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”.

—Even gear clutch pressure sensor (P0642-13, P0933-12, P0933-14, P0934-1C and P0935-1C)
—Sensor module temperature sensor (P0668-11, P0668-15, P19D1-62 and P19D1-64)
—Odd gear clutch speed sensor (P0715-31, P0715-61, P0715-62 and P0715-64)
—Even gear clutch speed sensor (P0716-31, P0716-61, P0716-62 and P0716-64)
—Gear select position sensor (P0904-11, P0904-15, P0904-1C, P0904-36, P0904-37, P0904-38 and P0909-1C)
—2nd & 4th gear position sensor (P0915-11, P0915-15, P0915-1C, P0915-36, P0915-37 and P0915-38)
—5th & reverse gear position sensor (P0916-11, P0916-15, P0916-1C, P0916-36, P0916-37 and P0916-38)
—6th gear position sensor (P0917-11, P0917-15, P0917-1C, P0917-36, P0917-37 and P0917-38)
—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	1st & 3rd gear position sensor power supply circuit check 1)With ignition “OFF”, disconnect sensor module connector. 2)Check for proper terminal connection to sensor module 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	1st & 3rd gear 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 “A2” circuit terminal and other terminal at sensor module connector: infinity •Resistance between “A3” circuit terminal and other terminal at sensor module connector: infinity •Voltage of “A2” and “A3” circuits: approx. 0 V (When ignition is “ON”) Is check result OK?	Replace 1st & 3rd gear position sensor (solenoid valve unit). If this DTC is detected again, replace TCM and recheck DTC.	Repair or replace defective wire harness.
