The necessary procedures (adjustment, calibration, initialization, or registration) that must be performed after parts are removed and installed, or replaced during hybrid motor control inverter assembly removal/installation are shown below.

NECESSARY PROCEDURES AFTER PARTS REMOVED/INSTALLED/REPLACED

Replaced Part or Performed Procedure	Necessary Procedures	Effect/Inoperative Function when Necessary Procedure not Performed	Link
Replacement of hybrid motor control inverter assembly	ECU configuration	-	Refer to ECU CONFIGURATION [11/2022 - ]
Replacement of hybrid motor control inverter assembly	Resolver learning	DTCs are stored Slight vibration at a vehicle speed of 5 km/h (3 mph) or less Shock or vibration during acceleration	Refer to UTILITY [11/2022 - ]

WARNING:

Orange wire harnesses and connectors indicate high-voltage circuits. To prevent electric shock, always follow the procedure described in the appropriate service information .

Refer to PRECAUTION [12/2024 - ]

To prevent electric shock, wear insulated gloves when working on wire harnesses and components of the high voltage system.

HINT:

When the cable is disconnected/reconnected to the auxiliary battery terminal, systems temporarily stop operating. However, each system has a function that completes learning the first time the system is used.

Learning completes when vehicle is driven.

Effect/Inoperative Function When Necessary Procedures are not Performed	Necessary Procedures	Link
Front Camera System	Drive the vehicle straight ahead at 15 km/h (10 mph) or more for 1 second or more.	Refer to INITIALIZATION [11/2022 - ]

Learning completes when vehicle is operated normally

Effect/Inoperative Function When Necessary Procedures are not Performed	Necessary Procedures	Link
Power door lock control system Back door opener	Perform door unlock operation with door control switch or electrical key transmitter sub-assembly switch.	Refer to INITIALIZATION [11/2022 - ]
Power back door system	Fully close the back door by hand. HINT: Initialization is not necessary if the above procedures are performed while the back door is closed.	Refer to INITIALIZATION [09/2021 - ]
Air conditioning system	After the ignition switch is turned to ON, the servo motor standard position is recognized.	-
