What is U0B97?
DTC U0B97 is a diagnostic trouble code that indicates a communication issue related to the vehicle's network. This code can specifically arise when the vehicle's control modules are unable to communicate effectively with each other, often due to problems in the data bus or issues within a specific module. In simpler terms, it’s like a conversation between different parts of your vehicle that has been interrupted or miscommunicated. For instance, if your Ford F-150 from 2015 to 2020 displays this code, it might lead to various malfunctions, including failure of advanced features like lane assist or adaptive cruise control, as these systems rely on data sharing between modules. Ignoring this code can lead to more significant issues over time, including potential safety hazards and reduced vehicle performance. Therefore, addressing the U0B97 code promptly is essential for maintaining the integrity of your vehicle's operation and safety features.
System: U - Network (Communication, CAN Bus)
Symptoms
Common symptoms when U0B97 is present:
- The check engine light remains illuminated, indicating a persistent issue that needs attention.
- You may experience erratic behavior in electronic features, such as unexpected activation of the traction control system or erratic speedometer readings.
- Fuel economy might decrease significantly, with reports of 10-20% reduced efficiency as the engine struggles with module communication.
- The vehicle may exhibit stalling or hesitation during acceleration due to miscommunication between the engine control module and other components.
- Advanced driver-assistance systems like blind-spot monitoring may fail to operate correctly.
Possible Causes
Most common causes of U0B97 (ordered by frequency):
- The most common cause of DTC U0B97 is a faulty wiring connection or damaged wiring, which occurs in approximately 40% of cases. This can happen due to wear and tear or exposure to elements.
