Introducing i-sensor® HD – the Universal Commercial Vehicle TPMS Solution

Why are we talking about Commercial Vehicle TPMS?

Being well established as the leading TPMS provider to the UK aftermarket, we are always looking at the TPMS market and identifying any changes in legislation, new technologies and general trends.

Since TPMS became mandatory fitment for all new cars in November 2014, there has been call for TPMS legislation to become effective in the commercial vehicle sector, with many believing that this would have an even greater impact on road safety and the environment.

It has now been announced that TPMS legislation will become effective for CV applications in 2022.

What is i-sensor® HD?

i-sensor® HD is the first, universal TPMS system developed for the commercial vehicle aftermarket with the aim to save time and simplify the inspection and replacement of OE TPMS.

The benefits of i-sensor® HD are:


  • Convenience: If a sensor is broken, then a replacement can be made in as little as 18 seconds, without the need to go through a dealer.
  • Flexibility: Blank sensors are programmed to be fitted to the majority of manufacturers wheels from Mercedes Actros right through to DAF CF and XF
  • Non-invasive, real-time tyre pressure checks: Autogem’s handheld device checks commercial tyre pressures at the same time (without the need to unscrew valve caps and put an airline on) thus saving fitters even more time
  • Battery life status: User-friendly process also includes instant information on TPMS battery life to 1%, allowing maintenance to be scheduled accordingly
  • Easy to fit: Replaced TPMS sensors are mounted to the centre of the wheel rim, rather than the valve or outside the wheel, resulting in fewer breakages.
  • Coding and pairing: New sensors are created in seconds through Autogem hardware and can copy the unique original ID code into a new replacement sensor circumventing the need for time consuming relearn processes.
  • Cost Saving: Being universal, the sensors themselves can be somewhat cheaper than the OE parts and there is no requirement for expensive specialist TPMS valves, any relevant truck valve can be used as the sensors are mounted around the inside of the rim instead of at the base of the valve.
  • Identification: A valve cap with a TPMS logo is included for easy external identification.

What does the CV market do about tyre pressures currently?

Clearly tyre pressures are important to fleet management companies. As there currently isn’t any obligation for CV manufacturers to provide tyre pressure monitoring as standard there have been a number of suppliers in the market offering retrofit TPMS systems where there is no OE option. There are even solutions available that take into consideration both the truck and trailer wheels. These systems are often then linked into some type of retrofit display in the cab and can even be linked into remote fleet management systems. This gives tyre pressure data visibility to either the driver, the fleet manager or in some cases, both.


More OE TPMS systems are now being introduced, with the likes of DAF & Mercedes Benz installing such systems on their new trucks and Setra & Mercedes-Benz also fitting them to their new buses. These systems are able to report the tyre pressure data directly to the driver dashboard / safety console.

How do these OE systems work & what problems do they face?

These OE systems utilise battery powered sensors located inside each wheel to transmit data to receivers that can translate and display warnings to the driver. Often, these sensors are located at the base of the air valve in the wheel and it is not easy for a tyre technician to identify whether a truck wheel has sensors installed, making them particularly susceptible to damage during tyre repair or replacement and also in the event of catastrophic tyre failure.

Another issue that is already becoming significant is battery life. These sensors are designed to transmit whilst the vehicle is being driven. The high mileage, regular use of commercial vehicles is resulting in the batteries being depleted much faster than the 5-7 year life expectancy of pressure sensors in the passenger car market. We have even heard of sensors being up to 30% depleted even before they have been fitted to the vehicle.
