Power Tailgate Opening

** - Primary switch signal received by PTGM via CAN bus (sent by IPM)

PTGM Opening procedure:

1.	Opening can be triggered after a signal is received from, driver-console switch, outside handle switch, remote Key (FOB)

2.	The latch will be released (by IPM) by actuation of latch motor.

3.	On latch release, the tailgate latch pops out of the striker.

4.	PTG module controls the tailgate motor in order to open the tailgate.

Opening angle of the tailgate is calculated by counting the input pulse signals from Hall sensor.

When the motor movement is restricted, the PTGM stops the tailgate motor movement due to obstacle detection.

Power Tailgate Closing

PTGM Closing procedure:

1.	Closing can be triggered after receiving a signal from, console (driver) switch, ouside handle switch, remote key (FOB), inner switch

2.	PTG module controls the tailgate motor in order to close the tailgate

3.	Closing angle of the tailgate is calculated by counting the input pulse signlas from hall sensor

4.	The tailgate latch engages with the striker and the latch is locked mechanically (Latch unlock → Latch lock)

5.	PTGM stops the tailgate motor operation after detecting the tailgate latch's secondary signal

6.	On detecting the latch's secondary signal, the power close unit (PCU) starts the contract (cinch) operation and stops after the latch lock signal is detected

7.	After contract operation is stopped, PCU is rewound until the PCU home position is reached

8.	The tailgate is completely closed and latch is fully locked

Learned/Calculated/Programmed positions

Maximum Point for Opening

Above this position a start in opening direction could make the tailgate move beyond the Maximum Basic Position and overload the mechanical system (hinges).

Therefore the start of an opening action above this point is disabled.

Anyway the tailgate moves beyond this point, if it has been started at a lower position.

Learned Mechanical End Position

This is the mechanical block position while opening and is considered to be 100% opening. During the first tailgate opening this position is learned.

After learning, the tailgate will not move beyond the Maximum Basic Position, which is defined by the Learned Mechanical Position
