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

      Component without harness connected

      (Hybrid Battery Junction Block Assembly)

      Inspect SMRB


      1. 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) 20.6 to 40.8 Ω

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