Hyundai Ioniq: Steering System / High voltage shut-off procedures
| High Voltage Shut-off Procedures |
| •
| 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 Pack Assembly, Power Relay Assembly (PRA), BMS ECU, Hybrid Power Control Unit (HPCU), Hybrid Drive Motor, HSG, Electric A/C Compressor, Low DC/DC Converter (LDC), Power Cable, Electric Compressor etc. |
|
| 1. | Turn the ignition switch OFF and disconnect the auxiliary (-) battery negative (-) terminal. |
| 2. | Remove the safety plug cover (A). 
|
| 3. | Unfasten the hook (A) and then remove the safety plug (C) by pulling the lever (B) to the direction of arrow. 
|
| 4. | Wait for more than 5 minutes so that the capacitor in the high voltage system can be fully discharged. |
| 5. | Measure the voltage between the inverter terminals to check that the capacitor in the inverter is discharged completely. | (1) | Remove air cleaner assembly and air duct. (Refer to Engine Mechanical System - "Air Cleaner") |
| (2) | Disconnect the inverter power cable (A). 
| •
| Disconnect the inverter power cable as the procedures below. |
|
|
| (3) | Measure the voltage between the inverter (+) terminal and the inverter (-) terminal. Less than 30V : More than 30V : Fault 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, there can be serious problems on the high voltage circuit. In this case, check DTC and never touch the high voltage system circuits. |
