Limited throttle mode--The control module will continue to use the accelerator pedal for throttle control; however, the maximum throttle opening is limited.
Throttle default mode--The control module will turn off the throttle actuator motor and the throttle will return to the spring loaded default position.
Forced idle mode--The control module will perform the following actions:
Limit engine speed to idle by positioning throttle position, or by controlling fuel and spark if throttle is turned off.
Ignore accelerator pedal input.
Engine shutdown mode--The control module will disable fuel and de-energize the throttle actuator.
