POSSIBLE CAUSE
  • Secondary pressure solenoid valve (control valve)
  • CVT belt
 
 
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
cautionAlways drive vehicle at a safe speed.
The MIL is ON and ONLY DTC P0776–00 (PC SOLENOID B - Pressure Control Solenoid “B” Performance/Stuck OFF) is stored in the TCM.
noteIf this issue should occur, the vehicle may hesitate and/or have a lack of power.
1.CHECK DTC PRIORITY
When DTC P0776–00 is displayed together with P17F0–07, diagnose first the P17F0–07.
Is "P17F0–07" detected?
Perform diagnosis of P17F0–07. Refer to Diagnosis ProcedureDTC Diagnosis Procedure.
.
 
2.PREPARATION BEFORE WORK
If another “DTC CONFIRMATION PROCEDURE” occurs just before, the ignition switch is OFF and wait for at least 10 seconds, then perform the next test.

3.CHECK DTC DETECTION
  1. Start the engine.
  2. Drive the vehicle.
  3. Maintain the following condition for 20 seconds or more.
    Shift position: “D” position
    Vehicle speed: 40 km/h (25 MPH) or more
    Accelerator pedal position: 1.0/8 or more
  4. Stop the vehicle.
  5. Check the first trip DTC.
Is “P0776–00” detected?
