Battery Current Sensor: Inspection

  1. INSPECT BATTERY CURRENT SENSOR 
    1. Inspect the resistance.
      1. Measure the resistance between terminals 1 (VIB) and 2 (GIB).

        Standard resistance 

        TERMINALS RESISTANCE SPECIFICATION

        Tester Connection Resistance
        Positive probe to terminal 1 (VIB)
        Negative probe to terminal 2 (GIB)
        3.5 to 4.5 kΩ
        Positive probe to terminal 2 (GIB)
        Negative probe to terminal 1 (VIB)
        5 to 7 kΩ

        If the results are not as specified, replace the battery current sensor.

      2. Measure the resistance between terminals 1 (VIB) and 3 (IB).

        Standard resistance 

        TERMINALS RESISTANCE SPECIFICATION

        Tester Connection Resistance
        Positive probe to terminal 1 (VIB)
        Negative probe to terminal 3 (IB)
        3.5 to 4.5 kΩ
        Positive probe to terminal 1 (VIB)
        Negative probe to terminal 3 (IB)
        5 to 7 kΩ

        If the results are not as specified, replace the battery current sensor.

      3. Measure the resistance between terminals 2 (GIB) and 3 (IB).

        Standard resistance: 

        0.2 kΩ or less 

        NOTE: Even if the probes are changed around, the resistance will not vary.

        If the result is not as specified, replace the battery current sensor.
