Connecting to PCM-09 Systems (continued)
Some applications have a free hanging 10-pin CAN connector located on the
engine’s electrical harness as shown in Figure 25. To connect to this type of
CAN port remove the CAN connector’s protective cap (or terminator) and
attach the scan tool.

Engine / ECM Detection
Aer selecting the “Sterndrives / Inboards” system type the scan tool will rst
determine if more than one engine is available for diagnosis. Multi-engine
vessels oen have their engines inter-connected via the vessel’s CAN bus and can
therefore be diagnosed from a single CAN port. For all available engines to be
detected by the TechMate Pro scan tool they must have their ignition switches
turned ON or be running.
