Knowledge of TPMS
All new passenger cars after 2014 must be equipped with an automatic tire pressure monitoring system, TPMS. On many cars, this system consists of an electronic valve which measures the tire pressure in the wheel. Some cars do not have these valves, but instead use the ABS system (indirect) to ensure that there is enough air in the tires. It is therefore important to know if you should use TPMS valves in your new set of wheels. Tips If you can see the tire pressure  inPSI/BAR on your dashboard, you have TPMS valves in your wheels. You can also find your car in Car overview

A TPMS valve consists ofa valve, a CPU and a battery. Each car model has its own software to communicate between the car's computer (CPU) and the TPMS valve. This is called a "protocol". All TPMS valves have a unique ID number. For a TPMS valve to work on the car, the valve must have the correct protocol and ID number.

There are two systems for cars where you need TPMS valves:

Plug & Play:The car itself loads the ID number of the new TPMS valve. You can freely install the new valves in the wheels, after which you must reset the TPMS on the car's dashboard. After a short drive (max. 25 km), the car's CPU will find the new valves itself (and load the new ID number).

ODB II:The new TPMS valve ID number must be loaded into the car's CPU via the ODB II input. The car's CPU cannot find the new TPMS valve ID number by itself, so you have to load the new ID numbers into the car's CPU via the ODB II input.
