Had a 2016 Mustang GT throwing P0315 after a rebuild and clutch install. The car had a real rough idle and would stall. The intake cams were very unstable and not in sync with each other, which could be why the crank relearns often fail.
I disabled "Variable Camshaft" in the top left of the variable camshaft tab which will "lock" the cams at their resting position, flashed the file.
Performed a crank relearn through VCM scanner, showed successful. P0315 cleared on its own.
Re-enabled VCT, flashed the file and TiVCT was fully functioning and running as it should.
I know this isn't a 100% working method, having tried crank relearn with the VCM Scanner on gt500s that already have the variable cam set to disabled with crank relearns failing. But after numerous attempts on a 5.0, this method worked first try.
