On-Vehicle Inspection

  1. ST relay check
    1. Check the resistance between relay connector terminals.

      Resistance

      Inspection terminals Inspection conditions Standard value
      1 - 2 20°C 93.8 to 136.4Ω
      3 - 5 When the battery voltage is not applied to the terminal 1 and terminal 2: 10 k Ωor more
      When the battery voltage is applied to the terminal 1 and terminal 2: Less than 1 Ω
