The transmission job was done on this vehicle and the cause was that the CVT chain was broken, and it was replaced. So, I need the troubleshooting of this fault code, wire diagram and fuse box diagram to do the basic inspection.

The code P17F0 in a 2013 Nissan Pathfinder is related to an issue with the Continuously Variable Transmission (CVT). This code is known as a CVT judder code and indicates a major problem with belt slippage. It's often referred to as a "death code" for the transmission. To address this issue, the valve body needs to be dropped and the belt and pulleys inspected using a borescope. If no damage is detected, the valve body should be replaced. Potential causes for this code can include a faulty CVT assembly, an open or shorted CVT harness, or a poor electrical connection in the CVT circuit.

I need the wire diagram for the CVT assembly, both how to drop the valve, fuse box diagram and CVT connector view to do the troubleshooting.
