Tree98, some gremlins are running around in my truck and are laughing at me lol. So like I mentioned the in-line 5 works and I was able to figure out why my Jake brake is not working on my n 14. It’s neat that you can see things like the clutch switch position and switches on/off on the dash! I’m pretty excited to have this tool.
So I tried doing a little trouble shooting on the in-line 5… I grabbed a couple wires and hooked the 9 pin j 1939 adapter that came with the in-line 5 and hooked up the serial end to the in-line 5 and put a hot and ground off a battery and the lights came on, on the in-line 5 (power light).
1.So I feel at this point I eliminated that the j1939 adapter cord and the in-line could be bad.
2.I have 12v at the 9 pin j1939 connector on the dash.

The only thing I can figure at this point (it’s dark out now) is the pins are not making a connection between the male and female 9pin j1939. I’ll try more tomorrow. I m hoping that’s all it is. Kinda like having to spread the connectors on a trailer connection.

On the CM870 vehicle ..
Why did you not just connect the adapter to the round duetch connector under the left side of the dash of the vehicle like most every one else uses>?.

also.. in Insite, make sure you have J1939 selected at the bottom as the connection type, instead of J1708.
