Hello,
Im trying to connect DDDEC V on bench but there is issue with the connection.
I got cable from internet i see there is J1708 and J1939 but i can not make any of the DDEC V to connect over J1708.
Ive see people connect to DDDL 6 and im wonder where could be the issue.
I have seen DDDEC V on DDDL8 but only faulty codes i just want to see parameters and calibration.
Probably the issue is on mine side but i could not find.
I have seen the ECMs has a voltage on Data lines but dont know why dont see in dddl6.
any help or drow or diagram will be perfect.
My cable has
J1708 (Pins 56-57)
J1939 (pins 58-43) - does not have a Ground Shield
Thank you !
