GENERAL
SYSTEM DESCRIPTION
NOTE: It is a good practice to check for fault
codes using B.U.D.S. software as a first trou-
bleshooting step. Refer to
COMMUNICATION
TOOLS AND B.U.D.S. SOFTWARE .
The D.E.S.S. system allows starting the engine
only with safety lanyard(s) that has been pro-
grammed to operate a specific watercraft.
NOTE: If desired, a D.E.S.S. key can be used on
other watercraft equipped with the D.E.S.S. It only
needs to be programmed for that watercraft.
The following components are specially designed
for this system: ECM, D.E.S.S. key and D.E.S.S.
post.
The D.E.S.S. key cap contains a magnet and a
ROM chip.
– The magnet actually closes the reed switches
inside the post which is the equivalent of a me-
chanical ON/OFF switch.
– The chip has a unique digital code which is the
equivalent of the notch pattern on a conven-
tional key.
The D.E.S.S. system is quite flexible. Up to 10 dif-
ferent keys may be programmed in the memory of
the ECM. They can also be erased individually.
The memory of the ECM is programmed to rec-
ognize the digital code of the D.E.S.S. key. The
programming is achieved with the B.U.D.S. soft-
ware.
D.E.S.S. Key Types
For best results, it is recommended to use the
D.E.S.S. key with the oval shaped float. It is iden-
tified as the iControl key.

In addition to the normal D.E.S.S. key, other spe-
cial keys can be programmed so that the vehicle
can be run only up to a limited speed. Such a fea-
ture is ideal for first time riders or renters.
The D.E.S.S. keys are color-coded to differentiate
them.

KEY TYPE
COLOR
Normal key YELLOW or BLACK
Learning key GREEN
Rental key
ORANGE
NOTE: When a Learning or a Rental key is used,
the DOCK MODE is always active. Refer to
SUS-
PENSION (iS)
subsection for more information
about DOCK MODE.
The Learning and Rental keys can be set through
5 settings to control the maximum watercraft
speed. Refer to
SETTING MAXIMUM SPEED
FOR LEARNING AND RENTAL KEYS
.
D.E.S.S. Key Beeper Codes
When a D.E.S.S. key is present on the vehicle
D.E.S.S. post while the START button is pressed,
the key is identified by the ECM and coded
beeper signals are emitted according to the key
recognition. See table:
