F was the ONLY one that worked on 205.

What do you mean by "C and G didn't work" ???...voltage readings ???...C and G is the Radio and Driver Control Module...F is the SDM Module...the Airbag !!

Did not work as in didn't show a voltage between .2-.7. they just showed 0.00X. Sorry about my wording.

I don't why they would show zero...I really prefer using a scope than a DMM...I don't think all these modules are shorted to ground if just seeing 0 volts.

My snap on triton d-10 might have a labscope.
When this issue started happening, the security light would be solid while driving and the windows would not work. If it went away my driver control would work the driver window both ways, but the passenger window would only go down. My passenger control would make it go up but it wouldnt bring it down.
No idea if that is related.
I also have a fuel gauge issue but that is just a high voltage and its messed up somewhere in the wiring most likely due to the people who put the big fuel pumps in before I got the car.

I have a Verus Pro D10 and that has a scope so I'm sure your Triton has one but if you've never used it that is a different story...unless you can de pin each module wire one at a time or use that tool shown in the video it might not be so easy...many YouTube videos on Snap On lab scopes if you don't know how to use it...all your issues most likely related to the low speed bus.

plugged in the lab scope and it only shows .55 max and a flatline. This is for every one I plugged into.

I went out to a battery on my pickup and it showed 12.7 so I know the scanner works

Well if it shows basically 0 volts or flatline that would be a short to ground...plug in both combs and turn on the ignition (green start light on) and put the one lead on pin 2 at the DLC and the ground lead on the door hinge bolt...you should see what my low speed bus looks like...0-7 volt square wave...I'm on a 20 ms time base and I'm showing one "data packet"...the scanner and scope are 2 separate tools...I can't remember if you have ignition function and what modules can you or can't communicate with...if you can look at the modules on the low speed bus and if you can look at live data that means you are communicating !!
