Start by checking the tire pressure in all four tires using a reliable tire pressure gauge, ensuring that the readings align with the manufacturer's recommended levels found in the owner's manual or on the sticker located inside the driver's side door jamb. Next, conduct a visual inspection of the tires for any signs of damage, such as punctures, cuts, or bulges, which could indicate a loss of pressure. Don’t overlook the valve stems; inspect them for any signs of wear or leaks, as faulty valve stems can lead to air loss and trigger the warning light. If these initial checks do not resolve the issue, utilize a diagnostic tool to scan for fault codes related to the tire pressure monitoring system (TPMS), which can provide insights into the specific problem. In some cases, simply resetting the TPMS may clear the warning light, so refer to your owner's manual for the reset procedure. If these steps do not yield results, it may be time to consult a professional mechanic or dealership experienced in TPMS issues for further assistance.
