Caution / Notice / Hint
- Before the following operations are conducted, take precautions to prevent electric shock by turning the ignition switch off, wearing insulated gloves, and removing the service plug grip from HV battery.
- Inspecting the high-voltage system
- Disconnecting the low voltage connector of the inverter with converter assembly
- Disconnecting the low voltage connector of the HV battery
- Disconnecting the low voltage connector of the voltage inverter assembly (w/ 1500W voltage inverter)
- To prevent electric shock, make sure to remove the service plug grip to cut off the high voltage circuit before servicing the vehicle.
- After removing the service plug grip from the HV battery, put it in your pocket to prevent other technicians from accidentally reconnecting it while you are working on the high-voltage system.
- After removing the service plug grip, wait for at least 10 minutes before touching any of the high-voltage connectors or terminals. After waiting for 10 minutes, check the voltage at the terminals in the inspection point in the inverter with converter assembly. The voltage should be 0 V before beginning work.
Refer to PRECAUTION [12/2019 - 10/2022] , or refer to PRECAUTION [10/2022 - 11/2023]
HINT:
Waiting for at least 10 minutes is required to discharge the high-voltage capacitor inside the inverter with converter assembly.
*a Without waiting for 10 minutes
After turning the ignition switch off, waiting time may be required before disconnecting the cable from the negative (-) auxiliary battery terminal. Therefore, make sure to read the disconnecting the cable from the negative (-) auxiliary battery terminal notices before proceeding with work.
Refer to INITIALIZATION [12/2019 - 09/2020] , or refer to INITIALIZATION [09/2020 - 10/2021] , or refer to INITIALIZATION [10/2021 - 10/2022] , or refer to INITIALIZATION [10/2022 - 11/2023]
HINT:
If the NODD signal line is open, DC/DC converter control will be prohibited and the auxiliary battery voltage will be approximately 12 V or less.
