Initialization [08/2013 - 08/2016]

WARNING: This page is about a different car, the 2018 Toyota Corolla, 2017 Toyota Corolla, 2016 Toyota Corolla, 2015 Toyota Corolla, and 2014 Toyota Corolla. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

Performing Reset Memory will clear the learned value of the yaw rate and acceleration sensor (deceleration sensor zero point calibration) and the CVT oil pressure (CVT oil pressure calibration). Make sure to perform Reset Memory, yaw rate and acceleration sensor zero point calibration, and CVT oil pressure calibration when replacing any of the parts shown in the following table.

Replaced Part
Continuously variable transaxle assembly ECM Oil pressure sensor Airbag sensor assembly (Yaw rate and acceleration sensor)

After performing Reset Memory, always perform yaw rate and acceleration sensor (deceleration sensor zero 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 Techstream to the DLC3.
Turn the ignition switch to ON.
NOTE:
Do not start the engine.
Turn the Techstream on.

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

NOTE:

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. To prevent idling vibrations, do not start the engine.
Make sure that the ignition switch is ON.

Perform deceleration sensor zero 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 Zero Point Calibration.

HINT:

When "Complete" is displayed on the screen, deceleration sensor zero point calibration is complete.
If "Error" is displayed on the screen and DTC P1589 is output (for the detection conditions for DTC P1589), refer to P1589, the deceleration sensor circuit may be malfunctioning.
Refer to DTC P1589: Acceleration Sensor Learning Value [08/2013 - ]
Shaking or vibrating the vehicle during deceleration sensor zero 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.

HINT:

CVT oil pressure calibration is performed with the ignition switch ON (engine stopped). However, the calibration cannot be performed under the following conditions:
- Oil pressure sensor value is 0.065 MPa (0.663 kgf/cm² , 9.43 psi) or more.
- CVT oil temperature is 0°C (32°F) or less or 120°C (248°F) or more.
Start the engine and wait at least 5 seconds.

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

HINT:

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