What is U0982?
The diagnostic trouble code (DTC) U0982 indicates a communication error between control modules, specifically related to the vehicle's communication network. This error often arises in vehicles like the 2015-2019 Ford F-150 and certain Chevrolet Silverado models. When this code appears, it signifies that one of the electronic control units (ECUs) is unable to communicate effectively with other modules in the vehicle. In practical terms, this can lead to various malfunctions, including issues with the anti-lock braking system (ABS), airbag deployment, or even engine performance problems. The underlying cause of U0982 can vary, but common issues include damaged wiring, faulty connectors, or software glitches in the control modules. If left unaddressed, this code can lead to more significant problems, such as safety features being disabled or reduced engine performance, making it essential for car owners to diagnose and repair the issue promptly.
System: U - Network (Communication, CAN Bus)
Symptoms
Common symptoms when U0982 is present:
- Check engine light remains illuminated, indicating a malfunction.
- Intermittent ABS warning light activation, which may lead to brake system issues.
- Inconsistent performance of electronic features like power windows and locks.
- Unresponsive dashboard indicators or warning lights that don't function as expected.
- Loss of power steering assist, making the vehicle difficult to maneuver.
Possible Causes
Most common causes of U0982 (ordered by frequency):
- The most common cause is damaged wiring or loose connections, with a likelihood of about 60%. Regular inspection can help prevent this.
- A software glitch in the control modules may also trigger U0982, especially after a recent update or vehicle service.
- Faulty control modules themselves can lead to this error, often requiring replacement for resolution.
- Less common issues include water intrusion or corrosion in connectors, which can disrupt communication.
- Rarely, a factory recall may address a systemic issue causing U0982, so checking for recalls is advisable.
