Trunk / Liftgate: Description and Operation
Voltage to the Rear Liftgate Release system is available at all times through the LOCKS SEATS Circuit Breaker and the ORN (540) wire. Ground for the optional Remote Switch is through the ORN/BLK (434) wire and the Park/Neutral Position and Backup Lamp Switch. This Switch is closed when the Gear Selector Lever is in the PARK or NEUTRAL Position. This completes a ground circuit to the optional Remote Release Switch. Moving this switch completes the circuit by grounding the Rear Liftgate Lock/Latch Module through the BLK/WHT (651) wire, to the Park/Neutral Position and Backup Lamp Switch (Park/Neutral Contacts), to the ORN/BLK (434) wire, to the Liftgate Release Switch, to the LT GRN (1306) wire, then to the Module. This triggers the module to send an unlock signal to the release solenoids via the PPL (1305) wire.The standard Rear Liftgate Key Switch will work also with the Gear Selector Lever in the PARK or NEUTRAL Position also. The switch, connected to the Rear Door Key Lock, is connected to ground by the BLK (1450) wire. Turning the key causes the switch to close, completing the circuit to the module via the LT GRN (1306) wire. This triggers the module to send an unlock signal to the release solenoids via the PPL (1305) wire.
The Dutch Doors lock electronically. This is accomplished through the Liftgate Strut Switch located on the RH Liftgate Strut. When the Liftgate is open, the Switch is closed and Connected to ground. Upon closing the Liftgate, the switch opens disconnecting the BLK (1450) wire from the GRY (1148) wire. The GRY (1148) wire triggers the module to send a lock signal to the Rear Door Lock Solenoid through the WHT (1304) wire.
