System Description

WARNING: This page is about a different car, the 2016 Infiniti QX80. However, it is still accessible from the selected car via links, so may be relevant.

Second seat power unlock switch can be operated regardless of the ignition switch position, because power supply is always supplied to second seat power unlock switch and power unlock relay.
Power unlock motor pulls seatback control wire, seatback folds down, seat lock unlocks, and second seat tilts up, when second seat power unlock switch is pressed.
