Unit Inspection

  1. Inspect the battery current sensor assembly.
    1. Resistance check (Battery current sensor assembly).
      1. Measure the resistance between the terminals.
      RESISTANCE

      Inspection terminals Tester positive - Tester negative Inspection conditions Standard value
      1(VIN) - 3(GND) Always 3 - 10 kΩ
      1(VIN) - 4(VOUT) Always 0.5 kΩ or less
      3(GND) - 4(VOUT) Always 3 - 10 kΩ

    2. Resistance check (Battery thermometer sensor).
      1. Measure the resistance between the terminals.
      RESISTANCE

      Inspection terminals Inspection conditions Standard value
      2(TEMP) - 3(GND) 20 - 30°C {68 - 86°F} 1.5 - 2.6 kΩ
