This procedure relearns the TPMS sensor positions after tire rotation, sensor replacement, or loss of TPMS data on 2014-2019 Toyota Corolla vehicles.

Warnings

Tools required

Preparation

1. Park vehicle on level ground and engage parking brake
2. Turn ignition off and ensure all doors are closed
3. Verify all four TPMS sensors are installed and functional
4. Check and adjust all tire pressures to door jamb placard specification (typically 32-35 PSI front and rear)
5. Ensure TPMS warning light is illuminated on dash (indicating system needs relearn)

Procedure

1. 1

   Access TPMS relearn mode
   Turn ignition to ON position without starting engine. Locate the TPMS reset button under the steering column near the hood release lever. Press and hold the TPMS reset button until the TPMS warning light blinks three times slowly, then release. The light will remain on during relearn process.
2. 2

   Relearn left front sensor
   Starting with the left front tire, use TPMS relearn tool to activate the sensor by holding tool against sidewall near valve stem. Alternatively, reduce tire pressure by 5-10 PSI then re-inflate to specification to trigger sensor. Wait for horn chirp or dash light confirmation before proceeding.
3. 3

   Relearn right front sensor
   Move to right front tire and repeat activation process. Use TPMS tool or pressure change method. Wait for horn chirp or confirmation signal before continuing to next wheel.
4. 4

   Relearn right rear sensor
   Move to right rear tire and activate sensor using same method as previous wheels. Proceed in clockwise pattern as viewed from above vehicle. Wait for confirmation signal.
5. 5

   Relearn left rear sensor
   Complete relearn sequence at left rear tire. Activate sensor and wait for final confirmation signal. After this wheel, system should complete relearn process automatically.
6. 6

   Complete relearn process
   Turn ignition off then restart engine. TPMS warning light should illuminate for approximately 3 seconds then turn off. If light remains on or blinks, relearn was unsuccessful and procedure must be repeated.
7. 7

   Verify tire pressures
   Using tire pressure gauge, verify all four tires are at correct pressure per door jamb placard. Adjust as necessary. Drive vehicle for 5-10 minutes above 25 MPH to allow system to fully initialize.

Reassembly

1. No disassembly required for this procedure

Verification

• TPMS warning light should remain off after engine start and during driving
• If equipped with multi-information display, verify individual tire pressures are displayed correctly for each wheel position
• Test system by reducing pressure in one tire by 5 PSI - warning light should illuminate within 1-2 minutes of driving
• Re-inflate test tire to specification and verify light turns off after brief drive
