DIGITAL WRENCH™ OPERATION

Digital Wrench™ Diagnostic Software Overview

IMPORTANT: Refer to Section 2, 3 and 4 in the Instruction Manual provided in the Digital Wrench™ Diagnostic

Kit to install the Polaris Digital Wrench™ diagnostic software on your computer.

The Digital Wrench™ diagnostic software allows the technician to perform the following tests and observations:

• View or clear trouble codes
• Analyze real-time engine data
• Reflash ECU calibration files

• Perform guided diagnostic procedures
• Create customer service account records
• Perform output state control tests (on some

models)

Special Tools (also refer to page 4.2)

Diagnostic Software Version

Always use the mos t curren t vers ion of the Digit al

Wrench™ software to ensure you have the latest updates

or enhancements. New reprogramming files and guided

diagnostic procedures are added to these updates as they

become available. For information on how to determine if

you have th e latest up date avai lable, re fer to “Digital

Wrench™ Version and Update ID”.

ECU Replacement

Although the ne ed for ECU r eplacement is u nlikely, a

specific replacement procedure is required to ensure that

all essentia l da ta con tained within the original ECU is

transferred to the replacement ECU.

Refer to pro cedure and car efully follow all instruc tions

provided in Digital Wrench™.

Guided Diagnostic Available

Guided diagnostics are available within Digital Wrench™

for all supported Trouble Codes (that is, any fault that will

turn on the ‘Check Engine’ indicator).

In addition, guided diagnostics are also available for many

other electrical sub systems.

Diagnostic procedures are added to subsequent versions

of Digital Wrench™ as they become available. Check your

release version often and upgrade when available to be

sure you are using the most current software available.
