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

      Standard Resistance
      Tester Connection Condition Specified Condition
      K15-6 (IOUT) - D80-7 (ISIF) Always Below 1 Ω
      K15-6 (IOUT) or D80-7 (ISIF) - Body ground Always 10 kΩ or higher
      K15-11 (GND) - Body ground Always Below 1 Ω

    NG
