Repair Instruction: Initialization

Procedures necessary when ECU or other parts are replaced 

1. DESCRIPTION

   HINT:

   This registration section consists of two parts: Read VIN and Write VIN.

   1. Read VIN: Explains the VIN reading process in a flowchart. This process allows the VIN stored in the ECM to be read in order to confirm that the two VINs, provided with the vehicle and stored in the vehicle ECM, are the same.
   2. Write VIN: Explains the VIN writing process in a flowchart. This process allows the VIN to be input into the ECM. If the ECM is changed, or the ECM VIN and vehicle VIN do not match, the VIN can be registered, or overwritten in the ECM by following this procedure.
2. READ VIN
   1. Confirm the vehicle VIN.
   2. Connect the Techstream to the DLC3.
   3. Turn the engine switch on (IG).
   4. Turn the Techstream on.
   5. Enter the following menus: Powertrain / Engine and ECT / Utility / VIN / VIN Read.
3. WRITE VIN
   1. Confirm the vehicle VIN.
   2. Connect the Techstream to the DLC3.
   3. Turn the engine switch on (IG).
   4. Turn the Techstream on.
   5. Enter the following menus: Powertrain / Engine and ECT / Utility / VIN / VIN Write.

1. RESET MEMORY
   NOTE:

   • Perform the Reset Memory (AT initialization) when replacing the automatic transmission assembly, valve body assembly or any of the shift solenoid valves.
   • The Reset Memory can be performed only with the Techstream.

   HINT:

   The ECM memorizes the control conditions of the automatic transmission assembly and engine assembly. Therefore, when the automatic transmission assembly, valve body assembly or any of the shift solenoid valves has been replaced, it is necessary to reset the memory so that the ECM can memorize the new information.

   1. Connect the Techstream to the DLC3.
   2. Turn the engine switch on (IG).
   3. Turn the Techstream on.
   4. Enter the following menus: Powertrain / Engine and ECT / Utility / Reset Memory.
      NOTE: After performing the Reset Memory, be sure to perform the Road Test described earlier.

      HINT:

      The ECM learns through the Road Test.

1. BEFORE FILLING TRANSMISSION
   • This transmission requires Toyota Genuine ATF WS transmission fluid.
   • After servicing the transmission, you must refill the transmission with the correct amount of fluid.
   • Keep the vehicle level while adjusting the fluid level.
   • Proceed to the "Transmission Pan Fill" procedures if you replaced the entire transmission, transmission pan, drain plug, valve body and/or torque converter.
   • Proceed to the "Transmission Fill" procedures after removing the refill plug if you replaced the transmission hose and/or output shaft oil seal.

      2. Using a screwdriver, push the shaft of the thermostat.

         HINT:

         • Pushed amount: 5.5 to 7.0 mm (0.217 to 0.276 in.)
         • Push the shaft until the screwdriver contacts the inside step of the cap.
      3. With the shaft of the thermostat pressed, push a pin (diameter: 1.0 to 1.8 mm (0.0394 to 0.0709 in.)) into a hole on the side of the thermostat cap. Insert the pin until it passes through the hole on the other side of the thermostat cap to fix the shaft in place.

   3. Reinstall the refill plug to prevent the fluid from splashing.

      HINT:

      If you cannot add the listed amount of fluid, do the following:

      1. Install the refill plug.
      2. Allow the engine to idle with the air conditioning OFF.
      3. Move the shift lever through the entire gear range to circulate fluid.
      4. Wait for 30 seconds with the engine idling.
      5. Stop the engine.
      6. Remove the refill plug and add fluid.
      7. Reinstall the refill plug.
4. FLUID CIRCULATION
   1. Allow the engine to idle with the air conditioning OFF.
   2. Move the shift lever through the entire gear range to circulate fluid.
5. ADJUST FLUID TEMPERATURE
   NOTE: The fluid temperature can be confirmed by checking the indicator light in the meter or by using the Techstream. When using the Techstream, it is necessary to change to temperature detection mode in order to idle the vehicle appropriately.
   1. When using the Techstream:
      1. Turn the engine switch off.
      2. Connect the Techstream to the DLC3.
      3. Turn the engine switch on (IG).
      4. Enter the following menus: Powertrain / Engine and ECT / Active Test / Connect the TC and TE1.
      5. Enter the following menus: Powertrain / Engine and ECT / Data List / A/T Oil Temperature 1.
      6. Check the ATF temperature.
         NOTE:

         • If the fluid temperature is below 48°C (118°F), proceed to the next step. (Recommended ATF temperature: 43°C (109°F) or less)
         • If the fluid temperature is 48 C (118 F) or more, turn the engine switch off and wait until the fluid temperature drops below 43°C (109°F).
      7. According to the display on the Techstream, perform the Active Test "Connect the TC and TE1".

         HINT:

         Indicator lights of the combination meter blink to output DTCs when TC and TE1 are connected.

      8. Start the engine.
         NOTE: Check that electrical systems such as the air conditioning system, audio system and lighting system are off.
   2. When not using the Techstream:

      SST 09843-18040 

      1. Using SST, connect terminals 13 (TC) and 4 (CG) of the DLC3.
      2. Start the engine.
         NOTE: Check that electrical systems such as the air conditioning system, audio system and lighting system are off.

         HINT:

         Indicator lights of the meter blink to output DTCs when terminals TC and CG are connected.

   3. Slowly move the shift lever from P to S, then change the gears from 1st to 6th. Then return the shift lever to P.

      HINT:

      Slowly move the shift lever to circulate the fluid through each part of the transmission.

   4. Move the shift lever to D, and quickly move back and forth between N and D (once within 1.5 seconds) for at least 6 seconds. This will activate the fluid temperature detection mode.

      Standard condition: 

      Indicator light (D) remains illuminated for 2 seconds and then turns off. 

   5. When using the Techstream:
      1. Return the shift lever to P and press OFF on the Active Test display.
   6. When not using the Techstream:
      1. Return the shift lever to P and disconnect terminals 13 (TC) and 4 (CG).
   7. Allow the engine to idle until the fluid temperature reaches 43 to 48°C (109 to 118°F).
   8. The indicator (D) will come on again when the fluid temperature reaches 43°C (109°F) and will blink when it exceeds 48°C (118°F).

   1. Remove the overflow plug with the engine idling.
   2. Check that fluid comes out of the overflow tube. If fluid does not come out, proceed to the "Transmission Refill" procedures.

      If fluid comes out, wait until the overflow slows to a trickle and proceed to the "Complete" procedures.

7. TRANSMISSION REFILL
   1. Remove the overflow plug.
   2. Remove the refill plug and gasket.
   3. Add ATF into the refill hole until ATF flows from the overflow tube.

1. DESCRIPTION OF CODE REGISTRATION

   It is necessary to register the transmitter ID in the tire pressure warning ECU when replacing a tire pressure warning valve and transmitter and/or the tire pressure warning ECU:

   Prepare all transmitter ID data before starting registration.

   1. Before registration
      1. In case of tire pressure warning ECU replacement:
         • Read the registered transmitter IDs that are stored in the old ECU using the Techstream and note them down.
         • If reading the stored transmitter IDs is impossible due to malfunctions of components such as the tire pressure warning antenna and receiver, remove the tires from the wheels and check the IDs located on the tire pressure warning valve and transmitters.
      2. In case of tire pressure warning valve and transmitter replacement:
         • Take a note of the 7 digit number (transmitter ID) written on the tire pressure warning valve and transmitter.
