ELECTRONIC THROTTLE CONTROL
(ETC) SWITCH
Operation Overview
The Electronic Throttle Control (ETC) system is designed to
stop the engine of an ATV in the event of a mechanical problem
with the throttle mechanism. The ETC switch is mounted
independently of the throttle actuator lever inside the throttle
block assembly. This is a normally closed switch, and is held in
the open position (contacts are separated (as shown below) by
throttle cable tension. The contacts are open" during normal
operation regardless of throttle lever position. In the event of a
mechanical problem in the throttle mechanism (cable tension is
lost), the switch contacts close, connecting the black wire to
ground, which prevents ignition spark. This is the same as
turning the key or engine stop switch “OFF”.
NOTE:
Test the ETC switch at the harness
connector. ETC will not activate unless there is
throttle plate movement off of “zero” detected by the
ECM. Adjust throttle cable freeplay (ETC switch) and
make sure throttle mechanism is functioning
properly before testing the switch. Refer to
Maintenance Chapter 2 for cable adjustment
procedure.
ETC Test
1.
Remove throttle block cover by carefully releasing all tabs
around edge of cover.
2.
Place transmission in neutral and apply parking brake.
3.
Start engine and open throttle lever slightly until engine
RPM is just above idle speed.
4.
Hold throttle cable with fingers at point “A” as shown
below and release throttle lever. If the ETC system is
functioning properly, the engine will lose spark and stop.
