    Note

    Turn the ignition switch off for 60 seconds before performing this inspection.


    1. Turn the ignition switch to the ON position, and measure the lighting time.

      Lighting time
      Refer to the graph

  2. INSPECT PRE-HEATING

    A01DYYKE03

    Note

    Turn the ignition switch off for 60 seconds before performing this inspection.


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

      Standard pre-heating time
      Engine Coolant Temperature Condition Specified Condition
      40°C (104°F) or more 1 sec.
      40°C (104°F) or less Refer to the graph (15 sec. at the longest)

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

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

      Standard pre-heating time
      Engine Coolant Temperature Condition Specified Condition
      40°C (104°F) or more 1 sec.
      40°C (104°F) or less Refer to the graph (15 sec. at the longest)

  3. INSPECT AFTER GLOW TIME

    Note

    Turn the ignition switch off for 60 seconds before performing this inspection.

    A01E2LYE01

    1. After the engine starts, measure how long it takes for battery voltage to be applied to terminals E20-2 (SREL) and E23-14 (E1) of the ECM.

      Standard time
      Tester Connection Specified Condition
      E20-2 (SREL) - E23-14 (E1) See graph

      If the result is not as specified, inspect the ECM, ECT sensor, glow plug and GLOW relay.
