Service Notes
• For more convenient and accurate testing of EFI
components, it is recommended dealers utilize the
Digital Wrench® Diagnostic Software (dealer
only), or testing may be done manually using the
procedures provided.
•
80% of all EFI problems are caused by wiring
harness connections.
• For the purpose of troubleshooting difficult running
issues, a known-good ECU from another RZR 800
EFI of the same model and year may be used
without damaging system or engine components.
• Never
attempt
to
service
any
fuel
system
component while engine is running or ignition
switch is "on."
• Cleanliness is essential and must be maintained at
all times when servicing or working on the EFI
system. Dirt, even in small quantities, can cause
significant problems.
• Do not use compressed air if the system is open.
Cover any parts removed and wrap any open
joints with plastic if they will remain open for any
length of time. New parts should be removed from
their protective packaging just prior to installation.
• Clean any connector before opening to prevent dirt
from entering the system.
• Although every precaution has been taken to
prevent water intrusion failure, avoid direct water
or spray contact with system components.
• Do not disconnect or reconnect the wiring harness
connector to the control unit or any individual
components with the ignition "on." This can send a
damaging voltage spike through the ECU.
• Do not allow the battery cables to touch opposing
terminals. When connecting battery cables attach
the positive (red) cable to positive (+) battery
terminal first, followed by negative (black) cable to
negative (-) battery terminal.
• Never start the engine when the cables are loose
or poorly connected to the battery terminals.
• Never disconnect battery while engine is running.
• Never use a battery boost-pack to start the engine.
• Do not charge battery with key switch "on."
• Always disconnect negative (-) battery cable lead
before charging battery.
• Always unplug ECU from the wire harness before
performing any welding on the unit.
