Solution

1. Preparation

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

2. Check and Adjust Tire Pressure

Sub-step 1: Use a tire pressure gauge to measure the pressure in each tire.
Sub-step 2: Compare the measured pressure to the recommended pressure (found on the driver’s door jamb).
Sub-step 3: Inflate or deflate the tires as necessary to reach the correct pressure.

3. Reset Tire Pressure Monitoring System (TPMS)

Sub-step 1: Insert the key fob into the ignition and turn it to the "On" position without starting the engine.
Sub-step 2: Locate the TPMS reset button (typically found under the steering column or in the glove box).
Sub-step 3: Press and hold the TPMS reset button until the tire pressure warning light blinks three times, then release it.
Sub-step 4: Turn off the ignition and start the engine. The light should turn off after a few moments.

4. Verify System Functionality

Sub-step 1: Drive the vehicle for a short distance (approximately 10 minutes) to allow the system to recalibrate.
Sub-step 2: If the warning light remains on, repeat the reset procedure or check for faults in the TPMS.
