IGNITION CONTROL SYSTEM OVERVIEW

A software stop is used to determine the position of the throttle release switch. The software stop system is activated
when the throttle release switch is closed (closed throttle), but the TPS (Throttle Plate Position) is still above idle.
When this occurs, the ECU will determine the throttle cable is "stuck" and disable the ignition system.
To test the throttle lever, measure the resistance with the lever pushed / closed and compare results to those listed for
the throttle release switch.
Always verify the throttle lever freeplay is set to specification.
A hardware stop system is a direct ignition disable system. That is, whenever the operator turns the key to off, pulls the
tether, or pushes the auxiliary stop switch down, the ignition system is immediately disabled.

NOTES
The 16 volt ECU power circuit provides power to the Injectors,
Ignition Coils and system sensors.
The 14 volt critical power circuit provides power to the fuel pump,
electronic oil pump and EVES Learn Relay. The EVES Learn
Relay powers the EVES Actuator, instrumentation, headlights and
tail light.
The 14.4 volt chassis power circuit provides power to the hand
warmers, thumb warmer, and accessory DC power. The battery
charge relay powers the battery charge circuit.
This applies only on models equipped with an IDD and GPS
receiver. The GPS receiver is mounted to a bracket with two cable
ties. The hood bracket is located on the underside of the hood.
The GPS receiver must be mounted to the bracket with the
directional arrow pointed towards the front bumper.
