The ACom PRO Diagnostic Software can be started from
the desktop shortcut. To begin, the technician should
select “Connect” from the main toolbar, then “Heavy Duty”
connection type. The “Heavy Duty” button connects to the
vehicle BUS using all vehicle protocols. This process could
take approximately two (2) minutes. After the connection is
complete, the roll call will show the ECU and its active and
inactive DTCs. The connection depends on a compatible
RP1210C adapter. For assistance with the ACom PRO
