INSPECTION PROCEDURE

CAUTION:


  • Before inspecting the high-voltage system, take safety precautions to prevent electrical shocks, such as wearing insulated gloves and removing the service plug grip. After removing the service plug grip, put it in your pocket to prevent other technicians from accidentally reconnecting it while you are working on the high-voltage system.

  • After disconnecting the service plug grip, wait for at least 10 minutes before touching any of the high-voltage connectors or terminals.

    Tech Tips

    At least 10 minutes is required to discharge the high-voltage capacitor inside the inverter with converter assembly.

Note

After the power switch is turned off, the display and navigation module display (HDD navigation system) records various types of memory and settings. As a result, after turning the power switch off, make sure to wait for the time specified in the following table before disconnecting the cable from the negative (-) battery terminal.
