Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and the engine is turned off.
Safety warning: Disconnect the battery before working on electrical components.

2. Inspect and Replace TPMS Sensors

Tools Required: Tire iron, TPMS sensor tool, torque wrench, OBD-II scanner.
Remove the wheel covers or hubcaps if applicable.
Loosen and remove the lug nuts using a tire iron and then take off the wheel.
Use the TPMS sensor tool to check the functionality of each sensor; replace any that are faulty.
- Sub-steps:
  - If a sensor needs replacement, remove the old sensor by unscrewing it from the valve stem.
  - Install a new TPMS sensor, ensuring it is securely fastened.
  - Reinstall the wheel and torque the lug nuts to the manufacturer’s specifications (usually around 100-150 ft-lbs depending on model).
Repeat for each wheel as necessary.

3. Reset TPMS

Reconnect the battery if disconnected.
Turn the ignition to the "ON" position without starting the engine.
Use the OBD-II scanner to reset the TPMS system or follow the vehicle-specific reset procedure found in the owner's manual.
Drive the vehicle for at least 10 minutes to allow the system to recalibrate.
