STEP 1. Using scan tool (M.U.T.-IIISE), diagnose CAN bus line.
STEP 2. Check the V2H relay.
STEP 3. Check the power supply line for short to ground (The V2H relay connector and the quick charging connector).
STEP 4. Voltage measurement at the V2H relay connector.
(1) Remove the V2H relay, and measure at the relay box side.
(2) Turn on the power supply mode of the electric motor switch.
(3) Measure the voltage between terminal No.1 and body ground.OK: System voltage
Is the check result normal?
Go to Step 5. Repair the connector or wiring harness.
STEP 5. Check the V2HR line for open and short to ground (The V2H relay connector and the PHEV-ECU connector).
STEP 6. Using scan tool (M.U.T.-IIISE), check whether the DTC is set again.
(1) Erase the DTC.
(2) Turn on the power supply mode of the electric motor switch.
(3) Check if the DTC is set.
Is the DTC set?
Replace the PHEV-ECU (Refer to ). The trouble can be an intermittent malfunction (Refer to GROUP 00, How to Cope with Intermittent Malfunction ).
