⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is on a flat surface during tire inspection and inflation.
•Always wear appropriate safety gear when handling tires and using tools.

Symptoms

•Tire pressure warning light remains illuminated on the dashboard
•Possible decrease in tire performance (handling or fuel efficiency)
•Fluctuation in tire pressure readings (if checked manually)
•Warning message on the dashboard related to tire pressure
•Vibration or noise while driving (potentially due to under-inflated tires)

Diagnostic Steps

1
Check all tire pressures manually using a reliable tire pressure gauge.
2
Inspect tires for visible signs of damage, leaks, or irregular wear.
3
Use an OBD-II scanner to check for any TPMS-related fault codes.
4
Reset the TPMS using the vehicle’s onboard menu or a TPMS reset tool (if applicable).
5
Examine the TPMS sensors for corrosion, damage, or battery issues.
6
Assess the vehicle's tire inflation status and ensure all pressures meet the manufacturer's specifications.

Solution

Solution

1. Preparation

Gather tools: tire pressure gauge, OBD-II scanner, TPMS reset tool (if applicable).
Ensure the vehicle is parked on a level surface.
Turn off the ignition and ensure all electrical components are off.

2. Check and Inflate Tires

Sub-steps:
1. Remove valve caps from each tire.
2. Use the tire pressure gauge to measure the pressure of each tire.
3. Compare the readings to the recommended PSI found on the driver's door jamb.
4. Inflate tires to the correct pressure using an air compressor.
5. Replace valve caps securely.

3. Reset the TPMS

Sub-steps:
1. Insert the key into the ignition and turn it to the "On" position (do not start the engine).
2. Navigate to the vehicle settings on the dashboard display.
3. Select the TPMS menu and choose the option to reset the system.
4. Confirm the reset and wait for the system to complete the process.

4. Inspect and Replace TPMS Sensors (if necessary)

Sub-steps:
1. Remove the tires from the rims using a tire changer (if you have access).
2. Inspect the TPMS sensors for visible damage or corrosion.
3. If damaged, replace the TPMS sensors with new units.
4. Reinstall tires, ensuring proper seating and inflation.
5. Re-calibrate the TPMS as per the manufacturer’s instructions.
