K41B CVT: CONTINUOUSLY VARIABLE TRANSAXLE SYSTEM: INITIALIZATION

NOTICE:
* Performing reset memory/initialization will clear the learned values of both the yaw rate and acceleration sensor (deceleration sensor 0 point calibration) and the CVT oil pressure (CVT oil pressure calibration). Make sure to perform reset memory, yaw rate and acceleration sensor 0 point calibration, and CVT oil pressure calibration when replacing any of the parts shown in the following table:






* After reset memory, always perform yaw rate and acceleration sensor (deceleration sensor 0 point) calibration first, and then the CVT oil pressure calibration.

1. RESET MEMORY

(a) Perform the reset memory as follows:

(1) Turn the ignition switch off.

(2) Move the shift lever to P and apply the parking brake.

(3) Connect the Techstream to the DLC3.

(4) Turn the ignition switch to ON.

NOTICE:
Do not start the engine.

(5) Turn the Techstream on.

(6) Perform the Reset Memory procedure from the main menu.

(7) Enter the following menus: Powertrain / Engine and ECT / Utility / Reset Memory.

(8) Press "Next".

(b) Deceleration Sensor 0 Point Calibration

NOTICE:
* Keep the vehicle stopped, level and stable during the calibration.
* Make sure that the shift lever is in P.
* Make sure that the engine is stopped.
* Make sure that the ignition switch is ON.
* To prevent idling vibrations, do not start the engine.

(1) Perform the yaw rate and acceleration sensor (deceleration sensor 0 point calibration) as follows:

(1) Turn the ignition switch to ON and wait at least 2 seconds.

Enter the following menus: Powertrain / Engine and ECT / Utility / Deceleration Sensor 0 Point Calibration.*1

Press "Next".*2

HINT
* When "Complete" is displayed on the screen, the deceleration sensor 0 point calibration is completed.
* If "Error" is displayed on the screen, the deceleration sensor circuit may have a malfunction.
* Shaking or vibrating the vehicle during the 0 point calibration may cancel the calibration. If "Error" is displayed on the screen, perform steps *1 and *2 again.

(c) CVT Oil Pressure Calibration

(1) Turn the ignition switch off and wait at least 30 seconds.

(2) Turn the ignition switch to ON and wait at least 2 seconds.

NOTICE:
Do not start the engine.

(3) Start the engine and wait at least 5 seconds.

(4) Enter the following menus: Powertrain / Engine and ECT / Utility / CVT Oil Pressure Calibration.

(5) Press "Next".

HINT
* During the CVT oil pressure calibration, the engine idle speed will increase.
* When "Complete" is displayed on the screen, the CVT oil pressure calibration is completed.
* The learned values cannot be cleared by only disconnecting and reconnecting the cable to the negative (-) battery terminal.
