СИСТЕМА ПРЕДПУСКОВОГО ПОДОГРЕВА ПРОВЕРКА БЕЗ СНЯТИЯ С АВТОМОБИЛЯ

Note

Turn the ignition switch off for 60 seconds before performing the following inspections.


  1. INSPECT ILLUMINATION DURATION OF GLOW INDICATOR LIGHT


    1. Turn the ignition switch to ON and measure the duration of time that the light remains illuminated.

      A01ITO7E01
      Light illumination duration
      Refer to the graph
      Standard Light Illumination Time
      Engine Coolant Temperature Specified Condition
      -20°C (-4°F) 10 to 12 seconds
      -15°C (5°F) 6.0 to 8.0 seconds
      0°C (32°F) 3.0 to 5.0 seconds
      35°C (95°F) 0.45 to 1.0 seconds

      If the result is not as specified, check the ECM, engine coolant temperature sensor, glow plugs and glow plug relay.

  2. INSPECT PRE-HEATING


    1. Turn the ignition switch to ON and measure the length of time that battery voltage is applied to the glow plugs.

      A01IS5VE01
      Standard Pre-heating Time
      Engine Coolant Temperature Specified Condition
      40°C (104°F) or higher 1 second
      40°C (104°F) or less

      Refer to the graph*1

      (Maximum 15 seconds)

      *1: Pre-heating time changes depending on battery voltage.

      If the result is not as specified, check the ECM, engine coolant temperature sensor, glow plugs and glow plug relay.

  3. INSPECT AFTER GLOW TIME


    1. A01ISATE04

      *1

      Front view of wire harness connector

      (to Glow Plug Relay)

      Remove the glow plug relay.

    2. After the engine starts, measure the length of time that battery voltage remains present.

      A01IQ21E02
      Standard After Glow Time
      Tester Connection Condition Specified Condition
      A43-2 - Body ground After engine starts Refer to the graph above

      If the result is not as specified, check the ECM, engine coolant temperature sensor, glow plugs and glow plug relay.
