DTC CONFIRMATION PROCEDURE
CAUTION:
Be careful of the driving speed.
1.PREPARATION BEFORE OPERATION (PART 1)
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.PREPARATION BEFORE OPERATION (PART 2)
With CONSULT
1. Start the engine.
2. Select “Data Monitor” in “TRANSMISSION”.
3. Select “FLUID TEMP”.
4. Confirm that the CVT fluid temper ature is in the following range.
With GST
1. Start the engine.
2. Set the CVT fluid to 10 °C (50° F) or more.
NOTE:
When the ambient temperature is 20 °C (68° F), the CVT fluid usually increases to 50 to 80 °C (122 to
176° F) with driving in an urban area for approximately 10 minutes.
Is the CVT fluid 10
°C (50°F) or more?
YES >> GO TO 3.
NO >> 1. Warm the transaxle. 2. GO TO 3.
3.CHECK DTC DETECTION
1. Drive the vehicle.
2. Maintain the following conditions for 10 seconds or more.
3. Stop the vehicle.
4. Check the first trip DTC.
Is
“P0740” detected?
YES >> Go to TM-168, "Diagnosis Procedure".
NO >> INSPECTION END
