Inspection [11/2021 - ]: Procedure

WARNING: This page is about a different car, the 2025 Lexus NX 350h, 2024 Lexus NX 350h, 2023 Lexus NX 350h, and 2022 Lexus NX 350h. However, it is still accessible from the selected car via links, so may be relevant.
  1. INSPECT HV BATTERY JUNCTION BLOCK ASSEMBLY 
    1. Inspect SMRB:
      1. Measure the resistance according to the value(s) in the table below.

        *a Component without harness connected
        (HV Battery Junction Block Assembly)        		 - -

        Standard Resistance

        Tester Connection Condition Specified Condition
        z2-1 (+) - S3-1 (CBI) Auxiliary battery voltage not applied between terminals G15-1 (SMRB) and G15-3 (GND) 10 kΩ or higher
        Auxiliary battery voltage applied between terminals G15-1 (SMRB) and G15-3 (GND) Below 1 Ω
      2. Measure the resistance according to the value(s) in the table below.

        Standard Resistance

        Tester Connection Condition Specified Condition
        G15-1 (SMRB) - G15-3 (GND) -40 to 80°C (-40 to 176°F) 19.0 to 59.0 Ω

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

    2. Inspect SMRG:
      1. Measure the resistance according to the value(s) in the table below.

        *a Component without harness connected
        (HV Battery Junction Block Assembly)        		 - -

        Standard Resistance

        Tester Connection Condition Specified Condition
        z12-1 (-) - S5-1 (CEI) Auxiliary battery voltage not applied between terminals G15-4 (SMRG) and G15-3 (GND) 10 kΩ or higher
        Auxiliary battery voltage applied between terminals G15-4 (SMRG) and G15-3 (GND) Below 1 Ω
      2. Measure the resistance according to the value(s) in the table below.

        Standard Resistance

        Tester Connection Condition Specified Condition
        G15-4 (SMRG) - G15-3 (GND) -40 to 80°C (-40 to 176°F) 19.0 to 59.0 Ω

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

    3. Inspect SMRP:
      1. Measure the resistance according to the value(s) in the table below.
        GTY1059608Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
        *a Component without harness connected
        (HV Battery Junction Block Assembly)        		 - -

        Standard Resistance

        Tester Connection Condition Specified Condition
        z12-1 (-) - S5-1 (CEI) Auxiliary battery voltage not applied between terminals G15-2 (SMRP) and G15-3 (GND) 10 kΩ or higher
        Auxiliary battery voltage applied between terminals G15-2 (SMRP) and G15-3 (GND) 24.3 to 29.7 Ω
      2. Measure the resistance according to the value(s) in the table below.

        Standard Resistance

        Tester Connection Condition Specified Condition
        G15-2 (SMRP) - G15-3 (GND) -40 to 80°C (-40 to 176°F) 140 to 290 Ω

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