      - -
    2. Measure the voltage according to the value(s) in the table below.

      Standard

      Tester Connection Input/Output Item Condition Specified Condition
      1 (IG) - Body ground Input Voltage Ignition switch ON 11 to 14 V
    3. Measure the resistance according to the value(s) in the table below.

      Standard

      Tester Connection Input/Output Item Condition Specified Condition
      4 (GND) - Body ground - Resistance Always Below 1 Ω

      If the result is not as specified, repair or replace the harness or connector.

    4. Reconnect the M79 voltage inverter assembly connector.

    5. Measure the voltage according to the value(s) in the table below.

      Standard

      Tester Connection Input/Output Item Condition Specified Condition
      3 (AC1) - 7 (AC2)
      *1
      Output Voltage Inverter operating with ignition switch ON 121 to 165 V
      *2
      7 (AC2) - 3 (AC1)
      *1
      Output Voltage Inverter operating with ignition switch ON 121 to 165 V
      *2

      HINT: 

      • *1: When measuring with the tester, set the tester to the AC voltage range as the generated voltage is AC.
      • *2: Since the AC voltage cannot be precisely measured with the tester, a wide range has been listed for the specified condition.

      If the result is not as specified, replace the voltage inverter assembly.
