(1) Disconnect the connector, and measure at the wiring harness side.
(2) Measure the voltage between the PHEV-ECU connector (terminal BAT) and body ground.OK: Approximately 12 volts (battery positive voltage).
Is the check result normal?
Go to Step 4. Go to Step 3.
STEP 3. Check the power supply line for open circuit and short circuit (ETACS-ECU and the PHEV-ECU).
STEP 4. Test the OBD-II drive cycle.
STEP 5. Test the OBD-II drive cycle.
STEP 6. 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 1 . (2) Check the DTC.
