect other electronic components in modern vehicles like the 2017-2022 Honda CR-V or 2018-2020 Toyota Camry, where similar systems are implemented. Addressing this code promptly can prevent further electrical issues and ensure a safe driving environment.

System: B - Body (Airbags, Lighting, Security, Climate Control)

Symptoms

Common symptoms when B098C is present:

  • The check engine light may illuminate, indicating a problem with the power seat system.
  • Power seat adjustment buttons do not respond, leaving the seats stuck in a single position.
  • Unusual noises may be heard from the seat motors when attempting to make adjustments.
  • The seat may move erratically or fail to lock into position, impacting driver stability.
  • In some cases, the vehicle’s electronic systems may show intermittent malfunctions, indicating a broader electrical issue.

Possible Causes

Most common causes of B098C (ordered by frequency):

  1. The most common cause is a faulty power seat switch, which has a likelihood of around 40%. This can happen due to wear over time or exposure to moisture.
  2. Another common issue is a wiring problem, such as damaged or corroded connectors, which can disrupt communication between the BCM and power seat motors.
  3. A malfunctioning BCM itself can also trigger the B098C code, which is less common but should be tested if other components appear functional.
  4. In rare cases, a blown fuse can lead to this code, preventing power from reaching the seat adjustments.
  5. Some vehicles may have a software glitch in the BCM that can cause false readings, necessitating an update or reset.
