Question

I ran a diagnostic on a 2002 Ford Taurus and a U1262 came up what is this?

Answer 1

U1262 SCP communication on BUS fault

The moment you connect your scan tool to the OBD connection that scan tool becomes a host or better a module , just like the vehicle has a ECM (engine control module) a GEM (generic electric module) your scan tool is a host, or a module. This may be the scan tool that is setting this code. try using a different one.
