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
Disconnect cable from negative battery terminal	Memorize steering angle neutral point	Parking assist monitor system	Refer to INITIALIZATION [12/2017 - 10/2022]
	Memorize steering angle neutral point	Panoramic view monitor system	Refer to INITIALIZATION [12/2017 - 10/2022]
	Initialize rear door sunshade system	Rear door sunshade system	Refer to INITIALIZATION [12/2017 - ]
ECM	Vehicle Identification Number (VIN) registration	DTC P063051 is output	Refer to REGISTRATION [12/2017 - ]
	Heavy Knock History Save history Write history	-	Refer to REGISTRATION [12/2017 - ]
	Perform code registration	Engine start	Refer to REGISTRATION [10/2020 - 10/2022]
	If possible to read the transmission compensation code from the previous ECM Transfer transmission compensation code (step 2)*1 Perform road test to allow ECM to learn	Large shift shock Engine overruns	for AGA0E, Initialization: Refer to INITIALIZATION [12/2017 - ] for AGA0E, Registration: Refer to REGISTRATION [12/2017 - ] for AGA0F, Initialization: Refer to INITIALIZATION [12/2017 - ] for AGA0F, Registration: Refer to REGISTRATION [12/2017 - ]
	If impossible to read the transmission compensation code from the previous ECM Set transmission compensation code (step 1)*2 Perform road test to allow ECM to learn	Large shift shock Engine overruns

*1: Read the transmission compensation code from the previous ECM, then transfer it to the new ECM.

*2: Set the transmission compensation code of the current automatic transmission.

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
