Caution / Notice / Hint
WARNING:
- 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 hybrid motor control inverter assembly
- Disconnecting the low voltage connector of the HV battery
- Disconnecting the low voltage connector of the electric vehicle charger assembly
- Disconnecting the low voltage connector of the voltage inverter assembly
- 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 hybrid motor control inverter assembly. The voltage should be 0 V before beginning work.

- Before returning the HV battery, make sure to perform a recovery inspection.
Refer to RECOVERY INSPECTION [06/2020 - ]
- Before returning the HV supply stack sub-assembly, make sure to perform a recovery inspection.
Refer to RECOVERY INSPECTION [06/2020 - ]
- Make a note of the output DTCs as some of them may be necessary for recovery inspection of the HV battery and HV supply stack sub-assemblies.
- After removing the HV battery, keep it away from water. Exposure to water may cause the HV battery to produce heat, resulting in a fire.
NOTE:
- If "Maintenance Required for Traction Battery at Your Dealer" is displayed on the multi-information display, the message will not be cleared until one of the following conditions is met. If the traction battery is used continually without performing "Battery Diagnosis" for a few weeks*, "VEHICLE START WILL SOON BE DISABLED" and "Maintenance Required for Traction Battery at Your Dealer" are displayed and the use of the HV battery is limited. If it is used more, the ignition switch ON (READY) operation will be disabled.
*: Timing may vary depending on vehicle usage.
- Perform plug-in charging several times as specified.
- After the ignition switch is turned off, there may be a waiting time before disconnecting the auxiliary negative (-) battery terminal.
- When disconnecting and reconnecting the auxiliary battery.
