DIAGNOSIS
STEP 1. Using scan tool (M.U.T.-IIISE), check whether the other DTC is set.
Check whether the DTC is set in the BMU or on board charger/DC-DC converter (Refer to <BMU>, <On board charger/DC-DC converter>).
Is the DTC set?
Troubleshoot for the relevant DTC. Then go to Step 3.
Go to Step 2.
 
STEP 2. Test the OBD-II drive cycle.
(1) Carry out a test drive with the drive cycle pattern. Refer to Diagnostic Function - OBD-II Drive Cycle - Pattern 7 .
(2) Check the DTC.
Is the DTC set?
Replace the PHEV-ECU (Refer to ). Then go to Step 3.
The trouble can be an intermittent malfunction (Refer to GROUP 00, How to Cope with Intermittent Malfunction ).
 
STEP 3. Test the OBD-II drive cycle.
(1) Carry out a test drive with the drive cycle pattern. Refer to Diagnostic Function - OBD-II Drive Cycle - Pattern 7 .
(2) Check the DTC.
Is the DTC set?
Retry the troubleshooting.
The inspection is complete.
