Connecting to the PCM-555 / ECM-555 EFI Systems
e TechMate Pro scan tool provides an extensive set of diagnostic and support
functions for troubleshooting engines equipped with the PCM SmartCra engine
control system.
Two types of diagnostic connectors were used on outboard engines equipped
with these EFI systems. As a general rule most outboard engines 2005 and ear-
lier that utilize Smartcra PCMs (PCM-555 or ECM-555) are tted with a 2-pin
diagnostic connector. Starting in 2006 Mercury began using a 4-pin diagnostic
connector on most of their Smartcra PCM equipped engines. One exception
to this is on Verado engines. All Verado engines 2005 and newer use the 4-pin
style connector.
To connect the TechMate Pro scan tool follow the steps below. e two possible
types of diagnostic adapters required for these systems are shown at the bottom
of this page.
