Diagnostic Steps

1
Check the tire pressures of all four tires using a reliable tire pressure gauge.
2
Inspect each tire visually for signs of damage, punctures, or foreign objects.
3
Verify if the spare tire (if equipped with a TPMS) has proper tire pressure.
4
Use an OBD-II scanner to check for any TPMS-related error codes.
5
Reset the TPMS using the vehicle's infotainment system or dedicated TPMS reset button, if applicable.

Solution

1. Preparation

Gather necessary tools including a tire pressure gauge, OBD-II scanner, and tire inflator.
Ensure the vehicle is parked on a level surface and the tires are cold for accurate pressure readings.

2. Check and Adjust Tire Pressures

Sub-steps:
1. Remove the valve caps from each tire.
2. Use the tire pressure gauge to check the pressure of each tire, including the spare.
3. Compare the readings with the manufacturer’s recommended tire pressures (usually found on the driver’s side door jamb).
4. Inflate any under-inflated tires to the recommended pressure.
5. Reattach the valve caps securely after checking.

3. Inspect Tires

Sub-steps:
1. Visually inspect each tire for visible damage, cracks, or embedded objects.
2. Check for uneven wear patterns that may indicate alignment or suspension issues.
3. If any tire is damaged, consider replacing it.

4. Reset TPMS

Sub-steps:
1. Start the vehicle and navigate to the TPMS reset option in the vehicle's infotainment system (refer to the owner's manual for specific steps).
2. Follow the prompts to reset the TPMS.
3. If a reset button is present, press and hold it until the TPMS light blinks and then turns off.
