GENERAL
BASIC STARTING SYSTEM
OPERATION
Engine Cranking Conditions
The following conditions must be met to allow en-
gine cranking:
1. START/STOP button pressed and released to
activate the ECM.
2. The tether cord securely installed on the en-
gine cut-off switch and the D.E.S.S. k ey recog-
nized by the ECM as valid (2 short beeps)
3. START/STOP button pressed and held.
Starting System Logic
If the ECM recognizes a valid D.E.S.S. key, it al-
lows engine cranking by providing the ground to
the starter solenoid when the START/STOP but-
ton is pressed and held.
If the START/STOP button is activated while the
throttle lever is depressed more than 60%, the en-
gine will crank but will not start (engine drowned
mode).
If the START/STOP button is held after engine has
started, the ECM automatically stops the starter if
engine speed reaches at least 1400 RPM.
If the START/STOP button is pressed when the
engine is running, the engine will shut down.
Required Tools
To perform the tests in this subsection, the follow-
ing tools are required.

TROUBLESHOOTING
DIAGNOSTIC TIPS
NOTE: It is a good practice to check for fault
codes using the BRP diagnostic software
(BUDS2) as a first troubleshooting step. Refer to
DIAGNOSTIC AND FAULT CODES
subsection.
Starting system failures are not necessarily re-
lated to the starter but may be due to one the
following:
– Starter solenoid fuse F11
– Battery, refer to
CHARGING SYSTEM
–START/STOPswitch
– Starter solenoid
– Engine cut-off switch
–ECM
– Wiring/connections.
Check these components before removing the
starter.
NOTE: This subsection assumes the problem is
related to an electrical component of the starting
system. If the starting system tests good, ensure
engine and jet pump integrity. Refer to applicable
subsection.
