V1 Crank Relearn via HPTuners

[jayrolls]

I tried to do the Crank relearn process via VCM scanner in HPTuners, however I’m not sure if it took or not. I’m not sure if the BCM plays any part in the process. The procedures state to engage the parking brake, which goes to the BCM. I don’t have my parking brake wired in so I don’t know if that matters. Does anyone have any clue if the BCM needs to see the parking brake signal for the crank relearn to work?

It shouldn’t. I skip that part every time I relearn my trucks.

Can you do a crank Relearn with just the HP tuner and the same with the Throttle position relearn

You can for the crank relearn, not sure about the throttle.
