Common vehicles include 2015-2018 Ford F-150, certain Dodge Ram models, and some Chevrolet Silverado pickups. Always check for any recalls or technical service bulletins (TSBs) related to your vehicle.
How can I prevent U097E from happening again?
Regularly inspect wiring and connectors for wear, keep software updated through dealer services, and maintain good battery health to ensure stable voltage across systems.
What is U097E?
DTC U097E is a diagnostic trouble code that signifies a communication issue between various modules within a vehicle's network. This code typically indicates that the vehicle's control modules, such as the Transmission Control Module (TCM) or the Body Control Module (BCM), are not able to communicate effectively. When this occurs, it can lead to a variety of issues, including erratic performance, failure of certain electronic components, or even complete system failure. Owners of vehicles affected by this code may experience symptoms such as warning lights on the dashboard, problems with the transmission shifting, or features like power windows and locks malfunctioning. It’s crucial to address this issue promptly, as ignoring it can lead to more severe problems down the line, including potential safety hazards. In vehicles like the 2015-2018 Ford F-150, this DTC can also affect the Advanced Driver Assistance Systems (ADAS), impacting features like adaptive cruise control and lane-keeping assist. Understanding this code is essential for maintaining optimal vehicle performance and safety.
System: U - Network (Communication, CAN Bus)
Symptoms
Common symptoms when U097E is present:
- Check engine light stays on constantly, indicating a persistent issue that needs diagnostics.
- Engine hesitates during acceleration, making driving unpredictable and potentially dangerous.
- Fuel economy decreased by 10-15%, leading to higher operating costs and more frequent stops at the gas station.
- Power windows and locks may fail to operate correctly, impacting comfort and security.
- Transmission may shift erratically, causing a rough driving experience and increased wear on components.
Possible Causes
Most common causes of U097E (ordered by frequency):
- Faulty wiring or connectors (70% likelihood) – Damaged, corroded, or loose connections can prevent proper communication between modules.
- Software glitches in the control modules (20% likelihood) – Outdated or corrupted software can lead to communication errors.
- Malfunctioning control modules (5% likelihood) – A failing TCM or BCM may not send or receive signals correctly.
- Less common but serious cause: Short circuits in the vehicle’s electrical system could lead to extensive damage.
- Rare but possible cause: A factory recall or service bulletin related to the vehicle's communication systems.
