INSPECTION PROCEDURE

NOTICE:
  1. Inspect the fuses of circuits related to this system before performing the following inspection procedure.
  2. After replacing the ECM, the new ECM needs registration (HILUX_TGN26 RM0000012XK058X.html) and initialization (HILUX_TGN26 RM000000TIN056X.html).
  3. After replacing the fuel supply pump assembly, the ECM needs initialization (HILUX_TGN26 RM000000TIN056X.html).
  4. After replacing an injector assembly, the ECM needs registration (HILUX_TGN26 RM0000012XK058X.html).
HINT:
Read freeze frame data using the intelligent tester. Freeze frame data records the engine condition when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, and other data from the time the malfunction occurred.
1.CHECK OTHER DTC OUTPUT (IN ADDITION TO DTC P011C)

  1. Connect the intelligent tester to the DLC3.

  1. Turn the ignition switch to ON and turn the tester on.

  1. Enter the following menus: Powertrain / Engine and ECT / DTC.

  1. Read the DTCs.

2.READ VALUE USING INTELLIGENT TESTER (ENGINE COOLANT TEMPERATURE)

  1. Allow the engine to soak for 1 to 2 hours.

    HINT:
    1. It is not necessary to allow the engine to soak if the engine is cold.
    2. The engine cools faster if the hood is opened.

  1. Connect the intelligent tester to the DLC3.

  1. Turn the ignition switch to ON and turn the tester on.

  1. Enter the following menus: Powertrain / Engine and ECT / Data List / Coolant temp.

  1. Read the value.

    OK:
    The difference between the displayed value and outside air temperature is below 5°C (9°F).
    NOTICE:
    If the difference between "Coolant Temp" and the outside air temperature is 5°C (9°F) or higher, the heat from the engine affects the intake air temperature sensor, causing an incorrect value to be displayed. In this case, allow the engine to soak again.

3.READ VALUE USING INTELLIGENT TESTER (INTAKE AIR TEMPERATURE)

  1. Connect the intelligent tester to the DLC3.

  1. Turn the ignition switch to ON and turn the tester on.

  1. Enter the following menus: Powertrain / Engine and ECT / Data List / Intake Air.

  1. Read the value.

    OK:
    The difference between the displayed value and outside air temperature is below 15°C (27°F).

Go to step 6
OK


4.READ VALUE USING INTELLIGENT TESTER (INTAKE AIR TEMPERATURE (TURBO))

  1. Connect the intelligent tester to the DLC3.

  1. Turn the ignition switch to ON and turn the tester on.

  1. Enter the following menus: Powertrain / Engine and ECT / Data List / Intake Air Temp (Turbo).

  1. Read the value.

    OK:
    The difference between the displayed value and outside air temperature is below 15°C (27°F).
