Inspection Procedure 10: Charging does not start, or the charging indicator is not illuminated when the charger is connected to domestic power supply.

REGULAR CHARGING CONTROL SYSTEM CIRCUIT

COMMENTS ON TROUBLE SYMPTOM

The cause is assumed to be low environment temperature at charging.

PROBABLE CAUSES

Damaged wiring harness or connector(s)
Malfunction of the fuse and fusible link
Malfunction of the charging cable
Malfunction of the on board charger/DC-DC converter
Malfunction of the domestic power supply facility

DIAGNOSIS PROCEDURE

STEP 1. Charging cable check

Check if the fault indication of the electric leakage breaker incorporated in the charging cable is flashing.

Q. Is the check result normal?

	Go to Step 2.

	Replace the charging cable.

STEP 2. Voltage measurement at C-106 EV-ECU connector

(1)Disconnect the connector and measure at the wiring harness side.

(2)Measure the voltage between the C-106 EV-ECU connector terminal No. 1 and the earth.
OK: Battery voltage

Q. Is the check result normal?

	Go to Step 4.

	Go to Step 3.

STEP 3. Check the wiring harness between C-106 EV-ECU connector terminal No. 1 and the fusible link No. 25.

Check the power supply line for open circuit and short circuit.

note

Before the wiring harness check, check B-301 and B-310 junction block connector, and repair if necessary.

Q. Is the check result normal?

	Intermittent malfunction (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunction .)

	Repair the wiring harness. Then go to Step 4.

STEP 4. Check whether the diagnosis code is set.

Check if the diagnosis code is set to the EV-ECU.

Q. Is the diagnosis code set?

	Carry out the troubleshooting for the relevant diagnosis code. (Refer to .)

	Go to Step 5.

STEP 5. Charging lamp check

Check that the charging lamp flashes when the charging cable is connected, and it is illuminated permanently when the charging starts.

Q. Is the check result normal?

	Intermittent malfunction (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunction .)

	Check the charging cable. (Refer to .) Then go to Step 6.

STEP 6. Connector check: G-03 regular charging connection, G-04 earth connector, G-11 on board charger/DC-DC converter connector

Q. Is the check result normal?

	Go to Step 7.

	Repair the damaged connector. Or replace the EV charger cable (regular charging). (Refer to .)

STEP 7. Check the wiring harness between G-03 regular charging connection terminal No. 1, 2, 4, 5 to G-11 on board charger/DC-DC converter connector terminal No. 1, 2, G-04 earth connector terminal No. 3 and the body earth.

Check the power supply and earth lines for open circuit.

Q. Is the check result normal?

	Go to Step 8.

	Repair the wiring harness. Or replace the EV charger cable (regular charging). (Refer to .)

STEP 8. Connector check: C-106 EV-ECU connector, E-03 on board charger/DC-DC converter connector

Q. Is the check result normal?

	Go to Step 9.

	Repair the damaged connector.

STEP 9. Check the wiring harness between C-106 EV-ECU connector terminal No. 11 and E-03 on board charger/DC-DC converter connector terminal No. 12.

Check the signal lines for open circuit.

Q. Is the check result normal?

	Go to Step 10.

	Repair the wiring harness.

STEP 10. Check the wiring harness between E-03 on board charger/DC-DC converter connector terminal No. 7 and relay box fuse (No. 11).

Check the signal lines for open circuit.

Q. Is the check result normal?

	Go to Step 11.

	Repair the wiring harness.

STEP 11. Check the trouble symptom.

Q. Is the check result normal?

	The diagnosis is complete.

	Check the domestic power supply facility. Or replace the on board charger & DC/DC converter. (Refer to .)
