High Voltage Shut-off Procedure
   
Be sure to read and follow the “General Safety Information and Caution” before doing any work related with the high voltage system. Failure to follow the safety instructions may result in serious electrical injuries.
   
High voltage components : High Voltage Battery, Power Relay Assembly (PRA), Quick Charge Relay Assembly (QRA), Motor, Power Cable, BMS ECU, Inverter, LDC, On-Board Charger (OBC), Main Relay, Pre-charge Relay, Pre-charge resistor, Battery Current Sensor, Safety Plug, Main Fuse, Battery Temperature Sensor, Busbar, Charge Port, A/C Compressor, Electric Power Control Unit (EPCU), High Voltage Heater, High Voltage Heater Relay etc.
1.
Turn the ignition switch OFF and disconnect the negative (-) terminal of the auxiliary battery.
2.
Remove the cover (A) on the floor carpet of the rear seat.

3.
After loosening the nut, remove the safety plug service cover (A).

Safety plug service cover mounting nut : 7.8 ~ 11.8 N.m (0.8 ~ 1.2 kgf.m, 5.8 ~ 8.7 lb-ft)

4.
Remove the safety plug (A).

   
Remove the safety plug in the follwing order.

5.
Wait at least 5 minutes or until the capacitor in the high voltage system is fully discharged.
6.
Measure the voltage between the inverter terminals to check that the capacitor in the inverter is discharged completely
(1)
Lift the vehicle.
(2)
Remove the high voltage battery lower cover (A) by loosening the bolt.

(3)
Remove the high voltage cable (A).

(4)
Measure the voltage between the inverter terminals.

Less than 30V : High voltage circuit properly shut
More than 30V : Faulty on high voltage circuit

   
If measured more than 30V, check if the safety plug is removed completely.If measured more than 30V despite the safety plug is removed, it can be serious problems on the high voltage circuit. In this case, check DTC and never touch on the high voltage system.
