Diagnostic Steps

1
Verify tire pressures using a calibrated tire pressure gauge.
2
Inspect all tires for visible damage, punctures, or foreign objects.
3
Check the tire pressure monitoring system (TPMS) sensor status using an OBD-II scanner.
4

Solution

1. Preparation

Gather necessary tools: tire pressure gauge, OBD-II scanner, and a jack.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Check and Adjust Tire Pressures

Remove the valve cap from each tire.
Use the tire pressure gauge to check the pressure in all tires, including the spare.
Inflate or deflate tires to the manufacturer’s recommended pressure, typically found on the driver’s side door jamb.
Replace the valve caps securely after checking.

3. Inspect and Replace Faulty Components

If any tire is damaged or excessively worn, replace it accordingly.
If the TPMS sensors are faulty, remove the tire from the rim and replace the TPMS sensor. This requires:
- Detaching the tire from the rim using a tire machine.
- Installing the new TPMS sensor and reseating the tire on the rim.
- Balancing the wheel after reinstallation.

4. Reset the TPMS

Start the vehicle and use the OBD-II scanner to reset the TPMS, if necessary. Follow the scanner’s instructions to complete the reset cycle.
