Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the tires are cool.
Disconnect the battery to avoid any electrical issues during repairs.

2. Inspect and Replace TPMS Sensors

Tools Required: Tire pressure gauge, OBD-II scanner, socket set, torque wrench.
Sub-steps:
1. Remove the wheel covers or hubcaps if applicable.
2. Loosen the lug nuts and lift the vehicle using a jack. Support it securely with jack stands.
3. Remove the wheel to access the TPMS sensor.
4. Use a torque wrench to remove the TPMS sensor from the valve stem.
5. Inspect the sensor for damage. If damaged, replace it with a new TPMS sensor.
6. Reinstall the sensor and tighten to the manufacturer’s specifications (typically around 3-5 Nm).
7. Reattach the wheel and lower the vehicle back to the ground.

3. Reset the TPMS System

Tools Required: OBD-II scanner (if required for reset).
Sub-steps:
1. Turn the ignition to the "ON" position without starting the engine.
2. Use the vehicle's menu to navigate to the TPMS reset option or consult the owner's manual for specific instructions.
3. If the vehicle requires a scanner, connect the OBD-II scanner and follow the prompts to reset the TPMS.
4. Confirm that the reset was successful by checking for the TPMS warning light on the dashboard.
