DIGITAL ENCODED SECURITY
SYSTEM (DESS)
The DESS is a deterrent against theft.
Factory
programmed
, the tether cord provided with
snowmobile is the only one that allows engine to
turn more than 2500 RPM. If a wrong tether cord
is installed the engine will start but will not reach
engagement speed required to move vehicle.
The snowmobile MPEM can be programmed to
allow the use of up to 8 tether cords. When 8 teth-
er cords have been programmed all cords must be
deleted from MPEM memory before others can
be added.
Each tether cord has a small magnet as well as a
small micro chip molded into the rubber cap. The
magnet will close a primary circuit in the electrical
system. This completes the circuit and allows the
MPEM to read the electronic number in the tether
cord when engine is started.
NOTE:
We do not program the tether cord! we
record the tether cord electronic number into the
MPEM memory.
The MPEM also handles data input such as; cus-
tomer name, delivery date and it record the hours
of operation.
After engine is started 2 beeps confirm that the
MPEM has recognized the tether cord. The vehi-
cle can be driven normally.
A beep every 3 seconds and DESS pilot lamp
blinking as same rate mean that a bad connection
has been detected. Vehicle can not be driven.
Refer to SKI-DOO MPEM Programmer Guide (P/N
480 1436 00) for proper procedure.
