        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
        (+) - (CBI) Battery voltage is not applied between terminals 1 (SMRB) and 2 (GND) 10 kΩ or higher
        Battery voltage is applied between terminals 1 (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
        1 (SMRB) - 2 (GND) -40 to 80°C (-40 to 176°F) 25.0 to 59.0 Ω

        If the result is not as specified, replace the hybrid battery junction block assembly or electric vehicle fuse.

    2. Inspect SMRG.

        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
        (CEI) - (-) Battery voltage is not applied between terminals 3 (SMRG) and 2 (GND) 10 kΩ or higher
        Battery voltage is applied between terminals 3 (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
        3 (SMRG) - 2 (GND) -40 to 80°C (-40 to 176°F) 25.0 to 59.0 Ω

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

    3. Inspect SMRP.

        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
        (CEI) - (-) Battery voltage is not applied between terminals 4 (SMRP) and 2 (GND) 10 kΩ or higher
        Battery voltage is applied between terminals 4 (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
        4 (SMRP) - 2 (GND) -40 to 80°C (-40 to 176°F) 112 to 274 Ω

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