GENERAL
BASIC STARTING SYSTEM
OPERATION
Engine Cranking Conditions
The following conditions must be met to allow en-
gine cranking:
– The D.E.S.S. key must be on its post and rec-
ognized by the ECM as valid (2 short beeps)
– 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 reached at least 1400 RPM.
If the START/STOP button is pressed when en-
gine is running, the engine will be shut down.
TROUBLESHOOTING
DIAGNOSTIC TIPS
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
TEM/FAULT CODES
section.

Starting system failures are not necessarily re-
lated to the starter but may be due to one the
following:
– Starter solenoid fuse F4
CHARGING SYSTEM
– Battery. Refer to
– START/STOP switch
– Starter solenoid
– D.E.S.S. post
– ECM
– Wiring/connections.
Check these components before removing the
starter.
NOTE: This section assumes the problem is re-
lated to an electrical component of the starting
system. If starting system tests good, ensure en-
gine and jet pump integrity. Refer to applicable
section.
DIAGNOSTIC GUIDELINES
The following is provided to help in diagnosing the
probable source of troubles. It is a guideline and
it should not be assumed to list all possible prob-
lems.
ENGINE DOES NOT CRANK
1. D.E.S.S. operation non functional or wrong
D.E.S.S. key
- If 2 short beeps are not heard when pressing
the START/STOP button, refer to DIGITALLY EN-
CODED SECURITY SYSTEM.
2. Burnt fuse: battery, starting system
- Check wiring then replace fuse.
