  • The mounting of control motor -1- can only be fitted on actuating arm -2- in one particular position.
The mounting of the control motor must be opposite to the actuating arm as shown in illustration. Note Rotate the receptacle in the control motor if the mount and actuating arm do not align.
  • Switch on ignition, connect respective control motor to vehicle wiring harness and select a setting on operating and display unit to set control motor to desired position (e.g. mid-position). Wait until control motor has moved to desired position and switch off ignition.
  • Fit control motor on air intake box. The actuating arm -2- must engage in mounting -1- while doing so.
There must not be any play in the connection between control motor and actuating lever. Note If the bolts cannot be fitted, the control motor is not completely seated on the housing.
  • Route wiring harness so that it cannot come into contact with any moving parts (e.g. actuating arm on control motor).
Note Turn the control motor until it reaches a convenient position for installation. The direction of rotation can be changed by changing polarities.
  • Read event memory, and clear any entries displayed. Then, perform “basic setting”vehicle diagnostic tester in “Guided fault finding” mode.
