1. INSPECT HYBRID BATTERY JUNCTION BLOCK ASSEMBLY


  1. Inspect SMRB



      A215628E01

    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
