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
Replacement of engine coolant temperature sensor (for Water Inlet Housing Side) Replacement of engine coolant temperature sensor (for Cylinder Head Side) Replacement of Engine coolant temperature sensor (for Outlet Side)	Inspection after repair	Poor idle, etc. Engine start function, etc.	Refer to INITIALIZATION [11/2021 - ]

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 (-) battery terminal.

Refer to INSPECTION MODE PROCEDURE [11/2021 - ]

HINT:

When the cable is disconnected / reconnected to the 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 Procedure not Performed	Necessary Procedure	Link
Lighting System (EXT)	Drive the vehicle straight ahead at 15 km/h (10 mph) or more for 1 second or more.	Refer to INITIALIZATION [11/2021 - ]
Front Camera System
Adaptive High Beam System
Stop and Start System	Idle the engine for approximately 5 to 60 minutes or drive the vehicle until stop and start control is permitted.	Refer to PRECAUTION [11/2021 - 03/2023] , or refer to PRECAUTION [03/2023 - 03/2024] , or refer to PRECAUTION [03/2024 - ]
