Ecu Replacement; Engine Controller Reprogramming (Reflash) - Polaris 600 RUSH 2010 Manual

ECU Replacement

Use the ECU replacement feature whenever installing a
new service ECU on the vehicle. Follow the guided
procedures in Digital Wrench® to perform the ECU
replacement procedure.
NOTE: The ECU replacement function initializes the
new service ECU. Service ECUs cannot be reflashed
without first performing this procedure.
The procedure copies the model ID number from the
original ECU, and then copies it to the new service ECU.
IMPORTANT: The procedure cannot be reversed once
the model ID number is copied to the new service
ECU. The service ECU will forever retain the model ID
number copied on it using this procedure.
If communication with the original ECU cannot be
established, Digital Wrench® will guide the user through a
manual model ID selection procedure. Pay careful
attention to the model selected when using the manual
procedure.
Cleanfire Fuel Injection
After completing the ECU replacement procedure, reflash
the ECU with the current ECU calibration file for the
vehicle using the engine controller reprogramming
procedure.
NOTE: ECU replacement only copies the model ID
number to the new service ECU. Vehicle history and
calibration files are not copied over.

Engine Controller Reprogramming (Reflash)

Process Overview
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.
IMPORTANT: 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 13 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").
