DESS (Digitally Encoded Security System) Description
This system is digitally encoded to provide you and your snowmobile
with the equivalent security as a conventional lock key.
The tether cord cap provided with your snowmobile contains an elec-
tronic chip in which a unique digital code is permanently memorized.
Your authorized SKI-DOO dealer programs this key code in the ECU
(Electronic Control Unit) of your snowmobile to allow engine opera-
tion above 3000 RPM if and only if this unique code has been read
after engine starting.
If a tether cord cap with different code is installed, the engine will start
but cannot reach drive pulley engagement speed to move vehicle.
Operation
See above for details.
Additional Tether Cord Caps
The ECU of your snowmobile can be programmed by your authorized
SKI-DOO dealer to accept 8 different key codes (tether cord caps).
We recommend the purchase of additional caps from your authorized
SKI-DOO dealer as additional keys. 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' keys.
