FUEL MIXTURE CHECK (O
2
FEEDBACK)
Perform every 2 years.
#
Before performing a fuel mixture check (O2 feedback),
the outboard motor must be checked to be sure that
it is free of any trouble codes or operational prob-
lems.
To perform the O
2 feedback on 2003 year models, use the Suzuki
Diagnostic System (SDS) updated by the database version 4.10
(program version 4.00).
This section contains a set-up procedure on the outboard motor
side only. For the fuel mixture check (O
2
feedback) operation us-
ing the SDS, refer to the “SDS Operation Manual (program ver-
sion 4.00)”.
NOTE:
See the O
2
FEEDBACK SYSTEM section on the page 3-35 be-
fore starting the O
2
feedback operation.
