Figure 28 2006 - Up 25hp & 30hp EFI 4-Stroke ECM
Mercury’s 2006 and newer 25hp and 30hp EFI 4-cycle engines with Tohatsu
powerheads are supported by the scan tool. ese engines are equipped with a
2-connector Kokusan Denki electronic control module as shown in Figure 28.
Engines equipped with this ECM type do not have battery power available
from the engine diagnostic connector. e engine must be started to power up
the ECM and subsequently obtain live data. To connect to this system use the
following steps:
18-pin Adapter
Rinda Tech P/N 94039
1) Locate the engine’s 18-pin diagnostic link connector (DLC). is connector is
built into the ECM module as shown in Figure 28.
2) Plug adapter #94039 into the engine’s DLC. Aerward attach the adapter’s
Red and Black power wires to a suitable 12 vdc power source. Attach the Red
clip to +12vdc and the Black clip to the power source ground. ese connec-
tions are necessary in order to provide power to the scan tool.
