  1. Before the following operations are conducted, take precautions to prevent electric shock by turning the power 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 and rear hybrid motor control inverter assembly*
    • Disconnecting the low voltage connector of the HV battery
      1. *: for AWD
  2. To prevent electric shock, make sure to remove the service plug grip to cut off the high voltage circuit before servicing the vehicle.

    *a Without waiting for 10 minutes

    HINT: 

    • Waiting for at least 10 minutes is required to discharge the high-voltage capacitor inside the inverter with converter assembly rear hybrid motor control inverter assembly*.
      1. *: for AWD
NOTE:
  • After turning the power 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 PRECAUTION [10/2018 - 07/2022]

  • Before measuring the resistance of the CAN bus, turn the power switch off and leave the vehicle for 1 minute or more without operating the key or any switches, or opening or closing the doors. After that, disconnect the cable from the negative (-) auxiliary battery terminal and leave the vehicle for 1 minute or more before measuring the resistance.
  • This information describes the standard values for all CAN related components.
