•Ensure the vehicle is on a stable surface while performing tire work.
•Wear safety glasses and gloves when handling tires and tools.

Symptoms

•Low tire pressure warning light illuminated on the dashboard
•Possible visual inspection reveals a flat or visibly low tire
•Tire pressure gauge shows readings below the manufacturer's recommended PSI
•Increased road noise or vibration while driving
•Vehicle handling feels unstable or less responsive

Diagnostic Steps

1
Check the tire pressure of all four tires using a tire pressure gauge.
2
Inspect each tire visually for signs of damage, punctures, or leaks.
3
Verify the TPMS system functionality using the vehicle’s onboard diagnostic interface.
4
Check for any stored error codes related to TPMS using an OBD-II scanner.

Solution

1. Preparation

Tools Required: Tire pressure gauge, air compressor, OBD-II scanner, tire repair kit (if needed)
Ensure the vehicle is parked on a level surface and the tires are cold for accurate pressure readings.

2. Inflate Tires

Sub-steps:
1. Use the tire pressure gauge to check the current PSI of each tire.
2. If any tire is found to be below the recommended PSI, connect the air compressor.
3. Inflate the tire to the specified PSI as indicated on the driver’s door jamb or in the vehicle manual.
4. Re-check the tire pressure with the gauge after inflation to ensure it meets the recommended level.

3. Inspect and Replace Damaged Tires

Sub-steps:
1. If a tire shows visible damage or a puncture, remove it from the vehicle.
2. If the tire is repairable, follow standard procedures to patch the puncture. If not, replace with a new tire.
3. Ensure the replacement tire matches the specifications of the other tires (size, type, and brand).

4. Reset TPMS

Sub-steps:
1. After addressing tire pressure and any repairs, reset the TPMS using the vehicle’s onboard settings.
2. Navigate to the settings menu and select the TPMS reset option to recalibrate the system.
3. Confirm that the low tire pressure warning light has turned off.
