Transmission was replaced on this vehicle, and it was not driving fine. Then I began to access the fault p0890: transmission control module using test lamp and I notice that there was no battery voltage to illuminate the test lamp on the TCM connector but there was ignition, so I have checked the fuse location that powers the TCM battery voltage line but I didn't see. I also used diagrams for a 2013 Nissan Rogue fuse box diagram, but they are not the same.
Please I need the TCM connector view, TCM wire diagram and fuse box diagram for this vehicle for me to solve this problem

The 2014 Nissan X-Trail displays three transmission-related diagnostic trouble codes:

P0890: This code indicates an issue with the Transmission Control Module (TCM) power relay sense circuit, suggesting a discrepancy in the battery voltage supplied to the TCM.

P0847: This code signifies a problem in the transmission fluid pressure sensor/switch "B" circuit, pointing to a low circuit condition in this system.

P084C: This code generally denotes an electrical issue within the transmission fluid pressure sensor (TFPS) sensor circuit.

To troubleshoot, consider replacing the TCM relay and then activate the system to detect a click, indicating proper function. If this occurs, proceed to have the TCM professionally tested. Below are the transmission wiring diagrams for further reference. Please keep us updated on the developments.

Thank you so far but you didn't include fuse box diagram to help me locate fuse #59.
Note: I also used diagrams for a 2013 Nissan Rogue fuse box diagram, but they are not the same. So, I am waiting for the fuse box diagram.
