Haldex TPMS 2.0 is a tire pressure and temperature monitoring system for any commercial vehicle trailer equipped
with EB+ 4.0. The EB+ 4.0 shall facilitate the transmission of pressure and temperature for each wheel via
ISO11992 CAN to the towing vehicle and the EB+ Info Centre can be used locally to display the pressure and
temperature on the trailer.
The wheel unit sensor (WUS) measures the pressure and temperature inside the tire and transmits all the
measurements by radio frequency (RF) to the receiver control unit (RCU). The RCU then determines the system
status and sends it to the electronic braking system (EBS) on the trailer CAN bus. The EBS then transmits this
information to the dashboard which can display the required information of pressure, warning, alerts and system
status for the vehicle driver.
The system is configured and diagnosed through CAN communication using Haldex DIAG++ software, and by
using the Haldex TPMS phone application. A trigger is used for low frequency (LF) communication to the wheel
unit sensor (WUS) and is used to force the WUS to send it's unique identification code (ID) to the RCU.
