I can't get an ECU read on my 2012 F-150 5.0.
I get an error when it says it's checking the ECU security then it says will retry in 12 seconds then says failed. I had a tune on the truck so I flashed back to stock with my other tuner and it does the same thing (I bought the truck new so i know these are the only tunes the truck has seen). At this time I notice that in vehicle details it has my truck as a 2012 sierra v8 but my VIN number is showing correctly.
I've tried unchecking the high-speed box and it does the same thing. I've tried other tunes as well and no change. My SCT tuner is changing tunes just fine so I know there's power to the OBDII port. Yes the Key is on. Device manager shows MPVI channel A and B using both UBS 2.0 and 3.0 ports. I'm using Windows 10 on a Lenono gaming laptop.
Thanks in advance.
