DTC CONFIRMATION PROCEDURE
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 line 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 wait for at least 5 consecutive seconds.
With GST
Follow the procedure “With CONSULT-III”.
Is “P0840” detected? YES >> Go to TM-230, "Diagnosis Procedure".
NO >> Check intermittent incident. Refer to GI-42, "Intermittent Incident".
Diagnosis Procedure
1.CHECK INPUT SIGNAL
1. Start engine.
2. Check voltage between TCM connector terminal and ground.
Is the inspection result normal? YES >> GO TO 6.
NO >> GO TO 2.
2.CHECK HARNESS BETWEEN TCM AND SECONDARY PRESSURE SENSOR
1. Turn ignition switch OFF.
2. Disconnect TCM connector and CVT unit harness connector.
3. Check continuity between TCM connector terminal and CVT unit harness connector terminal.
4. If OK, check harness for short to ground and short to power.
5. Reinstall any part removed.
Is the inspection result normal? YES >> GO TO 3.
NO >> Repair or replace damaged parts.
3.CHECK SENSOR POWER AND SENSOR GROUND
1. Connect TCM connector.
2. Turn ignition switch ON.
3. Check voltage between CVT unit harness connector terminals.
4. Reinstall any part removed.
Is the inspection result normal? YES >> GO TO 5.
NO >> GO TO 4.
4. CHECK HARNESS BETWEEN TCM AND CVT UNIT HARNESS CONNECTOR (SENSOR POWER AND SENSOR GROUND)
1. Turn ignition switch OFF.
2. Disconnect TCM connector.
3. Check continuity between TCM connector terminals and CVT unit harness connector terminals.
4. If OK, check harness for short to ground and short to power.
5. Reinstall any part removed.
Is the inspection result normal? YES >> GO TO 5.
NO >> Repair or replace damaged parts.
5. CHECK THE TCM SHORT
Replace same type TCM, perform self-diagnosis check. Erase self-diagnostic results and then start engine perform self-diagnosis check. Refer to TM-230, "DTC Logic".
Is “P0840” detected again? YES >> Replace the transaxle assembly. Refer to TM-301, "Removal and Installation".
NO >> Replace the TCM. Refer to TM-280, "Removal and Installation".
6.CHECK TCM
Check TCM input/output signals. 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".
