        (Hybrid Battery Junction Block Assembly)

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

        Standard Resistance
        Tester Connection Condition Specified Condition
        A-1 (+) - Q2-1 (CBI) Auxiliary battery voltage is not applied between terminals O9-1 (SMRB) and O9-2 (GND) 10 kΩ or higher
        A-1 (+) - Q2-1 (CBI) Auxiliary battery voltage is applied between terminals O9-1 (SMRB) and O9-2 (GND) Below 1 Ω
      2. Measure the resistance according to the value(s) in the table below.

        Standard Resistance
        Tester Connection Condition Specified Condition
        O9-1 (SMRB) - O9-2 (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.

        Tester Connection Condition Specified Condition
        q1-1 (-) - Q3- 1 (CEI) Auxiliary battery voltage is not applied between terminals O9-3 (SMRG) and O9-2 (GND) 10 kΩ or higher
        q1-1(-) - Q3- 1 (CEI) Auxiliary battery voltage is applied between terminals O9-3 (SMRG) and O9-2 (GND) Below 1 Ω
      2. Measure the resistance according to the value(s) in the table below.

        Standard Resistance
        Tester Connection Condition Specified Condition
        O9-3 (SMRG) - O9-2 (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.

        (Hybrid Battery Junction Block Assembly)

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

        Standard Resistance
        Tester Connection Condition Specified Condition
        q1-1 (-) - Q3- 1 (CEI) Auxiliary battery voltage is not applied between terminals O9-4 (SMRP) and O9-2 (GND) 10 kΩ or higher
        q1-1(-) - Q3- 1(CEI) Auxiliary battery voltage is applied between terminals O9-4 (SMRP) and O9-2 (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
        O9-4 (SMRP) and O9-2 (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.
