The AFIS420VSX-B is a Fast Idle system that elevates engine idle RPM based on a number of “triggers”.
The vehicle must be in Park for Fast Idle to engage. There are three different engine RPM settings which
can be selected by grounding different control inputs. The three different RPM values can be independently
set during installation.
