2. Connect the KDS to the self-diagnosis connector (DLC).
3. Turn ON the ignition switch.
4. Use the KDS device to perform forced operation.
5. Use a multimeter to ensure that the cooling fan is powered.

• Cooling fan B+ : cooling fan connector (4) pin
• Cooling fan ground : cooling fan connector (8) pin

6. Check the fan motor speed in the GSD device service data.

Specification : Refer to "Specification"

Warning

When checking the power supply of the cooling fan, check measure using the of the cooling fan connector (A).

(Reason : Wire / fuse break, Purpose of preventing improper maintenance due to connector contact failure etc.)

Cooling Fan #1

Cooling Fan #2

Description

Plug-in hybrid vehicle can be normal charge.

In the case of normal charge, the battery is charged after 220V AC power is transformed to DC power
by On-Board Charger (OBC).

While charging the vehicle, the driving of the vehicle is restricted.

Description

In normal charge, the battery is charged through the On-Board Charger (OBC) using external power
supply of 220V.

On-Board Charger (OBC) is the equipment that charges the high voltage battery of electric vehicle
using the 110 - 220V AC power.

1. Turn ignition switch OFF and disconnect the negative (-) battery cable.
2. Shut off the high voltage circuit.

   (Refer to Hybrid Control System - "High Voltage Shutoff Procedure")

3. Drain the coolant by loosening the drain plug.

   (Refer to Hybrid Motor System - "Coolant")

4. Remove the LH front wheel & tire and wheel house cover.
5. Remove the front bumper assembly.

   (Refer to Body - "Front Bumper Cover")

6. Disconnect the OBC cable connector (A).

7. Disconnect the OBC signal connector (B).

8. Disconnect the OBC coolant hose (A) and coolant hose quick-connector.

9. Remove the OBC mounting bolt (A) and nut (B).

OBC mounting bolt / nut : 23.5 - 24.5 N*m (2.4 - 2.5 kgf*m, 17.3 - 18.1 lb*ft)

10. Remove the OBC (C).
