Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is turned off.
Gather safety equipment like gloves and glasses.

2. Check and Inflate Tires

Tools Required: Tire pressure gauge, air compressor
Use the tire pressure gauge to measure the pressure of each tire.
Refer to the vehicle's placard for the correct tire pressure specifications.
If any tire is below the recommended pressure, inflate it using an air compressor to the appropriate level.

3. Inspect and Replace Damaged Tires

Tools Required: Tire iron, jack, jack stands
If any tire shows signs of damage, remove it using a tire iron and jack the vehicle safely.
Inspect the inner and outer sidewalls for punctures or significant wear.
If damaged, replace the tire with a new one ensuring it matches the specifications of the original.

4. Check and Replace Valve Stems (if necessary)

Tools Required: Tire iron, jack, valve stem tool
If a valve stem is leaking, remove the tire from the rim using the tire iron and jack.
Replace the faulty valve stem using a valve stem tool.
Reinstall the tire and ensure it is properly secured.

5. Reset TPMS

Navigate to the vehicle’s touchscreen settings.
Locate the TPMS reset option and follow the prompts to reset the system.
Confirm the reset is successful and monitor for any error messages.
