Solution

1. Preparation

Gather necessary tools: tire pressure gauge, OBD-II scanner, and any required replacement parts.
Ensure the vehicle is parked on a level surface and the tires are cool.

2. Check and Adjust Tire Pressure

Remove the valve caps from each tire.
Use the tire pressure gauge to measure the current tire pressure.
Inflate or deflate each tire to match the recommended pressure specified on the driver's side door jamb.
- Tools Required: Tire inflator or compressor, tire pressure gauge

3. Inspect and Repair Tires

Visually examine each tire for cuts, punctures, or bulges.
If a puncture is found, use a tire plug kit to seal small punctures or replace the tire if damage is extensive.
- Tools Required: Tire plug kit, jack, jack stands, lug wrench

4. Replace TPMS Sensor (if necessary)

If the TPMS sensor is faulty:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the tire from the wheel using a lug wrench.
3. Detach the old TPMS sensor from the tire and replace it with a new one.
4. Reassemble the tire onto the wheel and tighten the lug nuts to the manufacturer's torque specifications.
5. Repeat for each affected tire.
- Tools Required: Torque wrench, socket set

5. Reset the TPMS

After repairs, navigate to the vehicle settings on the touchscreen.
Select the option to reset or calibrate the TPMS.
Drive the vehicle for a short distance to allow the system to recalibrate.
