Yes manual can io does the job, what I was asking is that EBS unit in truck might send some of the trailer 24Vcan data through in to the truck 5V can network.
Wabco and Knorr brakesystems varies with different truck brands in their programming what they send through in different cases.
Just curious if some one has checked allready what common messages goes through.
Example VIN foof the connected trailer, or mileage for maintenance purposes.
But if no one has the info, I'll have to scan the can networks for different combinations of truck and trailer brands and work it out :D
