HV RELAY ASSEMBLY INSPECTION

PROCEDURE


  1. INSPECT HYBRID BATTERY JUNCTION BLOCK ASSEMBLY


    1. Inspect SMRB.


      1. A00YOXCC01
        *a

        Component without harness connected

        (Hybrid Battery Junction Block Assembly)

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

        Standard Resistance
        Tester Connection Condition Specified Condition
        W2-1 (CBI) - A-1(+) Auxiliary battery voltage is not applied between terminals L49- 1 (SMRB) and L49-2 (GND) 10 kΩ or higher
        Auxiliary battery voltage is applied between terminals L49- 1 (SMRB) and L49-2 (GND) Below 1 Ω

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

        Standard Resistance
        Tester Connection Condition Specified Condition
        L49-1 (SMRB) - L49-2 (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.

    2. Inspect SMRG.


      1. A00YPN2C01
        *a

        Component without harness connected

        (Hybrid Battery Junction Block Assembly)

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

        Standard Resistance
        Tester Connection Condition Specified Condition
        W3-1 (CEI) - t1-1(-) Auxiliary battery voltage is not applied between terminals L49- 3 (SMRG) and L49-2 (GND) 10 kΩ or higher
        Auxiliary battery voltage is applied between terminals L49- 3 (SMRG) and L49-2 (GND) Below 1 Ω

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

        Standard Resistance
        Tester Connection Condition Specified Condition
        L49-3 (SMRG) - L49-2 (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. A00YPN2C03
        *a

        Component without harness connected

        (Hybrid Battery Junction Block Assembly)

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

        Standard Resistance
        Tester Connection Condition Specified Condition
        W3-1 (CEI) - t1-1(-) Auxiliary battery voltage is not applied between terminals L49-4 (SMRP) and L49-2 (GND) 10 kΩ or higher
        Auxiliary battery voltage is applied between terminals L49-4 (SMRP) and L49-2 (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
        L49-4 (SMRP) - L49-2 (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.
