Solution

1. Preparation

Gather the necessary tools and parts, such as a TPMS tool, OBD-II scanner, and a tire pressure gauge.
Ensure the vehicle is parked on a flat surface and the engine is off.

2. Replace Faulty TPMS Sensors

Sub-steps:
1. Remove the tire from the wheel using a jack and tire changing tools.
2. Use a TPMS tool to deactivate the faulty sensor.
3. Unscrew the valve stem nut and remove the defective TPMS sensor from the wheel.
4. Install the new TPMS sensor by securing it to the valve stem and tightening the nut to the manufacturer's specifications.
5. Reinstall the tire onto the wheel and ensure it is properly balanced.

3. Reset the TPMS System

Sub-steps:
1. Turn the ignition to the "On" position without starting the engine.
2. Use the OBD-II scanner to reset the TPMS system.
3. Alternatively, navigate to the settings menu on the vehicle's display and select the option to reset the TPMS.
4. Drive the vehicle for a few minutes to allow the system to recalibrate.

4. Inspect and Repair Wiring

Sub-steps:
1. Locate the TPMS control module and inspect the wiring harness for any damage.
2. Clean any corroded connectors with electrical contact cleaner.
3. Repair or replace any damaged wiring as necessary.

5. Final Checks

Sub-steps:
1. Recheck tire pressures to ensure they are at the recommended levels.
2. Monitor the TPMS warning light to confirm it remains off during test drives.
