Anytime I have a communication issue, I start by checking powers and grounds to the non-communicating module. The I see if I can communicate to any other modules on the same bus. If I can't, I scope the bus to see if it has a short. If I can communicate to other modules, then I try a different scanner just in case. If I still can't communicate, I check the 5 volt reference to see if it's present and/or shorted.

reminds me of the break out box for older fords. I'm also running into comm issues and with fords i push in the lighter or probe it for power. I can't even begin to tell how many fords i work on that have been to other shops and when i ask the owner if the check engine light is on they say no and the other shops say that there are no codes. It's at the point when i walk out to it to scan it i carry a pocket screw driver an a 15 amp fuse. I'm seeing fuses missing as well.

this tool looks a bit interesting, not that i'm a tool whore or anything. I'm in the process of moving my office around a bit and i'm going to store my little toy tools in it so i can tinker around with them. I'm easily entertained. :lol: :lol: :lol:
