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

      Standard resistance 

      RESISTANCE SPECIFIED CONDITION

      Tester Connection Specified Condition
      S1-8 (TRC+) - E6-25 (VSC+) Below 1 Ω
      S1-22 (TRC-) - E6-31 (VSC-) Below 1 Ω
      S1-9 (ENG+) - E6-24 (ENG+) Below 1 Ω
      S1-23 (ENG-) - E6-30 (ENG-) Below 1 Ω
    4. Measure the resistance according to the value(s) in the table below.

      Standard resistance 

      RESISTANCE SPECIFIED CONDITION

      Tester Connection Specified Condition
      S1-8 (TRC+) - Body ground 10 kΩ or higher
      S1-22 (TRC-) - Body ground 10 kΩ or higher
