⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is securely supported on jack stands before working on tires.
•Wear safety gloves and goggles when handling tires.

Symptoms

•Tire pressure warning light illuminated on the dashboard
•Abnormal tire wear patterns
•Tire deflation or visible bulges
•Fluctuations in tire pressure readings
•Difficulty maintaining tire pressure

Diagnostic Steps

1
Inspect all tires visually for any signs of damage, such as punctures or bulges.
2
Use a tire pressure gauge to measure the pressure in all four tires and compare with the manufacturer's recommended pressures.
3
Check the spare tire (if applicable) for proper inflation.
4
Scan the vehicle’s onboard diagnostic system with an OBD-II scanner for any related error codes.
5
Reset the tire pressure monitoring system (TPMS) to see if the light reappears.
6
Inspect the TPMS sensors for any signs of malfunction or corrosion.

Solution

Solution

1. Preparation

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

2. Tire Inspection

Sub-steps:
1. Remove the valve caps from each tire.
2. Use the tire pressure gauge to check the pressure in each tire.
3. Inspect each tire for visible damage (punctures, cracks, or bulges).
4. If any damage is found, mark the tire for replacement.

3. Adjust Tire Pressure

Sub-steps:
1. Inflate or deflate each tire to match the manufacturer's recommended pressure, typically found on the driver's door jamb.
2. Reinstall the valve caps securely.

4. TPMS Sensor Check

Sub-steps:
1. If tire pressure is correct and the warning light remains, use the OBD-II scanner to check for TPMS-related error codes.
2. If codes indicate a malfunctioning sensor, proceed to replace the affected TPMS sensor(s).
3. After replacing, reset the TPMS using the vehicle's reset procedure, usually found in the owner's manual.

5. Final Inspection

Sub-steps:
1. Ensure all tires are properly inflated and that any damaged tires have been addressed.
2. Double-check that the TPMS reset has been accepted by the vehicle.
