Hi we have this electric Atlet 1Q2L25T
2011 YEAR AC same as the Nissan. Truck is totally dead the display doesn't light up.
Checked all fuses, have supply at keyswitch and bypassing the APO relay does power the truck display up with codes which proves display is ok. Replaced line contactor.

The traction controller phase mosfet was faulty so replaced both.

Still cant get the truck to power up. Really lost now as not sure what else to test for. Any advice would be greatly appreciated. Also cant see how the APO relats work as diagram doesn't show fees for the negative side of the relay and both relays just have a bridge on thw coil side which doesn't go anywhere else.

Thanks in advance.
