Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine off.
Tools Required: OBD-II scanner, digital tire pressure gauge, jack and jack stands (if needed), tire iron.

2. Resetting the TPMS

Sub-steps:
1. Turn the ignition to the "ON" position without starting the engine.
2. Locate the TPMS reset button (usually found beneath the steering column or in the glove compartment).
3. Press and hold the reset button until the TPMS light blinks three times, then release it.
4. Start the engine and allow it to run for a few minutes to check if the warning light resets.

3. Replacing TPMS Sensors (if necessary)

Sub-steps:
1. If sensors are faulty, jack up the vehicle and remove the tire where the faulty sensor is located.
2. Use a tire iron to loosen and remove the wheel lug nuts.
3. Remove the tire from the rim using a tire mounting machine or manual tire levers.
4. Remove the old TPMS sensor by unscrewing the retaining nut and disconnecting the sensor from the valve stem.
5. Install the new TPMS sensor by attaching it to the valve stem and securing it with the retaining nut to the specified torque (typically around 4-5 Nm).
6. Reinstall the tire onto the rim and ensure proper bead seating.
7. Reattach the wheel to the vehicle and torque lug nuts to the manufacturer’s specifications (usually around 80-100 ft-lbs).
