Tyre tronics what is

When a wheel starts spinning faster than expected, the computer calculates that the tire is underinflated and alert the driver accordingly. Instead, an indirect tire pressure monitor simply measures how fast your tires are rotating and sends signals to the computer that will actuate the indicator light when something in the rotation seems amiss.

Direct TPMS uses pressure monitoring sensors within each tire that monitor specific pressure levels — not just wheel revolution data from the anti-lock brake system. Sensors in a direct TPMS may even provide tire temperature readings. A direct tire pressure monitor usually sends all of this data wirelessly. Each sensor has a unique serial number. This is how the system not only distinguishes between itself and systems on other vehicles, but also among pressure readings for each individual tire.

Although the methods may be different, both systems serve the same purpose and activate the same indicator light. See Details Find Your Fit. Width What width? Open Chat Options.
