The IPC supplies ignition voltage to the rear compartment lid release switch via circuit 744 (RED/BLK). When the ignition switch is ON, the IPC monitors circuit 744 (RED/BLK) at connector C2 terminal B6. When the rear compartment lid is open the switch closes and circuit 744 (RED/BLK) is connected to grounded via circuit 850 (BLK). The IPC detects this ground condition for at least one second, the IPC displays this message.
