Preconditions for the test:
Ignition on.
No faults stored.
Note:
Used to adjust the idling contact.
Adjustment is only necessary when replacing the throttle unit or the lower part of the injection unit.
The idling contact can only be set when the pushrod of the throttle unit is fully extended. The pushrod is pushed out automatically when basic setting is initiated.
If the throttle is opened to gain access to the stop screw, the control unit moves the throttle pushrod back. To push the pushrod out again, the basic setting function must be chosen again.
When correcting the stop screw, the idling contact must be checked.
On quitting basic setting, the throttle unit pushrod must return to its initial position.
Procedure:
Choose the function: Adjusting the idling contact.
Read the throttle position sensor, track 1. Prescribed value 196-200.
If the prescribed values are not reached, remove the induction air cover and correct the setting with the stop screw. Setting value: 198 ± 1.
