Outboard motor troubleshooting

Troubleshooting procedure

1.

Before troubleshooting the outboard motor, check that fresh fuel of the specified type has been
used.

2.

Check that all electrical connections are secure and free from corrosion, and that the battery is
fully charged.

3.

Check the trouble code using the YDIS first, and then check the electronic control system fol-
lowing the trouble code chart.

4.

When a trouble code is detected, check the data logger of the engine ECM record data graph as
well.

5.

If a trouble code is not detected, check the power unit according to “Troubleshooting the power
unit (trouble code not detected).”

6.

Before using the YDIS to check the power unit, check the engine ECM circuit. See “Checking
the engine ECM circuit” (5-28).

TIP:

• Make sure to check that the couplers and connectors are connected securely.
• When deleting the diagnosis record on the YDIS, make sure to check the time that the trouble

codes were detected.

• When checking the input voltage of a part, the coupler or connector must be disconnected. As a

result, the engine ECM determines that the part is disconnected and a trouble code is detected.
Therefore, make sure to delete the diagnosis record after checking the input voltage.

• Because the main relay comes on for approximately 10 seconds after the engine start switch is

turned to OFF, the power of the engine ECM cannot be turned off. Therefore, if the engine start
switch is turned to ON within 10 seconds after it was turned to OFF, the trouble codes cannot be
deleted.

Troubleshooting the power unit using the YDIS

1.

Use the trouble codes displayed by the YDIS to check each part according to the “Trouble code
and checking step” table.

2.

Delete the trouble codes after checking, repairing, or replacing a part and check that the trouble
codes are not detected again. If the same trouble codes are detected, the engine ECM may be
malfunctioning.

3.

Check the items listed in the table. If all of the items are in good condition, delete the trouble
codes, and then check the trouble codes again. If the same trouble codes are detected again,
the engine ECM is malfunctioning.
