Diagnostic Steps

1
Verify tire pressures using a tire pressure gauge to ensure they are at the manufacturer's recommended levels.
2
Inspect all tires for visible damage or punctures.
3
Check the vehicle's manual for any specific procedures related to tire pressure monitoring system (TPMS) reset.
4
Confirm that the spare tire (if equipped with a TPMS sensor) is not affecting the system.

Solution

1. Preparation

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

2. Check and Adjust Tire Pressures

Using the tire pressure gauge, check the pressure of each tire, including the spare.
Inflate or deflate the tires to match the recommended PSI, which can be found on the driver’s side door jamb label.

3. Reset the TPMS

Method 1: Through the Vehicle Settings
1. Turn the ignition to the "ON" position without starting the engine.
2. Use the infotainment system or control panel to navigate to the "Settings" menu.
3. Select "Vehicle" or "Tire Pressure" options, then choose "TPMS Reset."
4. Follow the prompts to confirm the reset.
Method 2: Manual Reset
1. If the vehicle is equipped with a TPMS reset button (usually located beneath the steering wheel or in the glove compartment), press and hold the button until the TPMS light blinks three times, then release it.
2. Start the engine and let it run for a few minutes to ensure the system recalibrates.

4. Test the System

After resetting, drive the vehicle for a short distance (approximately 10-15 minutes) at speeds above 20 mph to allow the system to update and confirm the reset.
