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 detected in this “DTC Confirmation Procedure”.

—Line pressure sensor (P0932-12 and P0932-14)

1)Start engine and drive vehicle.

DTC Troubleshooting

Step	Action	Yes	No
1	Is DTC P0942-09 and P0942-7B detected after performing “DTC Confirmation Procedure”?	Go to Step 2.	Check for intermittent trouble.
2	Solenoid valve unit check 1)Check that there is no hydraulic actuator fluid leakage. Is check result OK?	Replace TCM and recheck DTC.	Replace defective part (solenoid valve unit).
