What is U0980?

The DTC U0980 refers to a communication error between the vehicle's control modules, specifically indicating an issue with the 'Communication Bus'. This code is prevalent in various 2015-2020 Ford models, including the Ford F-150 and Ford Explorer. When this code triggers, it often suggests that one of the modules is not communicating properly with the others, which can lead to various performance issues. A vehicle's control modules are responsible for managing different systems, such as engine management, transmission functions, and even safety features. If these modules cannot communicate effectively, it can result in symptoms such as erratic engine performance, failure of safety systems like ABS or airbags, and even potential stalling of the vehicle. Long-term neglect of this issue can lead to more severe damage and costly repairs, as the modules may fail completely. It's essential to address the U0980 code promptly to ensure safe and reliable vehicle operation.

System: U - Network (Communication, CAN Bus)

Symptoms

Common symptoms when U0980 is present:

  • Check engine light is illuminated and remains on, indicating a persistent issue.
  • Erratic or inconsistent engine performance, such as stalling or hesitation during acceleration.
  • Safety features, such as the anti-lock braking system (ABS) or airbags, may be inoperative, posing potential safety risks.
  • Decreased fuel efficiency, which can be noted by a drop of 5-10% in miles per gallon (MPG).
  • Absence of power to certain electrical components, such as windows or radio, which may fail to operate properly.

Possible Causes

Most common causes of U0980 (ordered by frequency):

  1. Faulty wiring or connectors is the most common cause, accounting for about 40% of cases, often due to wear and tear or corrosion.
  2. A malfunctioning control module may also lead to this code, usually due to software issues or internal hardware faults.
  3. Poor battery connections can cause communication interruptions; ensuring battery terminals are clean and secure can prevent this.
  4. Less common causes include damage from external factors, such as water intrusion in the module, which can lead to severe electrical issues.
  5. Rarely, updates or recalls may exist for specific models that address this communication issue, so checking with your dealer for TSBs is advisable.
