Engine Controller Reprogramming (Reflash) - Polaris RANGER 1000 2020 Service Manual

GENERAL INFORMATION

ENGINE CONTROLLER REPROGRAMMING (REFLASH)

OVERVIEW
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 field provided on the Reflash
Authorization site. The Request Code is automatically
generated by Digital Wrench® during the reprogramming
process.
REPROGRAMMING (REFLASH) TIPS
• Check the Vehicle's Battery Voltage
Make sure the vehicle's battery voltage (no load) is at
minimum 12.8 volts (12.5 volts with the key ON). If
necessary, connect a battery charger to bring voltage
level above minimum.
• Use a Dedicated PC for Diagnostics Only
– Best results are obtained using a PC that is
dedicated to Digital Wrench® diagnostics only.
Running Digital Wrench® software on a PC that
includes other non-essential programs might affect
the software performance.
– Make sure the PC is plugged in and charging
before you attempt to reprogram.
– Avoid using the PC while reprogramming is in
progress.
• Understand the Process
Review the Digital Wrench® System Help before you
attempt to reprogram. See "Digital Wrench® Software
Overview" for information on how to access the
System Help.
