Circuit Operation

When the trunk lid is unlatched, the trunk lid latch switch moves to the UNLATCHED position and the trunk lid ajar switch moves to the LID MAR position. Since the striker switches are in position 1, the PULL DOWN fuse provides battery voltage to the striker motor through striker switch B. The striker motor runs, since the motor is grounded through striker switch C and the trunk lid ajar switch. The striker motor drives the striker up until the striker switches are moved to position 2. The striker motor will stop running, since the motor is no longer grounded through striker switch C.

When the trunk lid is open, the trunk lid ajar switch provides an input on CKT 744 (RED/BLK) informing the Body Control Module (PZM) the trunks ajar. The PZM then requests, by Class 2 serial data line, that the "TRUNK OPEN" message be displayed on the Driver Information Center (DIC).

When the trunk lid is latched, the trunk lid latch engages the striker and the trunk lid latch switch moves to the LATCHED position. Since the striker switches are in position 2, the PULL DOWN fuse provides battery voltage to the striker motor through striker switch B. The striker motor runs, since the motor is grounded through striker switch A and the trunk lid latch switch. The striker motor drives the striker down until the striker switches are moved to position 1. The striker motor will stop running, since the motor is no longer grounded through striker switch A. When the trunk lid is in the fully closed position the trunk lid ajar switch moves to the LID CLOSED position.
