7. On the Backplane, there are four (4) LEDs that should blink when the IGV Motor is being driven. Refer
to Figure 4-50 Backplane IGV LEDs on page 85.
l
Check that all four (4) LEDs are blinking (D13, D14, D15, and D16) and that the IGV position
indicator ball moves toward open. Refer to Figure 4-42 IGV Connections on page 82 for the location
of the IGV Position Indicator.
NOTE
The LEDs will not remain illuminated once the requested position has been achieved..
