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 (-) 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.

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

    B006BY6

    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 engine 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.
