DESS (Digitally Encoded Security System) Key/Cut-Out Switch
Liquid Cooled Models
On these models, the tether cord cap is digitally encoded to provide
you and your snowmobile with the equivalent security of a conven-
tional lock key and its shuts off the engine preventing snowmobile
to runaway if the operator falls off the vehicle accidently.
The tether cord provided with your snowmobile contains an electron-
ic chip in its cap which features a unique permanently memorized
digital code. Your authorized SKI-DOO dealer programs this tether
cord in the ECM (Engine Control Module) of your snowmobile to al-
low engine operation above 3000 RPM if and only if this unique code
has been read after engine starting.
If another tether cord is installed, the engine will start but will not
reach drive pulley engagement speed to move vehicle.
Additional Tether Cords
The ECM of your snowmobile can be programmed by your autho-
rized SKI-DOO dealer to accept 8 different tether cords.
We recommend the purchase of additional tether cords from your au-
thorized SKI-DOO dealer. If you have more than one DESS-equipped
SKI-DOO snowmobile, each can be programmed by your authorized
SKI-DOO dealer to accept the other vehicles tether cords.
DESS Pilot Lamp Codes
DESS pilot lamp blinking slowly (one time per 1.5 seconds) means
that a bad connection has been detected. Vehicle can not be driven.
To check for bad connection, remove. Make sure the tether cord is
free of dirt or snow. Reinstall cap and restart engine. If a blink per
1.5 seconds still occurs contact an authorized dealer.
