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.
2
Gear shift solenoid valve No.2 circuit check
1)With ignition “OFF”, disconnect “E495” and “E496” connectors from TCM and gear shift solenoid valve No.2 connector.
2)Check for proper terminal connection to “E495” and “E496” connectors and gear shift solenoid valve No.2 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 shift solenoid valve No.2 connector: infinity
•Voltage of “A1” and “A2” circuits: approx. 0 V (When ignition is “ON”).
Is check result OK?
Replace gear shift solenoid valve No.2 (solenoid valve unit). icon 
If this DTC is detected again, replace TCM and recheck DTC. icon 
Repair or replace defective wire harness.
