running Vehicle Network toolbox.

modified the "Basic J1939 Communication Over CAN" example to use a database I have for a specific altentator used in a vehicle.

I port the data out using a Kvaser leaf lite v2 (actual HW) on a CAN buss

I see the data come out on bus....but the ID being boradcast is NOT EXACLTY the ID in the dbc...

example: the dbc file sends a message "Set_Point_Request", ID = 0x18ffa30f.....

on the can bus....I see the data....but the ID the kvaser is printing is 0x18ffa300...

?...I know it is something simple.....
