Trunk / Liftgate: Description and Operation

Voltage is applied at all times through the RH Underhood Fuse Block Fuse 7 and Relay Center Fuse 1 to the Pull-Down Unit terminal A. When the trunk lid is opened the trunk open/closed switch moves to the OPEN position and the Trunk Lid Latch Switch moves to the UNLATCHED position. The striker switches are as shown in the schematic (STRIKER DOWN). Battery voltage is applied through the center striker switch to the striker motor. The striker motor is grounded through the right striker switch and the trunk open/closed switch to ground. The striker motor drives the lock striker up to prepare for closing. When the lock striker is fully extended the striker switches move to the STRIKER EXTENDED position. Battery voltage is applied to the striker motor in the opposite direction through the center striker switch. When the trunk lid is closed the striker motor is grounded through the left striker switch and the Trunk Lid Latch Switch. The striker motor drives the lock striker down and the trunk lid closes. The striker switches move to the STRIKER DOWN position and the trunk open/closed switch moves to the TRUNK CLOSED position. This removes ground from the striker motor and stops the striker motor from running.
