        *1 (+) Terminal
        *2 (+) Connector
        *a

        Component without harness connected

        (Hybrid Battery Junction Block Assembly)

        Measure the resistance according to the value(s) in the table below.

        Standard Resistance
        Tester Connection Condition Specified Condition
        (+) connector - (+) terminal Auxiliary battery voltage is not applied between terminals 4 (SMRB) and 2 (GND) 10 kΩ or higher
        (+) connector - (+) terminal Auxiliary battery voltage is applied between terminals 4 (SMRB) and 2 (GND) Below 1 Ω

      2. Measure the resistance according to the value(s) in the table below.

        Standard Resistance
        Tester Connection Condition Specified Condition
        4 (SMRB) - 2 (GND) -40 to 176°F (-40 to 80°C) 18.4 to 36.3 Ω

        If the result is not as specified, replace the hybrid battery junction block assembly.

    2. Inspect SMRG

        *2 (-) Connector
        *a

        Component without harness connected

        (Hybrid Battery Junction Block Assembly)

        Measure the resistance according to the value(s) in the table below.

        Standard Resistance
        Tester Connection Condition Specified Condition
        (-) connector - (-) terminal Auxiliary battery voltage is not applied between terminals 1(SMRG) and 2(GND) 10 kΩ or higher
        (-) connector - (-) terminal Auxiliary battery voltage is applied between terminals 1(SMRG) and 2(GND) Below 1 Ω

      2. Measure the resistance according to the value(s) in the table below.

        Standard Resistance
        Tester Connection Condition Specified Condition
        1 (SMRG) - 2 (GND) -40 to 176°F (-40 to 80°C) 18.4 to 36.3 Ω

        If the result is not as specified, replace the hybrid battery junction block assembly.

    3. Inspect SMRP and precharge resistor

        *2 (-) Connector
        *a

        Component without harness connected

        (Hybrid Battery Junction Block Assembly)

        Measure the resistance according to the value(s) in the table below.

        Standard Resistance
        Tester Connection Condition Specified Condition
        (-) connector - (-) terminal Auxiliary battery voltage is not applied between terminals 3(SMRP) and 2(GND) 10 kΩ or higher
        (-) connector - (-) terminal Auxiliary battery voltage is applied between terminals 3(SMRP) and 2(GND) 28.5 to 31.5 Ω

      2. Measure the resistance according to the value(s) in the table below.

        Standard Resistance
        Tester Connection Condition Specified Condition
        3 (SMRP) - 2 (GND) -40 to 176°F (-40 to 80°C) 112 to 274 Ω

        If the result is not as specified, replace the hybrid battery junction block assembly.
