Yes, sorry for not being clearer. Your "CPP/PNP" PID results match mine, assuming of course that FORScan also reported "Neutral" for that PID when your gearshift lever was in "N".Just to clarify, you're saying your test verify my CPP/PNP results are as they should be?
I use a variety of tools, of which FORScan is one. I often write my own programs to do useful things too. Sometimes, I even connect directly to the vehicle (using any of my USB or Bluetooth scantools) and run terminal emulator software to send raw commands and get raw replies.Out of curiosity, how'd you manage this without FORScan?
I think FORScan's choice of "Neutral" and "Drive" for displaying that PID's 2 states is a rather poor one. It really should say "Park or Neutral" and "Not Park & Not Neutral" (or maybe "Reverse, Drive, 2nd, or 1st"), to better match how it really behaves! I hope my mention of these PIDs didn't derail you too much. They probably have little bearing on your specific problem at this point. I just think that it's good to have a solid understanding of how these PIDs respond, in the normal case, so that when things go wrong, they might be useful in the diagnosis.I guess I don't even understand what this PID is looking at. What is in Neutral or Drive?
It's hard to explain without things getting confusing and I fear that it would start to get too far OT, but I simply don't trust that "TR" PID with the voltage display in your FORScan Lite screenshots. The "TR3_V" PID, OTOH, seems to be reporting your gear selector position perfectly, per the transmission manuals I've seen.Further, you're saying CPP/NDS is likely similar to that Trans Range PID that is incorrectly labeled and/or not functional?
It's very interesting to see what you've discovered so far with the valve body. Looking forward to seeing/hearing more.
