Charging System Insulation Resistance Inspection

1. Charge the vehicle with a working EVSE (regular charging station).
2. If unable to charge, check the EVSE (standard charger) status.
3. Is there a leakage current fault in the EVSE (standard charger)? Does the leakage circuit breaker of the electrical equipment work?

• Go to "Proximity Detection (PD) Signal Inspection" procedure.

No Good 

• Go to next procedure.

Inspection Condition	(+) Probe		(-) Probe		Specification
	Connector	Terminal	Connector	Terminal
Ignition "OFF". Disconnect main battery safety plug, and wait for 5 minutes. Check high voltage terminal is lower than 30V. See if the AC power high voltage cable connector is connected to the OBC.	Charging connector (5 pin)	1 (AC neutral)	Chassis ground	-	Above 10MΩ (mega Ω meter: when DC is 500V)
	Charging connector (5 pin)	2 (AC live)	Chassis ground	-	Above 10MΩ (mega Ω meter: when DC is 500V)

• If the measured value is normal when re-measure "Insulation Resistance of Charging System AC Input", thoroughly check the EVSE (standard charger).
• For further checking of the vehicle charging system, go to "Proximity Detection (PD) Signal Inspection" procedure.

No Good 

• Go to next procedure for more precise diagnosis.

	Connector	Terminal	Connector	Terminal
Ignition "OFF". Disconnect main battery safety plug, and wait for 5 minutes. Check high voltage terminal is lower than 30V. See if the AC power high voltage cable connector is connected to the OBC.	OBC (component side)	1 (AC neutral)	Chassis ground	-	Above 10MΩ (mega Ω meter: when DC is 500V)
	OBC (component side)	3 (AC live)	Chassis ground	-	Above 10MΩ (mega Ω meter: when DC is 500V)

Good 

• Carefully re-do "Charging System Insulation Resistance Inspection" procedure.
• Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.

No Good 

• Replace the "OBC" with a working one and than go to "Verification Of Repair " procedure.

Proximity Detection (PD) Signal Inspection
Inspection Condition	Inspection Procedure	Reference
Ignition "ON".	Connect KDS to "Data Link Connector (DLC)". Operate vehicle or system in accordance with Enable Condition in DTC Detecting Condition. Monitor "PD Status" and "Charging Plug Connection Status" parameters in "Current Data" with KDS during connect or remove charging connector. (do not charge the vehicle)	Fig.1 to 2

Good 

• Go to "Inlet Lock Device Inspection" procedure.

No Good 

• See if there is any foreign substance around the charger connector or charger terminal.
• Go to "IN CABLE CONTROL BOX (ICCB) INSPECTION " procedure.
