CAUTION / NOTICE / HINT

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 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.

    Click here

    Tip:

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

  • When disposing of an HV battery, make sure to return it through an authorized collection agent who is capable of handling it safely. If the HV battery is returned via the manufacturer specified route, it will be returned properly and in a safe manner by an authorized collection agent.

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.

Tip:

  • If DTC P0A9C-123, P0AC6-123, P0ACB-123, P0AE9-123, P0BC3-123 or P0C34-123 is output, clear the DTCs, perform the following procedure, and check that the same DTC (including pending DTC) is not output after the repair.

    1. Drive the vehicle for approximately 10 minutes according to the freeze frame data items "Vehicle Spd", "Accelerator Degree", "Temp of Batt TB1 to 6" and "Power Resource IB".

      1. Check that the difference in output between each battery temperature sensor is not excessively large.

      2. Check that the output of each battery temperature sensor varies.

  • If DTC P3065-123 or P306A-123 is output, clear the DTCs, perform the following procedure, and check that the same DTC is not output after the repair.

    1. Turn the power switch on (IG) and wait for 10 seconds or more.

      • Check that the difference in output between each battery temperature sensor is not excessively large.
