The reprogramming feature is in the Special Tests menu
on the Digital Wrench® screen. Start Digital Wrench®
and click on the Special Tests menu icon (red tool box). A
technician should be familiar with the process and with
computer operation in general before attempting to
reprogram an ECU.
The Digital Wrench® Engine Controller Reprogramming
(or "Reflash") feature allows reprogramming of the ECU
fuel and ignition map. To successfully reprogram the
ECU, an Authorization Key must be obtained by entering
a Request Code in the box provided on the Reflash
Authorization site. The Request Code is automatically
generated by Digital Wrench® during the reprogramming
process. The Reflash Authorization site is located under
the "Service and Warranty" drop down menu on the
dealer website at: www.polarisdealers.com.
NOTE
Failure to follow the reprogramming instructions
completely and correctly can result in an engine that
does not run! Replacement ECUs are programmed as
"no-start" and require a reflash for them to work.
Reprogramming (Reflash) Tips:
• BATTERY VOLTAGE: The majority of problems with
reprogramming can be attributed to a low battery. Be
sure the battery voltage (no load) is at least 12.8 volts
and at least 12.5 volts with the key 'ON'. Connect a
battery charger if necessary to bring voltage level
above minimum. Fully charge the battery before you
attempt to reprogram.
• DEDICATED LAPTOP: Best results are obtained using
a laptop computer that is "dedicated to Digital
Wrench®. A laptop that is used by a variety of people
and in several applications around the dealership is
more likely to cause a reprogramming problem than
one dedicated to Digital Wrench® diagnostics only.
• OBTAINING THE LATEST UPDATE: Reprogramming
updates are provided periodically and contain the most
recent calibrations (see "Digital Wrench® Updates").
• CLOSE NON-ESSENTIAL PROGRAMS: Polaris
recommends that you DO NOT install non-essential
programs on a Service Department laptop. Camera
detection software, Virus Scanners, Tool Bars, etc.
may clog up memory if running in the background and
make it harder for the diagnostic software to operate.
• KNOW THE PROCESS: If you are not familiar with the
entire reprogramming process, review the HELP
section of the diagnostic software before you attempt
reprogramming. Click on the ? on the tool bar or press
F11. The information in the on-line help is the most
current and complete information available. This
should be your first step until you are familiar with the
process.

FUEL SYSTEM - GENERAL
• COMMUNICATION PROBLEMS: If you have had
problems communicating with a vehicle while
performing diagnostic functions, do not attempt
reprogramming until the cause has been identified and
fixed. Check all connections, and be sure battery
voltage is as specified.
• Proceed to http://polaris.diagsys.com for specific
information and FAQs on how to troubleshoot
communication problems.
• DON'T DISTURB THE PC: While reprogramming is in
progress, don't move the mouse and don't touch the
keyboard. The process only takes a few minutes, and
is best left alone until complete.
