POSSIBLE CAUSE

Secondary pressure solenoid valve

FAIL-SAFE

When a malfunction occurs on the low oil pressure side

Selector shock is large
Start is slow
Acceleration is slow
Lock-up is not performed
Vehicle speed is not increased

When a malfunction occurs on the high oil pressure side

Selector shock is large
Start is slow
Acceleration is slow
Lock-up is not performed

DTC CONFIRMATION PROCEDURE

CAUTION: Always drive vehicle at a safe speed.

1.PREPARATION BEFORE WORK

If another “DTC CONFIRMATION PROCEDURE” occurs just before, turn ignition switch OFF and wait for at least 10 seconds, then perform the next test.

>> GO TO 2.

2.CHECK DTC DETECTION

Start the engine.
Drive the vehicle.
Maintain the following condition for 20 seconds or more.

Selector lever : “D” position
Vehicle speed : 40 km/h (25 MPH) or more
Accelerator pedal position : 1.0/8 or more

Stop the vehicle.
Check the first trip DTC.

Is “P0776” detected? YES >> Go to TM-140, "Diagnosis Procedure".

NO-1 >> To check malfunction symptom before repair: Refer to GI-41, "Intermittent Incident".

NO-2 >> Confirmation after repair: INSPECTION END

Diagnosis Procedure

1.REPLACE TRANSAXLE ASSEMBLY

Replace transaxle assembly. Refer to TM-220, "Removal and Installation".

>> WORK END
