DTC CONFIRMATION PROCEDURE
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
If “DTC CONFIRMATION PROCEDURE” has been previously performed, always turn ignition switch OFF and wait at least 10 seconds before performing the next test.
After the repair, perform the following procedure to confirm the malfunction is eliminated.
1.CHECK DTC DETECTION
With CONSULT-III
1. Turn ignition switch ON.
2. Select “DATA MONITOR” in “TRANSMISSION”.
3. Make sure that output voltage of CVT fluid temperature sensor is within the range below.
ATF TEMP SEN : 1.0 – 2.0 V If out of range, drive the vehicle to decrease the voltage (warm up the fluid) or stop engine to increase the voltage (cool down the fluid)
4. Start engine and maintain the following conditions for at least 10 consecutive seconds.
VEHICLE SPEED (accelerate slowly) : 0 → 50 km/h (31 MPH) ACC PEDAL OPEN : 0.5/8 – 1.0/8 RANGE : “D” position
Is “P0868” detected? YES >> Go to TM-234, "Diagnosis Procedure".
NO >> Check intermittent incident. Refer to GI-42, "Intermittent Incident".
Diagnosis Procedure
1.CHECK LINE PRESSURE
Perform line pressure test. Refer to TM-188, "Inspection and Judgment".
Is the inspection result normal? YES >> GO TO 2.
NO >> Repair or replace damaged parts. Refer to TM-188, "Inspection and Judgment".
2.CHECK SECONDARY PRESSURE SOLENOID VALVE
Check secondary pressure solenoid valve. Refer to TM-225, "DTC Logic".
Is the inspection result normal?
YES >> GO TO 3.
NO >> Repair or replace damaged parts.
3.CHECK LINE PRESSURE SOLENOID VALVE
Check line pressure solenoid valve. Refer to TM-219, "DTC Logic".
Is the inspection result normal? YES >> GO TO 4.
NO >> Repair or replace damaged parts.
4.CHECK SECONDARY PRESSURE SENSOR SYSTEM
Check secondary pressure sensor system. Refer to TM-230, "DTC Logic".
Is the inspection result normal? YES >> GO TO 5.
NO >> Repair or replace damaged parts.
5.CHECK TCM
Check input/output signal. Refer to TM-164, "Reference Value" Is the inspection result normal? YES >> Check intermittent incident. Refer to GI-42, "Intermittent Incident".
NO >> Replace the TCM. Refer to TM-280, "Removal and Installation".
