• 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
th
e 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.
• COMMUNICATION PROBLEMS: If you have had
pr
oblems 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 h
ttp://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.
