Throttle / Ignition Kill System - Polaris IQ 2007 Service Manual

Throttle / Ignition Kill System

System Overview
There are two methods for cutting the ignition on CFI systems.
The first is the software stop system. The software stop system
only applies to the throttle flipper switch. The software stop
system is activated when the throttle flipper switch is closed
(closed throttle), but the TPS (throttle plate position) is still
above idle. When this occurs, the ECU software will determine
the throttle cable is "stuck" and kill the ignition system.
The second system is the hardware stop system. The hardware
stop system is a direct ignition kill system. That is, whenever the
operator turns the key to off, pulls the tether, or pushes the safety
slap switch down, the ignition system is immediately killed.
