⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is on a flat surface before checking tire pressure.
•Do not exceed the maximum tire pressure indicated on the tire sidewall.

Symptoms

•Warning light illuminated on the dashboard for low tire pressure
•Tire pressure monitoring system (TPMS) alert
•Uneven tire wear
•Vibration or pulling during driving

Diagnostic Steps

1
Check the tire pressure of all four tires using a tire pressure gauge.
2
Inspect tires visually for any signs of damage, such as punctures or sidewall bulges.
3
Review the vehicle's TPMS data using an OBD-II scanner to identify if there are any specific tire sensors malfunctioning.
4
Confirm that the tire pressure matches the manufacturer's recommended levels (usually found on the driver’s door jamb).
5
Reset the TPMS system using the vehicle’s onboard controls, if applicable.

Solution

1. Preparation

Gather necessary tools: tire pressure gauge, air compressor, OBD-II scanner (if needed).
Ensure the vehicle is parked on a level surface.

2. Check and Adjust Tire Pressure

Remove the valve stem caps from all tires.
Use a tire pressure gauge to measure the current pressure of each tire.
Compare the readings to the recommended pressure (found on the driver’s door jamb).
If any tire pressure is low, use an air compressor to inflate the tires to the recommended PSI.
Replace the valve stem caps securely after checking.

3. Inspect Tires

Visually inspect each tire for damages such as cuts, punctures, or excessive wear.
If any damage is found, replace the tire or repair it as necessary.

4. Reset TPMS

Turn on the ignition without starting the engine.
Navigate to the vehicle settings on the dashboard display.
Locate the TPMS reset option and follow the prompts to reset the system.
Start the vehicle and verify that the warning light has turned off.
