Inspection [08/2013 - ]

WARNING: This page is about a different car, the 2014 Lexus ES 300h. However, it is still accessible from the selected car via links, so may be relevant.
  1. INSPECT HYBRID BATTERY JUNCTION BLOCK ASSEMBLY 
    1. Inspect SMRB
      1. Measure the resistance according to the value(s) in the table below.

        Standard Resistance

        Tester Connection Condition Specified Condition
        A-1 (+) - S2-1 (CBI) Auxiliary battery voltage is not applied between terminals Q6-1 (SMRB) and Q6-2 (GND) 10 kΩ or higher
        A-1 (+) - S2-1 (CBI) Auxiliary battery voltage is applied between terminals Q6-1 (SMRB) and Q6-2 (GND) Below 1 Ω
