OBD-M Compliant ECMs
Page 32
e TechMate Pro scan tool supports marine engines that comply with the 2008
California / EPA mandated OBD-M diagnostic specication. e scan tool dis-
plays both live data and fault codes on these systems.
OBD-M live data
e live data displayed by the scan tool is dependent upon the engine manufac-
turer’s engine control system conguration. e OBD-M specication denes a
set of common engine parameters that are available to service technicians using a
scan tool if the those parameters apply to the engine being diagnosed.
Connecting to an OBD-M system
1) Locate the engine’s 6 pin OBD-M diagnostic connector. e location of this
connector is specied in the engine manufacturer’s service manual. Please
note that the connector may have a protective cap attached to it.
2) With the engine’s ignition switch in the OFF position, plug the scan tool’s
communication cable into the diagnostic connector. Scan tool adapter #94029
(CAN Network Adapter) is required for this application as shown below.

3) Once the tool is connected turn the ignition switch ON, start the engine or
simply leave the ignition switch ON and proceed.
4) Aer the scan tool displays its initial opening messages use the ▲ and ▼ keys
to select the “Sterndrive / Inboards” menu item then press the YES key.
5) Aer selecting the “Sterndrive / Inboards” function the scan tool will attempt
to communicate with the engine’s ECM and automatically identify it. To
obtain general diagnostic data select the “ECM Data” function. is menu
choice causes the scanner to begin reading information from the ECM mod-
ule. Follow the prompts on the scan tool display screen.
OBD-M Fault Codes
To obtain engine fault codes select the “ECM Faults” menu item. A display of
active, pending and previously active faults will appear. Choose the category of
interest and the scan tool will retrieve and display the fault information.
