DTC CONFIRMATION PROCEDURE

1.PREPARATION BEFORE WORK

If another “DTC CONFIRMATION PROCEDURE” occurs just before, turn ignition switch OFF and wait for at least 10 seconds, then perform the next test.

>> GO TO 2.

2.INSPECTION START

Is it necessary to erase permanent DTC? YES >> GO TO 3.

NO >> GO TO 7.

3.CHECK DTC (ECM AND TCM)

Check the DTC.

Is any DTC other than “P0711” detected? YES >> Check DTC detected item. Refer to EC-94, "DTC Index" (ECM), TM-126, "DTC Index" (TCM).

NO >> GO TO 4.

4.PERFORM DTC Confirmation procedure (part 1)

TESTING CONDITION:

With CONSULT


  1. Move the vehicle to a cool place.

NOTE:

Cool the vehicle in an environment of ambient air temperature between −10В°C (14В°F) and 35В°C (95В°F).

  1. Turn ignition switch OFF and leave the vehicle for 12 hours.

CAUTION:

Never turn ignition switch ON during this procedure.

NOTE:

The vehicle must be cooled with the food open.

  1. Turn ignition switch ON.

CAUTION:

Never start the engine.

  1. Select “Data Monitor” in “TRANSMISSION”.
  2. Select “FLUID TEMP”.
  3. Record CVT fluid temperature
  4. Start engine and let it idle for 5 minutes or more.

CAUTION:

Never turn ignition switch OFF during idling.

  1. Check 1st trip DTC.

With GST


  1. Move the vehicle to a cool place.

NOTE:

Cool the vehicle in an environment of ambient air temperature between −10В°C (14В°F) and 35В°C (95В°F).
