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.

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	Gear select solenoid valve circuit check 1)With ignition “OFF”, disconnect “E495” and “E496” connectors from TCM and gear select solenoid valve connector. 2)Check for proper terminal connection to “E495” and “E496” connectors and gear select solenoid valve connector. 3)If connections are OK, check the following points. •Resistance of “A1” and “A2” circuits: less than 1 Ω •Resistance between “A1” and “A2” circuits and ground: infinity •Resistance between “A1” circuit terminal and “A2” circuit terminal at gear select solenoid valve connector: infinity •Voltage of “A1” and “A2” circuits: approx. 0 V (When ignition is “ON”). Is check result OK?	Replace gear select solenoid valve (solenoid valve unit). If this DTC is detected again, replace TCM and recheck DTC.	Repair or replace defective wire harness.
