        STANDARD REFERENCE

        Tester Connection Specified Condition
        3-4 Below 1 Ω
        3-5 10 kΩ or higher
        3-4 10 kΩ or higher (Apply battery voltage to terminals 1 and 2)
        3-5 Below 1 Ω (Apply battery voltage to terminals 1 and 2)

        If the result is not as specified, replace the fuel pump relay.
