1.Front transaxle fluid leak check
Visually check that there is no fluid leaks from the front transaxle.
Is the check result normal?
Repair or replace the front transaxle assembly (Refer to Transaxle - Front Transaxle REMOVAL AND INSTALLATION). Then,
 
2.Front transaxle fluid level check
Check the fluid level by looking the fluid surface from the filler plug hole of the front transaxle.
Is the check result normal?
Refill the fluid (Refer to Transaxle - Transaxle Fluid Change TRANSAXLE FLUID CHANGE). Then,
 
3.Test the OBD-II drive cycle.
(1) Carry out a test drive with the drive cycle pattern. Refer to OBD-II Drive Cycle OBD-II DRIVE CYCLE.
(2) Check the DTC.
Is the DTC set?
Replace the valve body assembly (Refer to Transaxle Overhaul - Front Transaxle DISASSEMBLY AND ASSEMBLY), Then,
The trouble can be an intermittent malfunction (Refer to General Information - How to Use Troubleshooting/Inspection Service Points, How to Cope with Intermittent Malfunctions HOW TO COPE WITH INTERMITTENT MALFUNCTIONS).
 
4.Test the OBD-II drive cycle.
(1) Carry out a test drive with the drive cycle pattern. Refer to OBD-II Drive Cycle OBD-II DRIVE CYCLE.
(2) Check the DTC.
Is the DTC set?
Replace the front transaxle assembly (Refer to Transaxle - Front Transaxle REMOVAL AND INSTALLATION), Then,
The procedure is complete.
 
5.Test the OBD-II drive cycle.
(1) Carry out a test drive with the drive cycle pattern. Refer to OBD-II Drive Cycle OBD-II DRIVE CYCLE.
(2) Check the DTC.
Is the DTC set?
Replace the PHEV-ECU (Refer to PHEV-ECU REMOVAL AND INSTALLATION). Then,
The procedure is complete.
 
6.Test the OBD-II drive cycle.
(1) Carry out a test drive with the drive cycle pattern. Refer to OBD-II Drive Cycle OBD-II DRIVE CYCLE.
(2) Check the DTC.
Is the DTC set?
Retry the troubleshooting.
The procedure is complete.
