CAUTION:


  • B004YIH

    This vehicle has contains high voltage circuits standardized with orange colored wiring and connectors, so follow the instructions in this manual to perform the procedures correctly.

    Click here

  • If the correct procedures are not followed according to the instructions in this manual, there is a danger of electric shock from the high voltage circuits.

  • B004STG

    Be sure to wear insulating gloves when working on high voltage wiring or components.

  • If work is performed without wearing insulating gloves, there is a danger of electric shock.

Tech Tips


  • Use the same procedure for RHD and LHD vehicles.

  • The procedure listed below is for LHD vehicles.

  • When removing the air conditioner radiator damper servo sub-assembly, reinstallation is easier to perform if the following conditions are set before disconnecting the negative (-) auxiliary battery terminal.

    Item Condition
    Air vent damper position Face
    Set temperature Max cool

PROCEDURE


  1. PRECAUTION

    Note


    • Perform these service operations when removing and installing the instrument panel reinforcement assembly.

    • The No. 1 instrument panel spacer installed to the instrument panel reinforcement assembly and vehicle is equipped with an automatic adjustment function that closes the gap between the instrument panel reinforcement assembly and vehicle when the installation bolt is tightened. However, when the instrument panel reinforcement assembly is removed and installed, this function may be lost, so make sure to replace the No. 1 instrument panel spacer with a new one.

    • If it is necessary to replace the instrument panel extension spacer, use a new one of the same color as that which was removed.

  2. AIR SUSPENSION CONTROL PROHIBITED (w/ Air Suspension)

  3. CHECK FOR DTC

    CAUTION:


    • Confirm that DTC P0AA649 (Hybrid/EV Battery Voltage System Isolation Internal Electronic Failure), P1C7C49 (Hybrid/EV Battery Voltage System Isolation (A/C Area) Internal Electronic Failure), P1C7D49 (Hybrid/EV Battery Voltage System Isolation (Hybrid/EV Battery Area) Internal Electronic Failure), P1C7E49 (Hybrid/EV Battery Voltage System Isolation (Transaxle Area) Internal Electronic Failure) or P1C7F49 (Hybrid/EV Battery Voltage System Isolation (Direct Current Area) Internal Electronic Failure) is not output before removing or installing the HV battery assembly. If this DTC is output, perform troubleshooting for this DTC first.

    • To reduce the risk of electric shock, do not perform troubleshooting before checking for DTCs.

    CAUTION:


    • B004UM0

      Wait at least 90 seconds after disconnecting the cable from the negative (-) auxiliary battery terminal to disable the SRS system.

    • If the airbag deploys for any reason, it may cause a serious accident.

    Note

    It is necessary to remove the shift control ECU while no power is being supplied from the sub-battery. Therefore, perform the following procedures.


    1. Turn the power switch off.

    2. Check that the ODO meter display has turned off.

      Tech Tips

      The ODO meter continues to display for 30 seconds after turning off. Therefore, allow sufficient time for the shift control ECU to enter sleep mode and for the sub-battery power supply to end. In addition to monitoring the sub-battery voltage directly, the only other method for checking on the vehicle is to use the ODO meter display.
