Solution

1. Preparation

Gather tools: OBD-II scanner, tire pressure gauge, jack and jack stands, wrench set.
Ensure vehicle is parked on a flat surface and turn off the ignition.

2. Verify Tire Pressure

Use a manual tire pressure gauge to check the pressure of each tire.
Inflate tires to the recommended pressure as indicated on the driver’s door jamb sticker.

3. Inspect and Replace TPMS Sensors (if necessary)

Remove Wheel Covers (if applicable):
- Use a flathead screwdriver to pry off wheel covers without damaging them.
Remove the Tire:
- Loosen the lug nuts with a wrench.
- Use a jack to lift the vehicle and secure with jack stands.
- Remove the lug nuts completely and take off the tire.
Inspect the TPMS Sensor:
- Locate the TPMS sensor attached to the inner wheel rim.
- Check for corrosion or damage.
Replace the TPMS Sensor:
- If necessary, remove the valve stem nut and pull out the old sensor.
- Insert a new TPMS sensor and secure with the valve stem nut to the specified torque (typically 4-5 Nm).

4. Reinstall Wheel and Reset TPMS

Place the tire back onto the wheel hub and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and tighten the lug nuts to the manufacturer’s specified torque (usually 100-110 Nm).
Reset the TPMS: Follow the vehicle’s manual to perform the reset procedure.
