Note. Perform the universal trip to clear permanent DTCs. Refer to DTC CHECK / CLEAR [03/2012 - ] . There is a possibility that the DTC P062F is issued from the ECUs of the ECM and TCM. Use Techstream to conduct a health check to confirm which ECU the DTC is issued from and then inspect the related system.

HINT

Using the Techstream to read the Data List allows the values or states of switches, sensors, actuators and other items to be read without removing any parts. This non-intrusive inspection can be very useful because intermittent conditions or signals may be discovered before parts or wiring is disturbed. Reading the Data List information early in troubleshooting is one way to save diagnostic time.

Note. In the table below, the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not.

  1. Warm up the engine.
  2. Turn the engine switch off.
  3. Connect the Techstream to the DLC3.
  4. Turn the engine switch on (IG).
  5. Turn the Techstream on.
  6. Enter the following menus: Powertrain / ECT / Data List.
  7. According to the display on the Techstream, read the Data List. Tester Display Measurement Item / Range Normal Condition Diagnostic Note Neutral Position SW Signal PNP switch status / ON or OFF ON: Shift lever is in P or N OFF: Shift lever is not in P or N When the shift lever position displayed on the Techstream differs from the actual position, adjustment of the PNP switch or the shift cable may be incorrect. Shift SW Status (R Range) PNP switch status / ON or OFF ON: Shift lever is in R OFF: Shift lever is not in R When the shift lever position displayed on the Techstream differs from the actual position, adjustment of the PNP switch or the shift cable may be incorrect. Shift SW Status (D Range) PNP switch status / ON or OFF ON: Shift lever is in D or S OFF: Shift lever is not in D or S When the shift lever position displayed on the Techstream differs from the actual position, adjustment of the PNP switch or the shift cable may be incorrect.

Note. Perform the universal trip to clear permanent DTCs. Refer to DTC CHECK / CLEAR [03/2012 - ] . If DTCs P0711 and P2610 are output simultaneously, confirm that the ATF temperature is as specified in "Normal Condition" using the Techstream first. When the ATF temperature is as specified in "Normal Condition", perform troubleshooting for DTC P2610. Refer to DIAGNOSTIC TROUBLE CODE CHART [03/2012 - 07/2012] . In the table below, the value listed under "Normal Condition" are reference values.

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.

[Vehicle Condition] Vehicle speed: 60 km/h (37 mph) or more [Lock-up] 0: OFF 1: ON Possible to check SLU and SL solenoid operation. HINT: This test can be conducted when the vehicle speed is 60 km/h (37 mph) or more. 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, lock-up is on. Slowly release, but not fully, the accelerator pedal in order to decelerate. (Fully releasing the pedal will close the throttle valve and lock-up may be turned off.)

  1. Refer to inspection procedure for CAN communication system.
  2. If the CAN communication malfunctions, the TCM cannot receive the current data from the ECM. In this case, the freeze frame data output from the TCM has not been updated, so the data will not be useful for the inspection. However, reading the Data List as the first step in troubleshooting is effective to find malfunctions.
  3. The malfunction area can be checked using the Bus Check function on the Techstream. Refer to «DIAGNOSIS SYSTEM [03/2012 - 07/2012]»(ref-602741-S17182073442014030500000) .
