What vehicles are most commonly affected by U098C?

U098C is frequently reported in models like the 2016-2020 Ford Explorer and Lincoln MKX, where complex electrical systems are more prevalent.

How can I prevent U098C from happening again?

Regular maintenance, including inspecting electrical connections and ensuring proper sealing against moisture, can help prevent future occurrences of U098C.

What is U098C?

DTC U098C is a diagnostic trouble code that indicates a communication issue between the Body Control Module (BCM) and the other control modules in your vehicle. Essentially, this code signals that the BCM has detected a malfunction or an inability to communicate properly with one or more components. This can lead to various symptoms, such as warning lights on the dashboard, issues with the vehicle's electrical system, or even problems with starting the vehicle. The underlying cause of U098C can vary widely, but it often points to wiring issues, faulty modules, or problems in the communication network. In real-world terms, if you see this code, it’s a signal to investigate further. Ignoring it could lead to more significant issues, like electrical failures that may affect your vehicle's performance or safety features. If you drive a 2016-2020 Ford Explorer or Lincoln MKX, you may be more susceptible to this code due to the complex electrical systems in these vehicles. Addressing U098C promptly is essential to maintain both the functionality and safety of your vehicle.

System: U - Network (Communication, CAN Bus)

Symptoms

Common symptoms when U098C is present:

The check engine light remains illuminated, indicating a persistent issue that needs addressing.
You may experience erratic behavior in the vehicle's electrical systems, such as power windows or lights not functioning.
Fuel economy could noticeably decrease, possibly around 10-15% due to accessory components failing to operate efficiently.
You might find that some features, like automatic door locks or remote start, are malfunctioning intermittently.
The vehicle may have difficulty starting, especially in cold conditions, due to the BCM's inability to communicate with the ignition system.

Possible Causes

Most common causes of U098C (ordered by frequency):

A common cause of U098C is damaged wiring or connectors, with a likelihood of around 40%. This can happen due to wear and tear or environmental factors.
Another possible cause is a faulty Body Control Module itself, which can occur in about 30% of cases. This could be due to internal failures or software glitches.
Corrosion in the connectors or terminals can also lead to communication issues, which is preventable through regular maintenance and inspection of electrical components.
Less commonly, issues with the vehicle’s main electrical harness can cause this code, which might require a detailed inspection to diagnose.
In rare cases, a software update or reprogramming of the BCM may be necessary to resolve the issue completely.
