Multiecuscan (MES) - PROXI Alignment Procedures

Here are the procedures to perform a PROXI alignment which is necessary when changing parameters in MultiECUScan (MES) that are not represented by Adjustment items (e.g., drop down menus).

First, if you haven’t done so already, verify that your computer is setup properly by reading the Multiecuscan User Guide Page 2. (Installation and License / Interfaces)

Without proper COM port settings, you may end up failing the PROXI alignment. READ THE MANUAL.
