Sequence of Opening Operation

Sequence of Opening Operation

When the "Open" request is sent by radio-control key or by a trunk button (TOEHK S117 or TOEHKI S8),the PM operates the trunk lid lock actuator(ZV).

The operating command is transferred by the K-CAN-P to the HKL which activates the pump in the "Open" direction. The pressure valve is still not activated, so the pressure in the hydraulic system is minimal. When the trunk lid lock is fully open, the contact inside of the ZV signals the PM.

This information is also transferred by bus to the HKL. Simultaneously as the SCA motor is being operated by the PM the HKL activates the opening operation. The pressure valve is closed and pressure is built up. The lid is now opened fully.




The HKL module detects the position of the trunk lid using the angle sensor.

Shortly before reaching the end stop "lid open"(transition from segment 7 to segment 8), trunk speed is reduced and the lid slowly moves to its end position.

If one of the control buttons is pressed again during the opening sequence, the operation is interrupted. Pressing the button once more resumes the sequence.

Operation of the automatic trunk lift is not allowed if the outside temperature (K-CAN-P signal originated by the Kombi) is below -30°C (-22°F).
