Solution

1. Preparation

Gather necessary tools and parts before starting.
Tools Required: OBD-II scanner, tire pressure gauge, TPMS reset tool (if needed), socket set.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Check and Inflate Tires

Use a tire pressure gauge to measure the pressure in each tire.
Inflate or deflate tires to match the manufacturer's specified pressure (found on the driver’s door jamb).
Inspect tires for visible defects such as cuts or bubbles.

3. Inspect TPMS Sensors

Remove the valve caps from each tire.
Use a socket set to carefully remove the TPMS sensors if accessible.
Inspect sensors for corrosion or damage; replace if necessary.

4. Reset TPMS

Refer to the owner's manual for the specific reset procedure for the XC90 model year.
If using a TPMS reset tool, follow the manufacturer's instructions to reset the system after ensuring all tires are properly inflated.

5. Recheck System Functionality

Start the vehicle and check if the TPMS warning light has turned off.
Drive the vehicle for a short distance and recheck the tire pressure readings.
