Caution / Notice / Hint

The necessary procedures (adjustment, calibration, initialization or registration) that must be performed after parts are removed and installed, or replaced during engine coolant temperature sensor removal/installation are shown below.

NECESSARY PROCEDURES AFTER PARTS REMOVED/INSTALLED/REPLACED

Replaced Part or Performed Procedure	Necessary Procedure	Effect/Inoperative Function when Necessary Procedure not Performed	Link
Auxiliary battery terminal is disconnected/reconnected	Operate the multiplex network master switch assembly (retractable outer mirror switch) to extend and retract the outer rear view mirror assembly	Parking Support Brake System*	Refer to INITIALIZATION [10/2022 - ]
Replacement of ECM	Perform Vehicle Identification Number (VIN) registration	DTC is output	Refer to REGISTRATION [10/2022 - ]
	ECU configuration	-	Refer to ECU CONFIGURATION [10/2022 - ]
	Update ECU security key	Vehicle Control History (RoB) are stored	Refer to UPDATE ECU SECURITY KEY [10/2022 - ]
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	for THS-HEV Model: Refer to UTILITY [10/2022 - ] for PHEV Model: Refer to UTILITY [08/2023 - ]
for PHEV Model: Service plug grip	High voltage fuse accumulated load history reset	DTCs are stored	Refer to UTILITY [08/2023 - ]
Replacement of engine coolant temperature sensor	Inspection after repair	Poor idle, etc. Engine start function, etc.	Refer to INITIALIZATION [10/2022 - ]

*: When "[Parking Support Brake System icon] System Stopped See Owner's Manual" is displayed on the multi-information display.

NOTE:

To prevent the key from being locked in the vehicle, make sure to enter e-latch inspection mode and enable the manual release handle before disconnecting the cable from the negative (-) auxiliary battery terminal.

Refer to INSPECTION MODE PROCEDURE [10/2022 - ]

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.
