DTC Confirmation Procedure

WARNING:

If you do not select a suitable route and take proper precautions when performing a road test, an accident can occur.

•Select a level road with no traffic to minimize the risk of accident.
•Perform the test extremely carefully.
•Perform the road test with 2 persons, a driver and a tester.

NOTE:

•Check that the following condition is satisfied in this procedure.

—11 V < Battery voltage < 15 V

•Check that the following DTCs are not detected in this “DTC Confirmation Procedure”.

—Parking position sensor (P081C-11, P081C-15, P081C-36, P081C-37, P081C-38 and P19B7-68)
—1st & 3rd gear position sensor (P0914-11, P0914-15, P0914-1C, P0914-36, P0914-37 and P0914-38)
—5th & reverse gear position sensor (P0916-11, P0916-15, P0916-1C, P0916-36, P0916-37 and P0916-38)
—Line pressure sensor (P0932-12 and P0932-14).
—Sensor supply voltage (P19A7-1C)

1)Start engine and drive vehicle.

DTC Troubleshooting

Step	Action	Yes	No
1	Was “Twin Clutch System Check” performed?	Go to Step 2.	Go to Twin Clutch System Check.
2	Odd gear clutch position sensor power supply circuit check 1)With ignition “OFF”, disconnect odd gear clutch position sensor connector. 2)Check for proper terminal connection to odd gear clutch position sensor connector. 3)If connection is OK, set ignition “ON”. 4)Check that voltage between “A1” and ground is approx. 5 V. Is check result OK?	Go to step 3.	Repair “A1” circuit. If this DTC is detected again, replace TCM and recheck DTC.
3	Odd gear clutch position sensor signal circuit and ground circuit check 1)With ignition “OFF”, disconnect “E495” and “E496” connectors from TCM. 2)Check for proper terminal connection to “E495” and “E496” connectors. 3)If connections are OK, check the following points. •Resistance of “A2” and “A3” circuits: less than 1 Ω •Resistance between each of “A2” and “A3” circuits and ground: infinity •Resistance between “A3” circuit terminal and other terminal at odd gear clutch position sensor connector: infinity •Voltage of “A2” and “A3” circuits: approx. 0 V (When ignition is “ON”) Is check result OK?	Replace odd gear clutch position sensor (solenoid valve unit). If this DTC is detected again, replace TCM and recheck DTC.	Repair or replace defective wire harness.
