Inspection Procedure

WARNING: This page is about a different car, the 2008 Toyota RAV4. However, it is still accessible from the selected car via links, so may be relevant.

HINT:

Performing Techstream's Active Test allows relay, VSV, actuator and other items to be operated without removing any parts. Performing the Active Test early in troubleshooting is one way to save time.

The Data List can be displayed during the Active Test.

  1. Warm up the engine.
  2. Turn the ignition switch OFF.
  3. Connect Techstream to the DLC3.
  4. Turn the ignition switch ON and turn the tester ON.
  5. Enter the following menus: Powertrain / Engine and ECT / Active Test.
  6. Follow the instructions on the tester and perform the Active Test.

HINT:

While driving, the shift position can be forcibly changed with the tester.

Comparing the shift position commanded by the Active Test with the actual shift position enables you to confirm the problem (See FAIL-SAFE CHART  ).

HINT:

  1. CHECK OTHER DTC OUTPUT (IN ADDITION TO DTC P0776) 
    1. Connect Techstream to the DLC3.
    2. Turn the ignition switch ON and turn the tester ON.
    3. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.
    4. Read the DTCs using the tester.

      Result 

      DTC RESULT DESCRIPTION

      Display (DTC output) Proceed to
      Only P0776 is output A
      P0776 and other DTCs are output B

      HINT:

      If any other codes besides P0776 are output, perform troubleshooting for those DTCs first.

    B: GO TO DTC CHART 

    A: Go to Next Step 

  2. INSPECT SHIFT SOLENOID VALVE SL2 
    1. Remove the shift solenoid valve SL2.

    3. Measure the resistance of the solenoid valve.

      Standard resistance: 

      5.0 to 5.6 Ω at 20°C (68°F) 

    4. Connect the battery's positive (+) lead with a 21 W bulb to terminal 2 and the negative (-) lead to terminal 1 of the solenoid valve connector. Then check that the valve moves and makes an operating noise.

      OK: Valve moves and makes operating noise. 

    NG: REPLACE SHIFT SOLENOID VALVE SL2 

    OK: Go to Next Step 

  3. INSPECT TRANSMISSION VALVE BODY ASSEMBLY 
    1. Check the transmission valve body assembly.

      OK: There are no foreign objects on each valve. 

    NG: REPAIR TRANSMISSION VALVE BODY ASSEMBLY 

    OK: Go to Next Step 

  4. INSPECT TORQUE CONVERTER CLUTCH ASSEMBLY 
    1. Check the torque converter clutch assembly (see TORQUE CONVERTER AND DRIVE PLATE  ).

      OK: The torque converter clutch operates normally. 

    NG: REPLACE TORQUE CONVERTER CLUTCH ASSEMBLY 

    OK: REPAIR OR REPLACE AUTOMATIC TRANSAXLE ASSEMBLY
