СИСТЕМА ПРЕДПУСКОВОГО ПОДОГРЕВА ПРОВЕРКА БЕЗ СНЯТИЯ С АВТОМОБИЛЯ

CAUTION / NOTICE / HINT

Note

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

PROCEDURE


  1. INSPECT LIGHTING TIME OF GLOW INDICATOR LIGHT


    1. A01XFIEE05
      Text in Illustration
      *a Glow Indicator Lighting Time
      *b Engine Coolant Temperature

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

      Lighting time
      Refer to the graph

      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. A01XFWTE06
      Text in Illustration
      *a Pre-heating Time
      *b Battery Voltage

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

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

      Refer to the graph

      (15 seconds at longest)

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

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

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

      Pre-heating Time
      Engine Coolant Temperature Specified Condition
      40°C (104°F) or higher 1 second
      Below 40°C (104°F) Refer to the graph (15 seconds at longest)

  3. INSPECT AFTER GLOW TIME


    1. A01XDGXE02
      Text in Illustration
      *a After Glow Time
      *b Engine Coolant Temperature

      After starting the engine, measure the time that battery voltage is applied to the terminal SREL of the ECM.

      After glow time
      Refer to the graph

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