Caution / Notice / Hint

The necessary procedures (adjustment, calibration, initialization or registration) that must be performed after parts are removed and installed, or replaced during ECM 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
Battery terminal is disconnected/reconnected	Drive the vehicle until stop and start control is permitted (approximately 5 to 60 minutes)	Stop and start system	Refer to PRECAUTION [11/2018 - 12/2021]
	Perform steering sensor zero point calibration	Lane control system	Refer to INITIALIZATION [11/2018 - 12/2021]
		Parking support brake system (for Gasoline model)*
		Pre-collision system
	Memorize steering angle neutral point	Parking assist monitor system	Refer to INITIALIZATION [11/2018 - 10/2022]
	Memorize steering angle neutral point	Panoramic view monitor system (for Gasoline model)	Refer to INITIALIZATION [11/2018 - 10/2022]
	Reset back door close position	Power back door system (for Gasoline model)	Refer to INITIALIZATION [11/2018 - 10/2023]
	Back door lock initialization	Power door lock control system	Refer to INITIALIZATION [11/2018 - ]
Replacement of ECM	Perform Vehicle Identification Number (VIN) or frame number registration	DTC P0630-51 is output	w/ Canister Pump Module: Refer to REGISTRATION [11/2018 - 08/2020] w/o Canister Pump Module: Refer to REGISTRATION [11/2018 - 08/2020]
	ECU communication ID registration	Engine start function	See Service Bulletin for the registration method.
	for UB80E: If transaxle compensation code read from ECM Perform reset memory Transfer transaxle compensation code Perform road test to allow ECM to learn	Large shift shock Deterioration of fuel efficiency	for Initialization: Refer to INITIALIZATION [11/2018 - ] for Registration: Refer to REGISTRATION [11/2018 - ]
	for UB80E: If transaxle compensation code not read from ECM Perform reset memory Reset transaxle compensation code Perform road test to allow ECM to learn	Large shift shock Deterioration of fuel efficiency
	for UB80F: If transaxle compensation code read from ECM Perform reset memory Transfer transaxle compensation code Perform road test to allow ECM to learn	Large shift shock Deterioration of fuel efficiency	for Initialization: Refer to INITIALIZATION [11/2018 - ] for Registration: Refer to REGISTRATION [11/2018 - ]
	for UB80F: If transaxle compensation code not read from ECM Perform reset memory Reset transaxle compensation code Perform road test to allow ECM to learn	Large shift shock Deterioration of fuel efficiency

*: When performing learning using the Techstream.

NOTE:

After turning the engine switch off, waiting time may be required before disconnecting the cable from the negative (-) battery terminal. Therefore, make sure to read the disconnecting the cable from the negative (-) battery terminal notices before proceeding with work.
If the ECM has been struck or dropped, replace it.
Perform Vehicle Identification Number (VIN) registration when replacing the ECM.
