Hi, ok there can only be 2 termination resistors on a CAN Network (2008 up). Take a look at my newest OBD-2 Network tool, the OBD-II DLC Health Checker. www.autodiagnosticsandpublishing.com/OBD_2_DLC_Health_Checker.html

my 2015 jeep jk 3.6 only has 5 wires if i Rember correctly to DLC when i plug in CAN H AND LOW to my scope it only shows 2.5 x2 with math ch. total of 5v KOEO i dont get a normal can network signal. i think with engine running it will show a normal can network signal. any ideas? thx bob

I have tried several scanners, including the MB Star, Launch X431, Delphi as we ll as iCarsoft. Neither of them connect.
