MSD Race Ignition
Test Tool PN 89973
OPERATION
A Master unit is a designated unit the Test Tool uses to validate other units are in compliance.
Any MSD unit with a “REGULATED” tab on the MSD View screen can become a Master unit.
Before using the Test Tool PN 89973 to validate compliance, it must be paired with the “Master”
unit. The designated Master unit should be programmed with the regulated parameter values
and their appropriate checkboxes selected in the REGULATED tab. Next, connect the Tech tool
to the Diagnostic Connector and follow the steps to replace the Master unit. At this point, the
unit is ready to check compliance when connected to any other MSD controller.
