Well, I did try the forscan software. Seems great for ford and mazda etc.
Problem is, it won't see my elm327 BT, however it does see my maxi flash elite j2534 BT reprogramming interface.
So after some research on my bosses dime.

I found that a special elm327 is available for the forscan software which has a switch for the HS/MS can protocols.

So I will not be able to see what you see since I won't invest in a new elm right now, or probably ever again since I am buying my bosses old autel 908.
But from what I see on the forscan software, you should be able to see alot more than cheap apps such as torque pro, obd doctor and such.
Just the fact that it saw my j2534 means you can do PATS key reprogramming and more. Quite valuable for ford owners.
I kind of wondered why the PC version is free but you have to pay for the android version.
If the android version was free, I would be ordering a elm327 with switchable hs-ms as we speak as I like just taking my tablet and BT dongle wherever I go for quick diagnostics on the fly for my friends and family.
Anyway, with that flowchart I provided, which you probably can get with your alldata subscription, you should get joy out of that forscan software to find out if you do in fact have a PCM issue or just a range sensor or just a open/short wire somewhere.
Since you are a electronic technician, you and me should get right along.
I just fixed my sister radio amplifier in her lexus last weekend, Got to see my son, my mom too. Some idiot reversed jumped the battery, so I was able to get the lexus is 250 AWD car on the cheap as many modules blew out. It ended up being two 3amp 400v diodes that shorted. Got those for 49cents a piece, soldered them in and presto, metallica was blasting out of that sweet OEM pioneer amp. My sister was quite happy, she needs her tunes. The BT speaker I gave her, coupled with her smart phone was just not cutting it. It was funny hearing her rant and rave that I had to wait on those diodes. I told her to shut up, I found her a 12grand car for 7grand, so put up with it and shut up till I get up there to fix it. I have a life, and your tunes are the least of my worries with life and work going on.
It was an overall great weekend except for the six inches of snow in april that put a dent on things. Winter just does not want to go away this year. Global warming???? Not up here it ain't.
@ Diesel don, I know I am writing more than I should, but we could sure use an electrical technician here. So stay with us, we have use for guy's like you, and you never know, you may make internet buddies as I did here.
Great bunch of guy's, and no smoke usually blows out of our arses.
