1. CHECK DTC OUTPUT (IN ADDITION TO DTC P0729) Connect the Techstream to the DLC3. Turn the engine switch on (IG). Turn the Techstream on. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes. Read the DTCs using the Techstream. RESULT Result Proceed to Only P0729 is output A P0729 and other DTCs are output B HINT: If any other codes besides P0729 are output, perform troubleshooting for those DTCs first. B --> See step 5 A: Go to next step
2. PERFORM ACTIVE TEST USING TECHSTREAM (RUNNING TEST) WARNING: This test should always be performed with at least 2 people. NOTE: Perform the test at the normal operating ATF temperature: 50 to 80°C (122 to 176°F). Perform the test with the A/C turned off. HINT: Using the Techstream to perform Active Tests allows relays, VSVs, actuators and other items to be operated without removing any parts. This non-intrusive functional inspection can be very useful because intermittent operation may be discovered before parts or wiring is disturbed. Performing Active Tests early in troubleshooting is one way to save diagnostic time. Data List information can be displayed while performing Active Tests. Connect the Techstream to the DLC3. Clear the DTC. Refer to «DTC CHECK / CLEAR»(ref-385197-S07537012942011021400000) . Warm up the engine. Enter the following menus: Powertrain / Engine and ECT / Active Test. According to the display on the Techstream, perform the Active Test. HINT: While driving, the shift position can be forcibly changed with the Techstream. Comparing the shift position commanded by the Active Test with the actual shift position enables you to confirm the problem. Refer to «FAIL-SAFE CHART»(ref-385197-S14012301422011021400000) . ENGINE AND ECT Tester Display Test Part Control Range Diagnostic Note Control the Shift Position Operate shift solenoid valve and set each shift position Press "-->" button: Shift up Press "<--" button: Shift down It is possible to check the operation of the shift solenoid valves. [Vehicle Condition] The vehicle speed is 50 km/h (31 mph) or less. HINT: This test can be conducted when the vehicle speed is 50 km/h (31 mph) or less. The 4th to 5th and 5th to 6th up-shifts must be performed with the accelerator pedal released. The 6th to 5th and 5th to 4th down-shifts must be performed with the accelerator pedal released. Do not operate the accelerator pedal for at least 2 seconds after shifting and do not shift successively. The shift position commanded by the ECM is shown in the Data List display on the Techstream.

3. PERFORM ACTIVE TEST USING TECHSTREAM (SHIFT SOLENOID VALVE SLT) NOTE: Perform the test at the normal operating ATF temperature: 50 to 80°C (122 to 176°F). Be careful to prevent SST hose from interfering with the exhaust pipe. Perform the test with the A/C turned off. HINT: Using the Techstream to perform Active Tests allows relays, VSVs, actuators and other items to be operated without removing any parts. This non-intrusive functional inspection can be very useful because intermittent operation may be discovered before parts or wiring is disturbed. Performing Active Tests early in troubleshooting is one way to save diagnostic time. Data List information can be displayed while performing Active Tests. Remove the test plug on the transmission case center right side and connect SST. SST: 09992-00095 09992-00231 09992-00271 Connect the Techstream to the DLC3. Start the engine and warm it up. Measure the line pressure with SST. Turn the Techstream on. Enter the following menus: Powertrain / Engine and ECT / Active Test. According to the display on the Techstream, perform the Active Test. Measure the line pressure. ENGINE AND ECT Tester Display Test Part Control Range Diagnostic Note Activate the Solenoid (SLT)* Operate shift solenoid valve SLT and raise line pressure ON or OFF HINT: OFF: Line pressure up (when Active Test "Activate the Solenoid (SLT)" is performed, ECM commands shift solenoid valve SLT to turn OFF) ON: No action (normal operation) [Vehicle Condition] The vehicle is stopped. The engine is idling. HINT: *: Activate the Solenoid (SLT) in the Active Test is performed to check the line pressure changes by connecting SST to the automatic transmission, which is used in the Hydraulic Test. Refer to «HYDRAULIC TEST»(ref-385197-S07014838072011021400000) as well. Note that the pressure values in the Active Test and hydraulic test are different.

1. ACTIVE TEST HINT: Using the Techstream to perform Active Tests allows relays, VSVs, actuators and other items to be operated without removing any parts. This non-intrusive functional inspection can be very useful because intermittent operation may be discovered before parts or wiring is disturbed. Performing Active Tests early in troubleshooting is one way to save diagnostic time. Data List information can be displayed while performing Active Tests. Warm up the engine. Turn the engine switch off. Connect the Techstream to the DLC3. Turn the engine switch on (IG). Turn the Techstream on. Enter the following menus: Powertrain / Engine and ECT / Active Test. According to the display on the Techstream, perform the Active Test. ENGINE AND ECT Tester Display Test Part Control Range Diagnostic Note Activate the Lock Up Control shift solenoid valve SLU to set automatic transmission to lock-up condition ON or OFF It is possible to check the shift solenoid valve SLU operation. [Vehicle Condition] The throttle valve opening angle is less than 35%. The vehicle speed is 60 km/h (37 mph) or more. HINT: This test can be conducted when the vehicle speed is 60 km/h (37 mph) or more. Perform this test while driving in 5th or 6th gear. Lightly depress the accelerator pedal and check that the engine speed does not change abruptly. HINT: When changing the accelerator pedal opening angle while driving, if the engine speed does not change abruptly, lock-up is on. Slowly release the accelerator pedal in order to decelerate, but do not fully release the pedal (fully releasing the pedal will close the throttle valve and lock-up may be turned off automatically).

1. CHECK DTC OUTPUT (IN ADDITION TO DTC P2757) Connect the Techstream to the DLC3. Turn the engine switch on (IG). Turn the Techstream on. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes. Read the DTCs using the Techstream. RESULT Result Proceed to Only P2757 is output A P2757 and other DTCs are output B HINT: If any other codes besides P2757 are output, perform troubleshooting for those DTCs first.
