Here is what have been tried but failed!

Try to connect whit J1939…..same issue

 

On truck does not even get the engine and the others only couple line and very slow, might be some thing with them trucks

 

some things odd2006 models connect through J1939 and works.
Tryed on 3 trucks already that are 2005 and older the connect thought J1708 it says engine 128
And when doing the J 1939 test on them it says something like data error

 

Check the driver is installed well

J1939 & J1708 are added to the software

 

Finally, SOLVED!

The solution is this, connect, then scan to diagnostic connector but not to USB, open the Cummins insite and push connect, when the Insite begin to connect, immediately connect the USB and ready….
