Here G-scan2 will show you massage as below:
Each time after repair work has been carried out on the Valvetronics system,the limit posiitons on the adjusting mechanism must be relearnt for minimum and maximum lift.

During the teaching process,the eccentric shaft is turned slowly in the direction of minimum lift until a point of mechanical resistance is reached.

This position at the mechanical limit position is stored.
The same procedure applies to the maximum lift limit position.
