Power balance tests and a crank relearn, or cam/crank relearn are two totally different things. Power balance is a functional test to help determine misfire on a cylinder or group of cylinders. Crank relearn, or cam/crank relearn is a functional reset to relearn the actual position of cam and crank TDC position. Think of the difference as power balance test (pull a plug wire or coil connector ) to find a weak cylinder, and crank relearn, set timing or (remove #1 plug, find piston TDC) and set crank sensor to indicate actual top dead center of #1 piston on the compression stroke. Some PCM's have this function, some do not. If they do, we need to be able to perform this function with a proper scan tool.
I would hope that includes the Autel scan tools available for purchase.
