Diagnostic Software Version
Always use the most current version of the Digital 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 the latest update
available, refer to “Digital Wrench™ Version and Update ID”.
ECU Replacement
Although the need for ECU replacement is unlikely, a specific
replacement procedure is required to ensure that all essential
data contained within the original ECU is transferred to the
replacement ECU.
Refer to procedure and carefully follow all instructions 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.
