Section 08 ENGINE MANAGEMENT (4-TEC)
Subsection 01 (OVERVIEW)
Limp Home Modes
Besides the signals as seen above, the ECM may
automatically uses default parameters for the en-
gine management to ensure the adequate opera-
tion of the watercraft if a component of the fuel
injection system is not operating properly.
The following components failure will trigger a
limp home mode: CTS, EGTS, OPS, OSPS and
TOPS.
When minor fault occurs, the fault and message/
beeper will disappear automatically, if the condi-
tion does not exist anymore.
Releasing throttle and letting the engine returning
at idle speed may allow normal operation to come
back. If it does not work, try removing and rein-
stalling the safety lanyard on its post.
Depending on the malfunction, the watercraft
speed may be reduced and not allowed to reach
its usual top speed. The engine speed will be
limited to 2500 or 5000 RPM.
These performance-reduced modes allow the rid-
er to go back home which would not be possible
without this advanced system. Refer to the DIAG-
NOSTIC PROCEDURES for a complete chart.
If a fault occurs and involves a limp home mode
operation, the engine management system will re-
duce engine RPM gradually to the proper level.
Diagnostic Mode
The malfunctions are recorded in the memory
of the ECM. The memory of the ECM can be
checked using the VCK (Vehicle Communication
Kit)(P/N 529 035 981) to see the fault codes.
The ECM and the VCK are able to communicate
through a connector on the vehicle. Refer to the
DIAGNOSTIC PROCEDURES section.
