What is C098B?

The DTC C098B refers to a specific diagnostic trouble code associated with the vehicle's stability control system, particularly focusing on the electronic control unit (ECU) that manages various aspects of vehicle dynamics. When this code appears, it often indicates that the system has detected an issue with the communication between the vehicle's stability control module and other electronic components. This can lead to safety concerns as it may affect traction control and anti-lock braking systems. In simpler terms, if you notice this code, your vehicle might not respond optimally during emergency maneuvers or slippery conditions, which could increase the risk of skids or loss of control. It's commonly seen in 2016-2020 Ford Fusion models, but can appear in various other makes and models that incorporate advanced electronic stability and traction control systems. Addressing this issue is crucial, as ignoring it could lead to further complications, and potentially result in costly repairs down the line. The ideal approach is to have the vehicle diagnosed promptly to ensure safe operation and prevent further damage to the electronic systems involved.

System: C - Chassis (ABS, Steering, Suspension)

Symptoms

Common symptoms when C098B is present:

  • Check engine light stays on constantly, indicating a persistent issue with the vehicle's stability control system.
  • Unusual behavior during acceleration, such as the engine hesitating or feeling unstable, particularly on wet or slippery roads.
  • Reduced effectiveness of anti-lock brakes, noticeable during hard braking situations where the brakes may not respond as expected.
  • Increased tire wear due to improper traction control engagement, leading to uneven wear patterns on tires.
  • Dashboard warning lights related to traction control or stability control systems illuminate, indicating a malfunction.

Possible Causes

Most common causes of C098B (ordered by frequency):

  1. The most common cause is a faulty stability control module, which occurs in about 40% of cases; issues may arise due to electrical faults or software glitches.
  2. Secondly, damaged wiring or loose connectors between the stability control module and related sensors can account for around 30% of instances, leading to intermittent communication failures.
  3. Improper vehicle maintenance, such as neglecting tire pressure checks and alignment, can cause the system to react unexpectedly, leading to C098B; regular checks are recommended.
  4. Less common but serious causes include a malfunctioning ABS module, which can severely impact braking performance and is critical to address immediately.
  5. Rarely, software issues in the vehicle's ECU may require updates from a dealer, which could be a time-consuming process but essential for system functionality.
