Requirement TPMS Sensors
The requirement applies to new models that have been granted type approval since November 1, 2012. Since November 2014, all new cars must have TPMS (Tyre Pressure Monitoring System). Since January 2015, a vehicle will be rejected if the TPMS system does not work, if applicable.
This is based on European Standard 2010/48EC.
The system must warn the driver when pressure in one or more tyres falls below 20% of the required value.
Types of TPMS systems
There are currently two different types of TPMS systems on the market, indirect and direct. The major difference is that indirect systems do not use pressure sensors. These indirect systems make a calculation based on the circumferential speed, diameter and/or height ratio of a tyre (ABS system). A direct TPMS system uses a pressure sensor in the tyre. In newer cars, this information is shown on the onboard computer display.
The Autel MaxiTPMS system works with pressure sensors mounted in the tyre, the advantage of which is that they can be programmed and thus readable on any car that has TPMS on the onboard computer.
These Universal Multi Sensors (MX-Sensors) have a high coverage ratio. This means that a universal valve can also be applied in addition to the OE sensor valves. As a motorist, you also save costs thanks to very favourable prices.
An additional advantage comes during the tyre change. Both summer and winter sets can be read by the Autel Maxi TPMS. This way the TPMS Sensors do not have to be swapped. This in turn reduces the risk of damaging your TPMS system or rims. Tyre change will also take less time to perform.
