Tailgate





Note! Pinch sensors (7/227 A and 7/227 B) are only found on vehicles manufactured up to and incl. structure week 200947.

Note! The market in Japan has Remote Keyless Entry (RKE) regardless of if the vehicle is equipped with keyless entry system or not. When the vehicle is not equipped with keyless entry system, the Remote Keyless Entry (RKE) communicates directly with Central electronic module (CEM). If the vehicle is equipped with keyless entry system, the Remote Keyless Entry (RKE) communicates via Keyless Vehicle Module (KVM).

There are three ways of opening the tailgate. The usual way is by using the handle on the outside of the tailgate. A press of the switch is enough to open the tailgate, on the condition that the central locking has been activated.
The second way is to press the button on the remote key for 1.5 seconds. The final way is to press the button inside by the driver's seat, this must also be depressed for 1.5 seconds.
By pressing in switch handle quickly 2 times the function is deactivated for Power Operated Tailgate Module (POT), and the tailgate can then be opened manually.
The tailgate can only be opened if the vehicle's speed is below 1 km/h. If the speed exceeds 1 km/h after an opening phase has been started, the tailgate will stop and disengage.
There is only one way of closing the tailgate electrically and that is with the switch on the lower edge of the tailgate. If the vehicle's speed exceeds 1 km/h after a closing phase has been started, the tailgate will continue to close.
The Power Operated Tailgate Module (POT) can open and close the tailgate at temperatures between -40 °C and +80 °C.
The system is based on hydraulic fluid being pumped between a tank and a cylinder with a piston in it. The fluid forces the piston to move and this motion operates the piston rod's extension on the tailgate.
The system has two fluid lines which cause different forces to act upon the tailgate depending on the movement stage. It is mainly a safety issue as the force must be less in the greatest entrapment risk area.
The load sensor (Hall sensor) is mounted on the hydraulic system's pressure valve on the hydraulic pump.
When the pressure valve opens at too high a pressure, the load sensor registers the pressure valve's movement.
The load sensor senses if the pressure in the system is abnormally high. In such a case, it is because the piston cannot move due to an object obstructing the tailgate.
If there is over pressure in the hydraulics when opening, the system switches off. If there is over pressure when closing, the tailgate reverses all the way to the fully open position again.
The system includes a motor that pulls in the last bit by means of a wire cable. When the first lock position sensor indicates that the tailgate is in the first lock position, the motor is activated and the tailgate is closed. When the fully open and fully closed sensors the indicate that the tailgate is closed, the motor is reversed to resume the position of the wire cable, therefore enabling a new closure. Another motor releases the tailgate when it is to be opened.
The system is transparent in that the tailgate can be operated manually if the vehicle should lose power. This is because the hydraulic system is equipped with a valve that, in certain circumstances, eliminates the force in the hydraulic cylinder. As the tailgate is also equipped with a traditional gas cylinder, operation is just as on a vehicle without Power Operated Tailgate Module (POT).
