What is U0E98?

The U0E98 diagnostic trouble code (DTC) is a manufacturer-specific code associated with Ford vehicles, particularly prevalent in the 2017-2022 Ford F-150 models. This code indicates a communication issue within the vehicle's control modules, specifically related to the body control module (BCM) or communication lines between modules. When the U0E98 code is triggered, it signifies that the BCM is unable to communicate effectively with other modules, leading to potential malfunctions in various electrical systems, including lighting, climate control, and even safety features such as airbags. Vehicle owners may notice erratic behavior in their vehicle's electrical systems, which can range from simple issues like flickering lights to more serious concerns such as the failure of critical safety features. Ignoring this code can lead to more severe electrical problems down the line, as the modules rely on effective communication to function properly. Therefore, understanding and diagnosing this code is essential for maintaining the reliability and safety of your Ford F-150. If you've encountered the U0E98 code, it's crucial to address it promptly to avoid further complications and ensure your vehicle operates smoothly.

Symptoms

Common symptoms when U0E98 is present:

  • Check engine light illuminates and stays on, indicating a serious underlying issue.
  • Unresponsive electrical components, such as windows and locks, failing to operate correctly.
  • Erratic dashboard readings or warning lights that illuminate unexpectedly.
  • Inconsistent operation of safety features like airbags, which can be hazardous.
  • Decreased fuel efficiency due to potential drain on the electrical system.

Possible Causes

Most common causes of U0E98 (ordered by frequency):

  1. The most common cause is a faulty body control module, which has a likelihood of around 60%. A defective BCM may not send or receive signals properly, affecting various systems.
  2. Another common cause is damaged wiring or connectors, accounting for about 25% of cases. Corrosion or wear and tear can lead to poor electrical connections.
  3. A third cause could be software glitches within the vehicle's systems, which can sometimes be resolved with a simple software update.
  4. Less commonly, a malfunctioning or shorted-out sensor can trigger the U0E98 code, although this is rare.
  5. A rare but serious cause could be a complete failure of the vehicle's communication network, leading to widespread electrical failure.
