      I have to find out if there is a version for iPad, since I don't have a laptop, plus an adaptor for the diagnostic connecter that plugs into the Lightning connector on the iPad, or even better a Bluetooth adaptor. A year and a half ago I pulled the engine and replaced the entire timing gear/chain/guide system. To be honest that was almost easy compared to the aggravation this is causing!
      Thanks for all your help, Bob. I'll let you know how it goes when I investigate your links.

      I would try and reinitialize the PATS module to the ECU before spending any money on anything. Software and adapter is a 10 dollar investment.
      Looks like it's not to complicated.

      You are correct. I was getting frustrated.

      Looks like a WiFi adaptor is required for Apple devices. I saw the info on the Standard and Extended user agreements for Windows, I don't see anything for Apple OS. I need to find out first if there is a similar arrangement to get the extended license for the OS version I would think. FORScan is available in the Apple store for $4.95.

      I think you are going to need a Windows based pc or laptop. (Used ones are dirt cheap on ebay)
      Looks like apple and android won't do complicated reset or write functions.

      That is what I was thinking as well. Worse case is I'd have to buy one as you indicated if I can't find a friend to help.
      I'm holding off right now anyway. I found a '98 for sale in North Jersey that runs but the seller says it has transmission "issues". He accepted my offer for it. Once I get it here I will rob the PCM, PATS module, and ignition lock out of it and install everything in my truck. I might have to follow the instructions makuloco has on his youTube channel to clear out the PCM so it can relearn all the drivability parameters, we'll see. At lease I will have a parts truck sitting here. It's the base model, XL, too bad it's not an Eddie Bauer or Limited.

      So here's the story: I let the truck sit there with the battery disconnected for approx 5 days, I was busy doing other things and also bought another Explorer to rob the PCM, PATS module, and keys from. Just out of curiosity I tried to start my truck on Tuesday afternoon. It started right up. It's been starting and running fine since. I'm thinking that sitting with the battery disconnected accomplished the same result that happens with the radio, where it loses all the presets after a few days without power. Maculoco also has a procedure outlined on his YouTube channel for completely clearing out the PCM, I thought that only erased the drivability info, but it might work for the issue I had.
      Meanwhile I now have a presentable '98 XL sitting here, it is supposed to have a "bad" transmission. It starts and runs fine, drives fine and goes through all the gears fine too, until it gets up to operating temperature, then the trans starts to slip until it won't move at all. If I let it sit for 10 minutes it will engage and move again. I'll mess around with it at some point, I got it for $500.

      Nice. What engine is in the new one?

      The truck I just bought has the pushrod V6 in it.
      My victory was short-lived, it won't start today, which I expected to happen, which is why I didn't take it anywhere far away yesterday.
