PCM/ECU problems

Just installed a exchange PCM to fix an intermittent start issue. Starting issue seems corrected. But new issue is the engine light is on. OBD reader displays a the code "P0315 Crankshaft Position System Variation Not Learned". I've driven the truck over 10 miles still have the code. I have a 2012 with a 2.9L 4 cly.

Doing a quick search it seems it needs hooked to a scan tool to perform the relearn.
