Manual open/close Operation

Note

•  Operation conditions vary depending on the vehicle conditions (Such as ignition switch, shift lever position). Refer to the operation conditions.

Manual open

1.  By operating the liftgate outer handle while the liftgate is closed, the liftgate outer handle switch turns on and a signal is sent to the PLG control module.

2.  When the PLG control module receives the signal, the operation conditions are confirmed, and if the conditions are met, a motor operation signal is sent to the closure motor.

3.  The closure motor rotates in the direction to open the liftgate and releases the latch.

4.  After the latch is released, the liftgate can be opened manually.

Manual close

1.  The liftgate can be closed manually in the same way as the previous liftgate.

2.  If the door is ajar, the half-latch switch turns off, and a signal is sent to the PLG control module.

3.  The PLG control module sends a motor operation signal to the closure motor.

4.  The closure motor rotates in the direction to close the liftgate, and the liftgate closes. The motor operates until a full-latch switch off signal is input.

Auto Open Operation

Auto open operation using the PLG front switch or transmitter operation

1.  While the liftgate is closed, a liftgate-open request signal is sent from the PLG front switch or the transmitter to the PLG control module.

2.  The PLG control module verifies the operation conditions after receiving the signal, and if the conditions are met, a buzzer sound is activated and a signal is sent to the BCM simultaneously to flash the hazard warning lights 2 times and to commence the open operation.

3.  The PLG control module sends a motor operation signal to the closure motor to release the latch.

4.  When the latch is released, the clutch in the PLG drive unit is engaged, and the PLG motor operates in the open direction.

5.  The PLG control module counts the pulse signals from the rotation sensor in the PLG drive unit to detect the liftgate speed. By detecting the speed, the PLG motor output is adjusted so that the liftgate opens smoothly at a constant speed.

6.  The PLG control module releases the clutch in the PLG drive unit when the counted pulse signals approach the fully open position.

Auto close operation using the PLG front switch, PLG rear switch or transmitter operation

1.  While the liftgate is open, a liftgate-close request signal is sent from the PLG front switch, PLG rear switch or the transmitter to the PLG control module.

2.  The PLG control module verifies the operation conditions after receiving the signal, and if the conditions are met, a buzzer sound is activated and a signal is sent to the BCM simultaneously to flash the hazard warning lights 2 times and to commence the close operation.

3.  The PLG control module counts the pulse signals from the rotation sensor in the PLG drive unit to detect the liftgate speed and opening angle. By detecting the speed, the PLG motor output is adjusted so that the liftgate closes smoothly at a constant speed.

4.  When the liftgate approaches the fully closed position, the half-latch switch turns off, and closure motor operates in the close direction. After this, the PLG motor stops and the clutch is released.

5.  The closure motor rotates in the direction to close the liftgate, and the liftgate closes. The motor operates until a full-latch switch off signal is input.

Emergency peration/stop

Reverse operation

•  If any of the following conditions are met during auto open/close operation, the buzzer sounds and the liftgate reverses its direction of operation.

―  The liftgate outer handle switch, PLG front switch, PLG rear switch, or the transmitter (PLG button) are operated

―  A touch sensor is activated and it is determined that an object is obstructing

―  There is no change in the rotation sensor pulse signal other than the fully open/closed positions, and it is determined that an object is obstructing.

Emergency stop

•  If any of the following conditions are met during auto open operation, the buzzer sounds and the liftgate stops immediately.

―  The power supply voltage is less than 8 V

―  A malfunction is detected in the rotation sensor, Over-current in PLG motor, PLG motor failure and ECU failure.

•  If any of the following conditions are met during auto close operation the liftgate stops immediately.

―  The power supply voltage is less than 8 V

―  A malfunction is detected in the rotation sensor, touch sensor, half-latch switch, or the full-latch switch, Over-current in PLG motor, PLG motor failure and ECU failure.

•  Insertion, turning over repetition.

Vehicle moves during auto operation or CAN system malfunction occurs

•  If the vehicle speed is 3 km/h or more during auto open operation, the operation is reversed and auto close operates until the liftgate is fully closed.

•  If the vehicle speed is 3 km/h or more during auto close operation, the auto close operation continues until the liftgate is fully closed.
