DIAGNOSTIC SOFTWARE FUNCTIONS
Overheat
This test is used to check the “ENG TEMP” or
“HOT” circuit of the Engine Monitoring system.
Oil Fault
This test is used to check the “NO OIL” circuit of
the Engine Monitoring system.
Check Engine
This test is used to check the “CHECK ENGINE”
circuit of the Engine Monitoring system.
Tachometer
This test is used to check operation of the tachom-
eter circuit.
Dynamic Tests
Dynamic tests are performed with the outboard
running.
Ignition Test
This test momentarily disables the ignition and
fuel injection circuits to one cylinder. By dropping
one cylinder, RPM and running quality changes
can be observed. Refer to DYNAMIC TESTS on
p. 80.
Fuel Test
This test momentarily disables one fuel injector
circuit. By dropping one cylinder, RPM and run-
ning quality changes can be observed. Refer to
DYNAMIC TESTS on p. 80.
Prime Oil
This test is used to cycle the oil injection pump for
priming the oiling system. Perform this test with
outboard running to activate oil injection pump.
Oil Control Settings
Set Oil Type
The TC-W3 oil type setting is the standard setting
for all outboards. Set TC-W3 for:
• Operation with all TC-W3 outboard oils includ-
ing XD30, XD50, or XD100
• Applications requiring maximum lubrication
• Extreme applications (racing or harsh condi-
tions).
The XD100 setting provides an option to run the
outboard at a reduced oil injection rate. This set-
ting REQUIRES the use of Evinrude XD100 out-
board lubricant and is not recommended for all
applications.
Use the XD100 setting for:
• Conventional use (runabouts, cruisers)
• Moderate applications.

A CAUTION
Running an Evinrude E-TEC outboard on
other grades of oil while set to the XD100
oil ratio will result in increased engine
wear and shortened outboard life.
