  2. ADJUST FLUID TEMPERATURE (when Using the GTS)

    Tech Tips

    The actual ATF temperature can be checked on the Data List using the GTS.


    1. Connect the GTS to the DLC3 with the engine switch off.

    2. Turn the engine switch on (IG) and turn the GTS on.

      Note

      To reduce load, make sure that all electrical systems, such as the air conditioning, lighting system, electric fan and audio system, are off.

    3. Enter the following menus: Powertrain / Engine and ECT / Active Test / Connect the TC and TE1

    4. Select the Data List menu: A/T Oil Temperature 1

    5. Select the Active Test menu: Connect the TC and TE1 / ON

    6. Check the ATF temperature.

      Note


      • If the fluid temperature is below 45°C (113°F), proceed to the next step. [Recommended ATF temperature: 35°C (95°F) or less]

      • If the fluid temperature is 45°C (113°F) or more, turn the engine switch off and wait until the fluid temperature drops below 45°C (113°F).

    7. Depress and hold the brake pedal.

    8. Start the engine.

    9. Slowly move the shift lever from P to D, then back to P (keep the shift lever in each position for approximately 3 seconds).

    10. A01G9NV

      While observing the D shift indicator on the combination meter, move the shift lever back and forth between N and D at an interval of less than 1.5 seconds for 6 seconds or more.

      Note

      Do not pause for more than 1.5 seconds.

      Tech Tips

      Performing this operation will cause the vehicle to enter fluid temperature detection mode.

    11. Check that the D shift indicator comes on for 2 seconds.

      Tech Tips


      • When fluid temperature detection mode is activated, the D shift indicator on the combination meter comes on for 2 seconds.

      • If the D shift indicator does not come on for 2 seconds, return to the first step and perform the procedure again.

    12. Move the shift lever from N to P.

    13. Release the brake pedal.

    14. Select the Active Test menu: Connect the TC and TE1 / OFF

      Note

      Be sure that terminals TC and TE1 are off. If the terminals are on, the fluid level cannot be precisely adjusted due to fluctuations in engine speed.

      Tech Tips


      • Disconnecting terminals TC and TE1 activates engine idle speed control mode.

      • In engine idle speed control mode, engine idle speed control starts when the fluid temperature becomes 35°C (95°F) or more and the engine speed is maintained at approximately 800 rpm.

      • Even after terminals TC and TE1 are disconnected, fluid temperature detection mode is active until the engine switch is turned off.

      *3 Hexagon Socket Wrench

      Using a 6 mm hexagon socket wrench, remove the overflow plug and gasket.

      CAUTION:

      Be careful as the fluid coming out of the overflow plug hole is hot.

    3. Check the amount of fluid that comes out of the overflow plug hole.

      Note

      If only a small amount of fluid (approximately 1 cc) comes out of the overflow plug hole, then only fluid remaining in the No. 1 transmission oil filler tube has come out. This condition is not considered as overflow, so it is necessary to add fluid.

    4. If the fluid overflows


      1. A01G5HC

        Remove the refill plug and gasket.

      2. A01G5Q2
