DTC Detecting Condition and Trouble Area

DTC detecting condition	Trouble area
P19BA-22: Leakage with All Valve Switch Off – Signal Amplitude > Maximum Hydraulic circuit leaks excessively with all solenoid valves switched off. (1 D/C detection logic but transmission warning light does not light up)	•Solenoid valve unit •TCM
P19BA-61: Leakage with Only Odd Clutch Solenoid in Regulation – Signal Calculation Failure Hydraulic circuit leaks excessively when odd gear clutch is operated. (1 D/C detection logic but transmission warning light does not light up)
P19BA-62: Leakage with Only Even Clutch Solenoid in Regulation – Signal Compare Failure Hydraulic circuit leaks excessively when even gear clutch is operated. (1 D/C detection logic but transmission warning light does not light up)
P19BA-64: Leakage Shifter – Signal Plausibility Failure Hydraulic circuit for shift device leaks excessively. (1 D/C detection logic but transmission warning light does not light up)

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 P932-14)
—Hydraulic pressure (P0942-09 and P0942-7B)

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	Hydraulic actuator fluid leakage check 1)Check of actuator fluid leakage in each of solenoid valves. Is check result OK?	Replace TCM and recheck DTC.	Replace solenoid valve unit and recheck DTC.
