MB992006: Extra fine probe

1.Check of the standard of the quick charger and external power supply equipment

Check whether the used quick charger or external power supply facility is compatible with the CHAdeMO standard.

Is the check result normal?

Use one compatible with CHAdeMO standard.

2.Visually check of the quick charge port

Visually check the quick charge port of EV home & quick charger cable (Refer to EV HOME & QUICK CHARGER CABLE VISUAL INSPECTION

Is the check result normal?

Replace the EV home & quick charger cable (Refer to EV HOME & QUICK CHARGER CABLE REMOVAL AND INSTALLATION

3.Check of wiring harness between On Board Charger (OBC)/DC-DC converter and quick charge port (charging start/stop signal 1 line, charging start/stop signal 2 line, charging permission/prohibition signal line)

(1) Check the following wiring harness for short to ground circuit.

Short to ground circuit between On Board Charger (OBC)/DC-DC converter connector (No. 2 terminal) and quick charge port connector (No. 4 terminal)
Short to ground circuit between On Board Charger (OBC)/DC-DC converter connector (No. 9 terminal) and quick charge port connector (No. 10 terminal)

(2) Check the following wiring harness for open circuit.

Open circuit between On Board Charger (OBC)/DC-DC converter connector (No. 2 terminal) and quick charge port connector (No. 4 terminal)
Open circuit between On Board Charger (OBC)/DC-DC converter connector (No. 9 terminal) and quick charge port connector (No. 10 terminal)
Open circuit between On Board Charger (OBC)/DC-DC converter connector (No. 3 terminal) and quick charge port connector (No. 6 terminal)

Is the check result normal?

Repair the connector(s) or wiring harness, or replace the EV home & quick charger cable (Refer to EV HOME & QUICK CHARGER CABLE REMOVAL AND INSTALLATION

4.Check of wiring harness between On Board Charger (OBC)/DC-DC converter and quick charge port (charging start/stop signal 1 line)

(1) Disconnect the On Board Charger (OBC)/DC-DC converter connector (B532), and measure at the wiring harness side.

(2) Change the power supply mode of the electric motor switch to ON (READY indicator: OFF).

(3) Measure the voltage between the following terminals.

Voltage between On Board Charger (OBC)/DC-DC converter connector (No. 2 terminal) and body ground

OK: 1 V or less

Is the check result normal?

Repair the connector(s) or wiring harness, or replace the EV home & quick charger cable.

5.Check whether the DTC is set again.

(1) Erase the set DTC.

(2) Perform quick charging (external power supplly).

(3) Check whether the DTC is set again.

Is the DTC set?

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

6.Check whether the DTC is set again.

(1) Erase the set DTC.

(2) Charge the drive battery by using the quick charger (external power supply equipment) other than the defective one.

(3) Check whether the DTC is set again.

Is the DTC set?

Replace the On Board Charger (OBC)/DC-DC converter (Refer to ON BOARD CHARGER (OBC) &DC-DC CONVERTER REMOVAL AND INSTALLATION

Ask the user to inspect the quick charger/external power supply equipment.
