Solution

1. Preparation

Gather the necessary tools and parts.
Ensure the vehicle is on a flat surface and the engine is turned off.
Wear safety gloves and goggles.

2. Inspect and Reset TPMS

Sub-steps:
- Locate the TPMS reset button, which is usually found under the steering column or in the glove compartment.
- Turn the ignition to the "On" position without starting the engine.
- Press and hold the TPMS reset button until the TPMS light blinks three times, then release it.
- Start the engine and drive the vehicle for at least 10 minutes to allow the system to recalibrate.

3. Replace Faulty TPMS Sensors

Tools Required: Tire iron, jack, TPMS sensor tool (if needed)
Sub-steps:
- Loosen wheel lug nuts with a tire iron.
- Lift the vehicle using a jack and securely place jack stands underneath.
- Remove the wheel and inspect the TPMS sensor.
- If damaged, replace the sensor by unscrewing it from the valve stem.
- Install the new sensor and secure it properly.
- Reattach the wheel, tighten the lug nuts to the manufacturer's specified torque, and lower the vehicle.

4. Update TPMS Software

Sub-steps:
- Connect the OBD-II scanner to the vehicle’s diagnostic port.
- Check for available software updates for the TPMS system.
- Follow the scanner’s prompts to install any available updates.
- Clear any error codes and reset the TPMS if necessary.
