The necessary procedures (adjustment, calibration, initialization or registration) that must be performed after parts are removed and installed, or replaced during HV battery removal/installation are shown below.
NECESSARY PROCEDURES AFTER PARTS REMOVED/INSTALLED/REPLACED
| Replaced Part or Performed Procedure | Necessary Procedure | Effect/Inoperative Function when Necessary Procedure not Performed | Link |
|---|---|---|---|
| Auxiliary battery terminal is disconnected/reconnected | Operate the multiplex network master switch assembly (retractable outer mirror switch) to extend and retract the outer rear view mirror assembly | Parking Support Brake System* | Refer to INITIALIZATION [09/2023 - ] |
| Replacement of HV battery | Battery status info update | Warning light illuminates | Refer to UTILITY [09/2023 - ] |
*: When "[Parking Support Brake System icon] System Stopped See Owner's Manual" is displayed on the multi-information display.
WARNING:
- Orange wire harnesses and connectors indicate high-voltage circuits. To prevent electric shock, always follow the procedure described in the appropriate service information
.
Refer to PRECAUTION [09/2023 - ]
- To prevent electric shock, wear insulated gloves when working on wire harnesses and components of the high voltage system.
- Tapping cannot be performed on the bolt holes shown in the illustration.
Areas where tapping is prohibited - If tapping is performed, electrical leakage, the spraying of electrolyte, and short circuits may result, leading to electrical shock or fire.
- When tapping is required, replace the HV battery with a new one.
NOTE:
- To prevent the key from being locked in the vehicle, make sure to enter e-latch inspection mode and enable the manual release handle before disconnecting the cable from the negative (-) auxiliary battery terminal.
- If the HV battery has been struck or dropped, replace it.
- When connecting a connector to the HV battery, confirm that the connector is securely connected through the following:
- Push the connector until a click sound is heard.
- Visually check and confirm that the connector is securely connected by pulling on it.
- Make sure to insulate the high-voltage connectors and terminals of the HV battery with insulating tape after removing it.
If the HV battery is stored without insulating the connectors and terminals, electric shock or fire may result.
- When performing repairs around the HV battery, such as using a tap, do not allow metal shavings to enter the HV battery.
- Do not touch any high voltage wire harnesses, connectors or parts with bare hands.
- Hold the areas shown in the illustration and lift the HV battery.
- Do not allow foreign matter, such as grease or oil, to adhere to the bolts or nuts of the HV battery.
- Do not put your hands into the openings of the HV battery.
*a Opening - When removing/installing/moving the HV battery, make sure not to tilt it more than 80°.
- Do not climb on top of or stand on the HV battery.
- Do not allow any foreign matter or water to enter the HV battery.
- If any bolts, nuts or clips are dropped into the HV battery, make sure to remove them.
