СИСТЕМА ПРЕДПУСКОВОГО ПОДОГРЕВА ПРОВЕРКА БЕЗ СНЯТИЯ С АВТОМОБИЛЯ

Note

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


  1. INSPECT LIGHTING DURATION OF GLOW INDICATOR LIGHT


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

      A011AEZE01
      Light illumination duration
      Refer to the graph and the table *1
      *1: Lighting duration depending on atmospheric pressure.

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

      Light Illumination Duration

      Engine Coolant Temperature

      °C (°F)

      Light Illumination Time

      (sec.)
      -20 (-4) 15
      0 (32) 10
      10 (50) 8
      20 (68) 5
      40 (104) 3

  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.

      A011AZBE02
      Pre-heating time
      Refer to the graph *1
      *1: Pre-heating time changes depending on battery voltage and engine coolant temperature.

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

    2. Turn the ignition switch to the START position and check that the battery voltage is applied to the glow plugs.

    3. While cranking the engine, measure the length of time that battery voltage is applied to the glow plugs.

      Pre-heating time
      Refer to the graph *1
      *1: Pre-heating time changes depending on battery voltage and engine coolant temperature.

      Note

      Do not start the engine.

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

  3. INSPECT AFTER GLOW TIME

      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.

      A0117M5E01
      After Glow Time
      Tester Connection Condition Specified Condition
      B11-2 - Body ground - Refer to the graph above*1

      *1: After glow time depending on atmospheric pressure and engine coolant temperature.

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