What is U0B87?
The DTC U0B87 code indicates a communication issue within the vehicle’s network, specifically related to the 'Gateway Module' or 'Communication Bus.' This trouble code is thrown when the vehicle's onboard diagnostic system detects that the modules responsible for communication are unable to exchange information effectively. In practical terms, this could lead to various malfunctions, such as inoperable features or warning lights, which can be frustrating and concerning for drivers. Commonly found in vehicles like the 2015-2019 Ford F-150, U0B87 may affect multiple systems, including the engine control unit, transmission control unit, and infotainment systems. Drivers may notice symptoms such as failure of electronic components, warning lights on the dashboard, or in some instances, loss of vehicle control if critical safety systems are affected. It’s essential to address this code promptly to prevent further complications and ensure the vehicle operates smoothly. Ignoring the U0B87 code can lead to more significant issues, including reduced vehicle performance and costly repairs down the line.
System: U - Network (Communication, CAN Bus)
