DC-CFI Throttle/Ignition Disable System
System Overview
A software stop is used to determine the position of the
throttle releas
e 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
le
ver pushed/closed and compare results to those in
illustration.
Always verify the throttle lever freeplay is set to
s
pecification.
A 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.
