Diagnosing the electronic control
system
1. Connect the special tools to the outboard
motor as shown.
NOTE:
When performing this diagnosis, all of the
electrical wires must be properly connected.
2. Start the engine and let it idle.
3. Check the flash pattern of the diagnostic
indicator to determine if there are any
malfunctions.

(no defective part or irregular process-
ing is found)
• Single flash is given every 4.95 sec-
onds.
a
: Light on, 0.33 second
b
: Light off, 4.95 seconds
• Trouble code indication
Example: The illustration indicates
code number 23.
a
: Light on, 0.33 second
b
: Light off, 4.95 seconds
b
: Light off, 0.33 second
d

4. If a flash pattern listed in the diagnosis
code chart is displayed, check the mal-
functioning part according to the flash
pattern.
NOTE:
When more than one problem is detected,
the light of the diagnostic tester flashes in the
pattern of the lowest numbered problem.
After that problem is corrected, the light
flashes in the pattern of the next lowest num-
bered problem. This continues until all of the
problems are detected and corrected.
