Fuel Gauge Relay Command

Display shows GASOLINE or ALT. FUEL. This display indicates the commanded state of the fuel gauge relay. The commanded state indicates which fuel system fuel level will be displayed by the instrument panel fuel gauge. The AF ECU will change the commanded state of the fuel gauge relay for about 10 seconds whenever the fuel gauge select switch is depressed.
