NOTE: Make sure transmission linkage is adjusted correctly or disconnect linkage rods before testing switch.
Inspect wiring between switch and terminal board and repair or replace if damaged. Replace the switch if battery
voltage is not indicated or if voltage is present when the selector is moved out of the specific range.
Electronic Throttle Control (ETC) Switch
The Emergency Throttle Control (ETC) system is designed to limit the engine RPM of an ATV in the event of a
mechanical problem with the throttle mechanism. The ETC switch is mounted independently of the throttle actua-
tor lever inside the throttle block assembly. This is a normally closed switch, and is held in the open position (micro
switch button depressed) by throttle cable tension. The switch is "open" in 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 (switch pin released) and deliver power to the Speed Limiter module via the white wire.
Test the ETC switch at the terminal board or harness connector. NOTE: Adjust throttle cable freeplay (ETC switch)
and make sure throttle mechanism is functioning properly before testing switch. Refer to Maintenance Chapter 2 for
procedure. Terminal board models - Disconnect White wire on terminal board that leads from the ETC switch. Turn
nition key (and e 19ine stop switc h) "On". If voltag
ig e is present on the White wire, replace the ETC switch.
