DTC COFIRMATION PROCEDURE
CAUTION:
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.CHECK DTC DETECTION
Selector lever : "D" position
Accelerator pedal position : 0.7/8 or more
Vehicle speed : 45 km/h (28 MPH) or more
Is "P2859" detected?
YES >> Go to TM "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis Procedure
1.CHECK INTERMITTENT INCIDENT
Refer to GI "Intermittent Incident".
Is the inspection result normal?
YES >> Replace transaxle assembly. Refer to TM "Removal and Installation".
NO >> Repair or replace malfunctioning parts.
