⚠️ Safety Warnings

Important safety information - read before proceeding

•Always ensure the vehicle is securely lifted on jack stands before working under it.
•Allow tires to cool before checking pressure, as heat can affect readings.

Symptoms

•Warning light illuminated on the dashboard
•Tire pressure readings below recommended levels
•Uneven tire wear
•Vehicle handling issues (e.g., pulling to one side)
•Reduced fuel efficiency
•Possible warning message on the multi-information display

Diagnostic Steps

1
Check the tire pressure of all tires using a tire pressure gauge.
2
Inspect tires visually for signs of damage, punctures, or foreign objects.
3
Verify the TPMS status using an OBD-II scanner for any error codes related to tire pressure.
4
Examine the TPMS sensors for proper functionality and battery life (if applicable).
5
Inspect the valve stems for leaks or damage.
6
Reset the TPMS system to see if the light remains illuminated after corrections.

2. Check and Adjust Tire Pressure

Sub-steps:
1. Remove the valve cap from each tire.
2. Use a tire pressure gauge to check the pressure on each tire.
3. Inflate tires to the recommended pressure using an air compressor.
4. Replace the valve caps securely.

Tools Required: Tire pressure gauge, air compressor

3. Inspect Tires for Damage

Sub-steps:
1. Visually inspect each tire for cuts, punctures, or signs of wear.
2. If damage is found, remove the tire and inspect the inner liner.
3. Repair or replace damaged tires as necessary.

Tools Required: Tire jack, lug wrench, tire repair kit or replacement tire

4. Examine TPMS Sensors

Sub-steps:
1. Remove the tire from the wheel to access the TPMS sensor (if necessary).
