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

After performing reset memory, always perform yaw rate sensor (deceleration sensor 0 point) calibration first, and then CVT oil pressure calibration.
RESET MEMORY/CALIBRATION
Perform reset memory as follows:
Turn the ignition switch off.
Move the shift lever to P and apply the parking brake.
Connect the intelligent tester to the DLC3.
Turn the ignition switch to ON.
Note
Do not start the engine.
Turn the intelligent tester on.
Enter the following menus: Powertrain / Engine and ECT / Utility / Reset Memory.
Note
Keep the vehicle stopped, level and stable during the calibration (Inclination: 0 +/-0.25°).
Make sure that the shift lever is in P.
Make sure that the engine is stopped. To prevent idling vibrations, do not start the engine.
Make sure that the ignition switch is ON.
Perform yaw rate sensor calibration (deceleration sensor 0 point calibration) as follows:
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.
Tech Tips
When "Complete" is displayed on the screen, the deceleration sensor 0 point calibration is completed.
If "Error" is displayed on the screen and DTC P1589 is output (for the detection conditions for DTC P1589, refer to the following Click here, the yaw rate sensor circuit may have a malfunction.
Shaking or vibrating the vehicle during 0 point calibration may cancel calibration. If "Error" is displayed on the screen and DTC P1589 is not output, perform calibration again.
Perform CVT oil pressure calibration as follows:
Turn the ignition switch off and wait at least 30 seconds.
Turn the ignition switch to ON and wait at least 2 seconds.
Note
Do not start the engine.
Start the engine and wait at least 5 seconds.
Enter the following menus: Powertrain / Engine and ECT / Utility / CVT Oil Pressure Calibration.
Tech Tips
During 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.
