Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine off before starting repairs.

2. Inspect and Replace TPMS Sensors

Remove Tires:
- Use a floor jack to lift the vehicle and secure with jack stands.
- Remove lug nuts with a socket set and take off the tire.
Access TPMS Sensor:
- If necessary, break the tire bead using a tire machine or manual tools.
- Remove the valve stem nut and take out the TPMS sensor.
Inspect Sensor:
- Check for any visible damage or corrosion on the sensor.
- If faulty, replace with a compatible TPMS sensor.
Reinstall Sensor:
- Insert the new sensor and tighten the valve stem nut to manufacturer's specifications (typically 3-5 Nm).
Reassemble Tire:
- Reinstall the tire onto the wheel, ensuring it is properly seated.
- Inflate the tire to the recommended pressure and reattach it to the vehicle.

3. Reset TPMS System

Turn on Ignition:
- Insert the key and turn the ignition to the "ON" position without starting the engine.
Use TPMS Reset Tool:
- If equipped, use a TPMS reset tool to initiate a reset according to the tool's instructions.
- Alternatively, follow the owner’s manual procedure, which may involve pressing the TPMS reset button located under the steering column.
Test Drive:
- Drive the vehicle for a short distance (10-15 minutes) to allow the system to recalibrate and check if the light turns off.
