VAUX-COM can also operate Relays, Injectors, EGR valves, Manifold Swirl Flaps, Lights, Motors, Solenoids and other Actuators to help test systems.
This video shows VAUX-COM operating the throttle butterfly on a 2005 Corsa C engine (Z12XEP).

2
00:00:05.254 --> 00:00:07.431
and looking at live data in measuring blocks.
3
00:00:07.431 --> 00:00:09.995
We can use output tests in VAUX-COM
4
00:00:09.995 --> 00:00:12.775
to control items on the car for testing.
5
00:00:12.775 --> 00:00:15.293
For example, on this Corsa C,
6
00:00:15.293 --> 00:00:17.207
the throttle butterfly is controlled
7
00:00:17.207 --> 00:00:19.334
by the car's own ECU.
8
00:00:19.334 --> 00:00:21.416
So by using Output Tests,
9
00:00:21.416 --> 00:00:23.227
we can control the throttle butterfly
10
00:00:23.227 --> 00:00:24.919
and then monitor its movement
11
00:00:24.919 --> 00:00:27.374
and the feedback from the two potentiometers
12
00:00:27.374 --> 00:00:30.207
built within the throttle housing.
13
00:00:31.227 --> 00:00:33.045
Live data is displayed, showing the throttle
14
00:00:33.045 --> 00:00:34.901
butterflies current position,
15
00:00:34.901 --> 00:00:36.198
and the feedback from each
16
00:00:36.198 --> 00:00:38.653
of the throttle position sensors.
17
00:00:38.653 --> 00:00:40.529
You can see that throttle position sensor one,
18
00:00:40.529 --> 00:00:42.284
is at its minimum value.
19
00:00:42.284 --> 00:00:43.750
And throttle position sensor two,
20
00:00:43.750 --> 00:00:46.123
is at its maximum value.
21
00:00:46.123 --> 00:00:47.841
When I click start activation,
22
00:00:47.841 --> 00:00:49.564
the throttle butterfly will be moved
23
00:00:49.564 --> 00:00:51.284
to its fully open position.
24
00:00:51.284 --> 00:00:54.433
Throttle position sensor 1 should go to maximum.
25
00:00:54.433 --> 00:00:57.626
Throttle position sensor 2 should go to minimum.
26
00:00:57.626 --> 00:00:59.018
And the calculated throttle position
27
00:00:59.018 --> 00:01:03.018
should go to 100% or very nearly 100%.
28
00:01:07.329 --> 00:01:10.228
(throttle opens)
29
00:01:10.228 --> 00:01:12.368
And then when I click stop activation,
30
00:01:12.368 --> 00:01:15.908
it should return to its rest position.
31
00:01:15.908 --> 00:01:18.741
(throttle closes)
