OBD code J1850 refers to a communication protocol used in vehicles, specifically related to the J1850 standard for vehicle bus communication. It typically indicates issues with the vehicle's communication network, which can affect data exchange between the engine control unit (ECU) and other modules. This code is often associated with older vehicles, particularly those from the late 1990s to early 2000s. Diagnosing the underlying issue may require checking wiring, connectors, and the functioning of the involved modules.

If the OBD-II code reader goes blank when plugged into the car, it could indicate a problem with the vehicle's OBD-II port, such as a blown fuse, loose connection, or lack of power supply. It may also suggest that the code reader itself is malfunctioning or not compatible with the vehicle. Additionally, some vehicles may require the ignition to be in the "on" position for the scanner to power up. Checking the connections and ensuring compatibility can help resolve the issue.
