CAUTION / NOTICE / HINT
The necessary procedures (adjustment, calibration, initialization or registration) that must be performed after parts are removed, installed or replaced during the air conditioner unit assembly removal/installation are shown below.
| Replaced Part or Performed Procedure | Necessary Procedure | Effect/Inoperative Function when Necessary Procedure not Performed | Link |
|---|---|---|---|
| Disconnect cable from negative auxiliary battery terminal | Memorize steering angle neutral point | LKA/LDA system | |
| Pre-collision system | |||
| Parking assist monitor system | |||
| Steering sensor zero point calibration | Variable gear ratio steering system | ||
| Parts between the steering wheel and tires have been removed/installed, replaced or adjusted | Perform Actuator Angle Neutral Point Calibration and Initialization |

CAUTION:
Wear protective gloves. Sharp areas on the parts may injure your hands.
There is risk of injury.
CAUTION:
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.
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.
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.
CAUTION:
Some of these service operations affect the SRS airbag system. Read the precautionary notices concerning the SRS airbag system before servicing.
Tech Tips
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 |
Tech Tips
Use the same procedure for RHD and LHD vehicles.
The procedure listed below is for LHD vehicles.
PROCEDURE
PRECAUTION
Note
Make sure to perform initialization after replacing the air conditioning radiator damper servo sub-assembly. If initialization is not performed, the air conditioning unit assembly will not perform properly as the air conditioning amplifier assembly will not be able to recognize the position of the air conditioning radiator damper sub-assembly.
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.

PRECAUTION
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.
REMOVE NO. 2 DECK BOARD
DISCONNECT CABLE FROM NEGATIVE AUXILIARY BATTERY TERMINAL
CAUTION:
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.
Turn the power switch off.
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.
Check that the voltage between the terminals of the sub-battery assembly with control is 0 V.
Disconnect the cable from the negative (-) auxiliary battery terminal.
