Smartcraft message

[wallyworld]

Hey Everyone.......Anyone know what the term..."Data bus"....means on the Smartcraft readout in the tach ? Unit is a 2004 MPI 350 Mag with a Bravo 3. After turning on the ignition data bus came up instead of the usuall....batteries and temp OK...etc. This happened on 2 on & off cycles of the ignition....then readout was back to normal on the next 3 or 4 tries. Engine fires up....(on trailer)...and all seems OK. Anyone got an opinion ?? Much thanks.

your dat bus is your main engine harness theres usually a clamp around it so it wont bounce loose remove check connection to see that there not green put a little dialectric grease align and re clamp
