Diagnostic Steps

1
Check the tire pressure of all tires, including the spare, using a tire pressure gauge.
2
Inflate any under-inflated tires to the recommended pressure as specified on the driver's side door jamb.
3
Verify that the tire pressure monitoring system (TPMS) is functioning properly by checking for any fault codes using an OBD-II scanner.

Solution

1. Preparation

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

2. Check and Adjust Tire Pressure

Use the tire pressure gauge to measure the pressure of each tire.
Inflate any tires that are below the recommended pressure to the correct PSI as indicated on the driver’s side door jamb.
After adjusting, wait a few minutes to allow the TPMS to recalibrate.

3. Reset the TPMS

Turn the ignition switch to the "ON" position without starting the engine.
Locate the TPMS reset button, usually found beneath the steering wheel or on the lower dashboard.
Press and hold the reset button until the tire pressure light blinks three times, then release it.
Start the engine and let it run for a few minutes to ensure the system resets.

4. Verify the Reset

Turn off the engine and then restart it to check if the tire pressure warning light has turned off.
If the light remains on, repeat the previous steps or consult the owner's manual for further instructions.
