HV RELAY ASSEMBLY INSPECTION

  1. INSPECT HYBRID BATTERY JUNCTION BLOCK ASSEMBLY

    1. Inspect SMRB.

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

        A011VNUE14
        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

        (Hybrid Battery Junction Block Assembly)

      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.

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

        A011VNUE15
        Standard Resistance
        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.

    3. Inspect SMRP.

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

        A011VNUE13
        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
