What is TPMS?

What Is A Tire Pressure Monitoring System?

A tire pressure monitoring system or TPMS is an electronic system for monitoring the air pressure in a vehicle tire and automatically transmitting a warning to the driver in the event of an under or over inflated tire. These systems have been legislated to be progressively installed on all new passenger carrying US vehicles and a similar move is taking place worldwide.

The majority of systems use Direct tire sensors which transmit real time tire pressure information to the driver of the vehicle either via either a dashboard display or a warning light. The sensors are physical pressure transducers which are attached to the back of the valve stem or are in a form which is banded to the wheel. The sensors are manufactured by International companies such as Schrader, Siemens, TRW, Pacific, Lear and others. There is no common technical standard for the sensors and the OE's and suppliers have generated a multitude of sensor designs.

The sensors also transmit data such as their unique sensor ID, temperature and pressure, battery life and other diagnostic information. This data is sent to the Engine Control Unit (ECU) or specific receiver on the vehicle. Those vehicles which have graphical displays of the TPMS positions can then show on which wheel there is a problem.

Why is there a need for Tire Pressure Monitoring?

Tire Pressure Monitoring helps drivers to properly maintain their vehicle tires, improves vehicle safety and aid fuel efficiency. The National Highway Traffic Safety Administration (NHTSA) in the US has estimated that 533 fatalities per annum are caused by tire defects in road accidents. Adding TPMS to all vehicles could avoid 120 of the 533 yearly victims and save as many as 8,400 injuries every year. Sécurité Routière (the French Institution for Road Safety) estimates that 9% of all fatal road accidents are attributable to tire under-inflation and the German DEKRA estimated that 41% of accidents with physical injuries are linked to tire problems. Tires leak air naturally and over a year a typical new tire can lose between 3 and 9 psi. As most drivers only check their tires at service intervals and when problems occur there is significant scope for fuel savings and efficiencies.

Given this background the US Federal government has legislated for the mandatory use of TPMS. The TPMS mandated by the US law must warn the driver when a tire is under-inflated by as much as 25%.

What is a Tire Pressure Monitoring Tool?

There is no common standard for the TPMS sensors with variations including frequencies, modulations, data structure, communications protocols, mechanical fitment and many other factors.

When TPMS is installed and tested in the car plant by Bartec the process includes:

• The TPMS sensors are attached to the wheel during the Wheel and Tire assembly process
• The wheels are attached to the vehicle. This is the first time at which the TPMS can be clearly associated with the vehicle
• Fixed radio antennas are used to extract the unique IDs (and other data) of the TPMS, associate them with their wheel position on the car and the Engine Control Unit (ECU) can then be programmed with this data
• The car is then run through Rolls Test where the system is tested

Similarly the car dealer or tire shop needs to have a portable TPMS tool available to test the TPMS and read the wheel sensor ID and program the car's ECU in the event of TPMS battery failure, broken sensor/valve, or other repair or replacement of wheels and sensors for custom wheels, winter tires, tire rotation etc. The tool needs to be able to turn out the TPMS warning light.

Tires are crucial components of a car, and tire pressure plays a vital role in their performance. Whether too low or too high, tire pressure can significantly impact tire performance and driving safety.

TPMS, or Tire Pressure Monitoring System, continuously monitors tire pressure while driving, providing real-time alerts for air leakage and low tire pressure to ensure safe driving.

With Foxwell TPMS Service Tools, you can reset, reprogram, or activate TPMS sensors after replacement or adjustment. This ensures that the vehicle's ECU accurately reads the current tire pressure, enhancing overall safety and performance.

What is TPMS Diagnostic Tool?

A TPMS sensor is the central nucleus for each of your four tires which learns each individual code. TPMS sensors are programmed to work with specific vehicle make, model and year.

If customers have to replace their TPMS sensors because of repairs or tire rotations, the TPMS sensor is programmed to the vehicle and relearned with a TPMS tool to indicate which sensors are in which tires. Oftentimes, with indirect systems, that means a connection to the OBDII port to complete the relearn.

Why You Need a Foxwell TPMS Service Tool:

1. Ensure Driving Safety:

Underinflated tires reduce maneuverability, especially during tight turns and sudden stops, even before the TPMS light illuminates. TPMS reset tools enable early detection and resolution of issues, preventing potentially serious safety hazards.

2. Improve Fuel Efficiency:

Low tire pressure increases fuel consumption as the vehicle requires more energy to propel forward. TPMS reset tools help maintain optimal tire pressure levels, maximizing fuel efficiency and reducing unnecessary fuel expenses.

3. Save Money and Time:

Without TPMS reset tools, tire and sensor maintenance typically requires professional assistance, costing both time and money. With a TPMS reset tool, you can easily reset sensors yourself, saving valuable time and avoiding service fees.

Capabilities of Foxwell TPMS Service Tools:

1. Reading TPMS Data:

These tools can retrieve TPMS sensor data, including pressure levels, tire temperature, battery status, sensor IDs, and more.

2. Diagnosing TPMS System:

In case of TPMS error light activation due to factors like low tire pressure, tire changes, rotations, or seasonal tire swaps, the TPMS reset tool can be used to deactivate the warning light.

3. TPMS Sensor Relearning:

After sensor replacement or adjustment, the Foxwell TPMS service tool assists in informing the engine control module about the new sensor's location, facilitating proper sensor recognition. It supports relearning for 98% of sensors.

4. TPMS Sensor Programming:

While relearning instructs the ECM on locating the sensor, sensor programming is necessary to configure the sensor with appropriate protocols and applications, ensuring full compatibility with the vehicle's ECM.

5. TPMS Sensor Activation:

These service tools can activate TPMS sensors to initiate data collection and transmission. Foxwell TPMS service tools are compatible with activating 99% of sensors available on the market.
