1.COMBINATION METER INPUT SIGNAL
1. Select METER/M&A on CONSULT.
2. Using FUEL METER of DATA MONITOR, compare the value of DATA MONITOR with fuel gauge pointer
of combination meter.
Does the data monitor value approxim ately match the fuel gauge indication?
YES >> Inspection End.
NO >> Replace combination meter. Refer to MWI-82, "Removal and Installation"
.
