Individual Flap Test (via Pushbutton Control Module N22)

Figure 1:

NOTE:
1. The display window in the A/C pushbutton control module (N22) will show the test step. Pressing the various buttons will activate the individual vacuum actuators. The LED on the depressed button lights up.
2. The temperature control is maintained during the duration of the test.

Preparation For Test:

NOTE: Two stage vacuum actuators function at full stroke (100%) only, if the long stroke (80%) and the short stroke (20%) are pressed.
Pressing the short stroke (20%) by itself does not change the flap position.
The blower motor will operate on 6 V during the test.
