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
FLUID TEMP : 10В°C (50В°F) or more
With GST
NOTE:
When the ambient temperature is 20В°C (68В°F), the CVT fluid usually increases to 50 to 80В°C (122 to 176В°F) with driving in an urban area for approximately 10 minutes.
Is the CVT fluid 10В°C (50В°F) or more? YES >> GO TO 3.
NO >> 1. Warm the transaxle.
2. GO TO 3.
3.CHECK DTC DETECTION
Selector lever : “D” position
Vehicle speed : 40 km/h (25 MPH) or more
