Diagnostic Circuit Check
The Diagnostic Circuit Check is an organized ap-
proach to identifying a problem created by an elec-
tronic engine control system malfunction. It must be
the starting point for any driveability complaint diag-
nosis because it directs the service technician to the
next logical step in diagnosing the complaint.
NOTE: A scan tool that displays faulty data should
not be used, and the problem should be reported to
the manufacturer. The use of a faulty scan tool can
result in misdiagnosis and unnecessary parts re-
placement.
The scan tool data listed in the table may be used for
comparison. After completing the diagnostic circuit
check and finding the on-board diagnostics function-
ing properly and no trouble codes displayed. The
“Typical Data Values” are an average of display val-
ues recorded from normally operating vessels and
are intended to represent what a normally functioning
system would typically display.
Only the parameters listed below are used in this
manual for diagnosing. If a scan reads other parame-
ters, the values are not recommended for use in diag-
nosing. If all values are within the range illustrated,
refer to “Troubleshooting.”
