Service Notes

• For more convenient and accurate testing of EFI
components, it is recommended dealers utilize the
Polaris Diagnostic Software (dealer only), or
testing may be
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 Polaris
ATV EFI of the same model 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.
