⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is secured on a level surface before lifting.
•Allow tires to cool before checking pressure to avoid inaccurate readings.

Symptoms

•Tire pressure warning light illuminated on the dashboard
•Inaccurate tire pressure readings displayed on the touchscreen
•Uneven tire wear visible upon inspection
•Decreased vehicle handling or stability
•Increased road noise or vibration when driving

Diagnostic Steps

1
Check Tire Pressures: Use a tire pressure gauge to measure the pressure of each tire and compare it to the recommended pressure listed on the door jamb sticker.
2
Inspect for Damage: Visually inspect each tire for signs of punctures, cracks, or other damage that could affect pressure.
3
Examine Valve Stems: Check the valve stems for leaks or damage that could cause air loss.
4
Perform a TPMS Reset: Follow the vehicle’s manual to reset the TPMS to see if the warning clears after adjusting pressures.
5
Scan for Error Codes: Use an OBD-II scanner to check for any error codes related to the TPMS.
6
Inspect TPMS Sensors: If the problem persists, remove the tires and inspect the TPMS sensors for damage or malfunction.

Solution

1. Preparation

Tools Required: Tire pressure gauge, air compressor, socket set, OBD-II scanner, TPMS reset tool (if needed).
Ensure the vehicle is parked on a level surface and the tires are cold for accurate pressure readings.
Disconnect the battery if you need to work on any electrical components or sensors.

2. Adjust Tire Pressures

Sub-steps:
1. Remove valve caps from all tires.
2. Inflate or deflate each tire to match the recommended pressure.
3. Reinstall valve caps securely.

3. Inspect and Replace Damaged Tires

Sub-steps:
1. If any tire is damaged, remove it using a jack and tire iron.
2. Replace the tire with a new or repaired one.
3. Ensure the tire is mounted correctly and inflate to the proper pressure.

4. Reset the TPMS

Sub-steps:
1. Turn on the vehicle and navigate to the TPMS reset option on the touchscreen.
2. Follow the prompts to reset the TPMS.
3. Confirm that the warning light has extinguished.

5. Inspect TPMS Sensors

Sub-steps:
1. Remove the wheel from the hub.
2. Take out the TPMS sensor from the tire (if necessary, break the bead).
3. Inspect for corrosion or damage; replace if needed.
4. Reinstall the sensor and tire, ensuring it is properly seated.
