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. Then wait at least 10 seconds before performing the next test.
1.CHECK DTC DETECTION
With CONSULT-III
1. Start the engine.
2. Select "Data Monitor" in "TRANSMISSION".
3. Drive vehicle and maintain the following conditions for at least 10 minutes (total). (It is not necessary to maintain continuously.)

VHCL/S SE-A/T : 10 km/h (6 MPH) or more
ACCELE POSI : More than 1.0/8
SLCT LVR POSI : "D" position

With GST
Follow the procedure "With CONSULT-III".
Is "P1710" detected?
YES - Go to P1710.
NO - Check intermittent incident. Refer to Intermittent Incident.




Diagnosis Procedure
1.CHECK A/T FLUID TEMPERATURE SENSOR 1 SIGNAL
With CONSULT-III
1. Start the engine.
2. Select "Data Monitor" in "TRANSMISSION".
3. Check "ATF TEMP SE 1" and "ATF TEMP SE 2" values.





Which item is abnormal?
ATF TEMP SE 1-GO TO 2.
ATF TEMP SE 2-GO TO 5.
2.CHECK A/T FLUID TEMPERATURE SENSOR 1
1. Remove control valve with TCM. Refer to Exploded View.
2. Disconnect park/neutral position switch connector.
3. Check A/T fluid temperature sensor 1. Refer to P1710.
Is the inspection result normal?
YES - GO TO 3.
NO - Repair or replace damaged parts. Refer to Exploded View.
3.CHECK SUB-HARNESS
1. Disconnect TCM connector.
2. Check continuity between transmission range switch connector terminals and TCM connector terminals.





Is the inspection result normal?
YES - GO TO 4.
NO - Repair or replace damaged parts.
4.DETECT MALFUNCTIONING ITEM
Check the following.
- Check terminals of transmission range switch connector and TCM connector and harness cladding for damage.
- Check connector for loose connection.
Is the inspection result normal?
YES - GO TO 8.
NO - Repair or replace damaged parts.
5.CHECK A/T FLUID TEMPERATURE SENSOR 2
1. Remove A/T fluid temperature sensor 2. Refer to Exploded View.
2. Check A/T fluid temperature sensor 2. Refer to P1710.
Is the inspection result normal?
YES - GO TO 6.
NO - Repair or replace damaged parts. Refer to Exploded View.
6.CHECK TERMINAL CORD ASSEMBLY
1. Remove control valve with TCM. Refer to Exploded View.
2. Disconnect TCM connector.
3. Check continuity between A/T fluid temperature sensor 2 connector terminals and TCM connector terminals.





Is the inspection result normal?
YES - GO TO 7.
NO - Repair or replace damaged parts.
7.DETECT MALFUNCTIONING ITEM
Check the following.
- Check terminals of A/T fluid temperature sensor 2 connector and TCM connector, and harness cladding for damage.
- Check connector for loose connection.
Is the inspection result normal?
YES - GO TO 8.
NO - Repair or replace damaged parts.
8.CHECK TCM POWER SUPPLY AND GROUND CIRCUIT
Check TCM power supply and ground circuit. Refer to Main Power Supply and Ground Circuit.
Is the inspection result normal?
YES - Replace the control valve with TCM. Refer to Exploded View.
NO - Repair or replace damaged parts.




Component Inspection (A/T fluid temperature sensor 1)
1.CHECK A/T FLUID TEMPERATURE SENSOR 1
Check resistance between transmission range switch connector terminals.





Is the inspection result normal?
YES - INSPECTION END
NO - Replace control valve with TCM. Refer to Exploded View.




Component Inspection (A/T fluid temperature sensor 2)
1.CHECK A/T FLUID TEMPERATURE SENSOR 2
Check resistance between A/T fluid temperature sensor 2 connector terminals.





Is the inspection result normal?
YES - INSPECTION END
NO - Replace the A/T fluid temperature sensor 2. Refer to Exploded View.
