K121 CVT  VALVE BODY ASSEMBLY  REMOVAL  

The necessary procedures (adjustment, calibration, initialization, or registration) that must be performed after parts are removed, installed, or replaced during the transmission valve body assembly removal/installation are shown below.

Necessary Procedure After Parts Removed/Installed/Replaced

Replacement Part or Procedure	Necessary Procedure	Effect/Inoperative when not Performed	Link
Transmission valve body assembly	· Reset transaxle compensation code · Perform reset memory · Deceleration sensor zero point calibration · CVT oil pressure calibration · Perform road test to allow ECM to learn	· Large shift shock · Deterioration of fuel efficiency	for Initialization: (202409,999999,_52,_138176,_0584691,RM100000002NRHB,) for Registration: (202304,999999,_52,_138176,_0584691,RM1000000029HF6,)
CVT fluid	ATF thermal degradation estimate reset	The value of the Data List item "ATF Thermal Degradation Estimate" is not estimated correctly	(202409,999999,_52,_138176,_0584691,RM100000002NRHB,)
	Air bleed oil pump with motor assembly	Stop and start system	(202409,999999,_51,_083056,_0402418,RM100000002NSFT,)

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.

*: w/ Power back door system
Power back door function*	Fully close the back door by hand. HINT: Initialization is not necessary if the above procedures are performed while the back door is closed.	(202304,999999,_59,_083093,_0584672,RM1000000029PGT,)
Power door lock control system	If the back door is locked and therefore cannot be opened, it is necessary to unlock the back door using the door control switch, electrical key transmitter sub-assembly switch.	(202409,999999,_58,_083092,_0403003,RM100000002NS90,)
Air conditioning system	After the ignition switch is turned to ON, the servo motor standard position is recognized	-

Shift shock may increase after replacing the transmission valve body assembly. In this case, shift shock will reduce as the vehicle in driven.
