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. Start the engine.
2. Select "DATA MONITOR".
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 ATF TEMP SEN/CIRC" detected?
YES >> Go to TM-147, "Diagnosis Procedure".
NO >> Check Intermittent incident. Refer to, "Intermittent Incident". Testing and Inspection
Diagnosis Procedure
1. CHECK A/T FLUID TEMPERATURE SENSOR 1 SIGNAL
With CONSULT-III
1. Start engine.
2. Select "DATA MONITOR".
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 4.
2. CHECK A/T FLUID TEMPERATURE SENSOR 1
Check A/T fluid temperature sensor 1. Refer to, "Component Inspection (A/T fluid temperature sensor)
Is the inspection result normal?
YES >> GO TO 3.
NO >> Replace the control valve with TCM.
3. CHECK SUB-HARNESS
1. Disconnect park/neutral position switch connector and TCM connector.
2. Check continuity between park/neutral position switch connector and TCM connector.
3. If OK, check harness for short to ground and short to power.
Is the inspection result normal?
YES >> GO TO 6.
NO >> Replace open circuit or short to ground and short to power in harness or connectors.
4. CHECK A/T FLUID TEMPERATURE SENSOR 2
Check A/T fluid temperature sensor 2. Refer to, "Component Inspection (A/T fluid temperature sensor)
Is the inspection result normal?
YES >> GO TO 5.
NO >> Replace the A/T fluid temperature sensor 2.
5. CHECK TERMINAL CORD ASSEMBLY
1. Disconnect A/T fluid temperature sensor 2 connector and TCM connector.
2. Check continuity between A/T fluid temperature sensor 2 connector terminals and TCM connector terminals.
3. If OK, check harness for short to ground and short to power.
Is the inspection result normal?
YES >> GO TO 6.
NO >> Replace open circuit or short to ground and short to power in harness or connectors.
6. CHECK TCM POWER SUPPLY AND GROUND CIRCUIT
Check TCM power supply and ground circuit. Refer to, "Diagnosis Procedure".
Is the inspection result normal?
YES >> Replace the control valve with TCM.
NO >> Repair or replace damaged parts.
Component Inspection (A/T fluid temperature sensor 1)
1. CHECK A/T FLUID TEMPERATURE SENSOR 2
1. Remove control valve with TCM.
2. Check resistance between park/neutral position switch connector terminals.
Is the inspection result normal?
YES >> INSPECTION END
NO >> Replace control valve with TCM.
Component Inspection (A/T fluid temperature sensor 2)
1. CHECK A/T FLUID TEMPERATURE SENSOR 2
1. Remove A/T fluid temperature sensor 2.
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.
