Tech Tips

Read Freeze Frame Data using the GTS. The ECM records vehicle and driving condition information as Freeze Frame Data the moment a DTC is stored. When troubleshooting, Freeze Frame Data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.

  4. PERFORM ACTIVE TEST USING GTS (ACTIVATE THE VALVEMATIC (ENG ON))


    1. Connect the GTS to the DLC3.

    2. Start the engine and warm it up until the engine coolant temperature stabilizes. (Engine coolant temperature 40°C or higher)

    3. Turn the engine switch off.

    4. Restart the engine.

      Tech Tips

      Do not operate the accelerator pedal.

    5. Turn the GTS on.

    6. Enter the following menus: Powertrain / Engine and ECT / Active Test / Activate the VALVEMATIC(ENG ON) / Data List / MAP, VALVEMATIC Target Angle, VALVEMATIC Current Angle, VALVEMATIC bef Warm Up.


      Powertrain > Engine and ECT > Active Test
      Active Test Display

      Data List Display
      MAP

      VALVEMATIC bef Warm Up

    7. Check the Data List "VALVEMATIC bef Warm Up" display is "ON".

      Tech Tips

      If "VALVEMATIC bef Warm Up" is not "ON".


      • Restart the engine. (Do not operate the accelerator pedal.)

      • Perform the Active Test "Activate the VALVEMATIC before Warm Up" to set "VALVEMATIC bef Warm Up" to "ON". (Do not operate the accelerator pedal.)

    8. Set the Active Test "Activate the VALVEMATIC(ENG ON)" to "High" and check that "VALVEMATIC Current Angle" follows "VALVEMATIC Target Angle" and the "MAP" value changes.

      Standard
      GTS Operation Result
      High

      VALVEMATIC Current Angle: 260 deg(CA)

      MAP: 25 to 40 kPa (188 to 300 mmHg)

    9. Set the Active Test "Activate the VALVEMATIC(ENG ON)" to "OFF", and check that "VALVEMATIC bef Warm Up" returns to "ON".

    10. Set the Active Test "Activate the VALVEMATIC(ENG ON)" to "Low" and check that "VALVEMATIC Current Angle" follows "VALVEMATIC Target Angle" and the "MAP" value changes.

      Standard
      GTS Operation Result
      Low

      VALVEMATIC Current Angle: 106 deg(CA)

      MAP: 35 to 65 kPa (263 to 488 mmHg)
      OK
      When performing the Active Test, "VALVEMATIC Current Angle" follows "VALVEMATIC Target Angle" and the "MAP" value changes.

      Tech Tips


      • After the accelerator pedal is depressed and the Active Test operates once to "Low", "VALVEMATIC bef Warm Up" does not return to "ON". Therefore, in order to repeat the inspection, it is necessary to either perform the Active Test "Activate the VALVEMATIC before Warm Up" to set the VALVEMATIC system to the operating position that occurs before the engine is warmed up, or restart the engine.

      • When the vehicle is driven while there is a malfunction in the VALVEMATIC system and the valve lift amount is fixed at the minimum, the vehicle speed cannot exceed 30 to 60 km/h (19 to 37 mph).

      • If the intake valve advance angle is within the VALVEMATIC operation prohibition range depending on the operating state of the VVT system, the Active Test "Activate the VALVEMATIC(ENG ON)" is prohibited. If the advance angle cannot be detected due to a malfunction in the VVT system, the Active Test "Activate the VALVEMATIC(ENG ON)" is prohibited.
