TPMS 2.0 Installation guide
4Innovative Vehicle Solutions 2023
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.
Haldex TPMS 2.0 at a glance
The Haldex TPMS 2.0 monitors both the pressure and the temperature of each individual trailer tire and is
compatible with the Haldex EB+ 4.0 EBS for trailers.
TPMS 2.0 features include:
› Constant measuring of tire pressure and temperature
› Low pressure warning
› Auto-detection
› High Temperature warning
› Over pressure warning
› TPMS Malfunction warning (self-diagnosis)
› WUS low-battery notification
› Compliance with UNECE Regulation 141
Fully compliant
Our improved TPMS 2.0 keeps up the high standards of Haldex, all while being up to industry standards.
The TPMS 2.0 is compatible with the UNECE R141 legislation. Haldex next generation TPMS 2.0 in combination
with EB+ 4.0 is fully compliant with the revised legislation for both OE and aftermarket.

TPMS 2.0 components
Receiver control unit (RCU)
The RCU receives sensor information, determines the system status, and
sends it to the EBS via the trailer CAN.
Wheel unit sensor (WUS)
The TPMS 2.0 wheel unit sensor (WUS) is a pressure sensor which is
clamped inside the tire using a velcro belt. It measures the pressure and
temperature inside the tire and transmits all the measurements by radio
frequency (RF) to the RCU.
Belt assembly
A velcro belt is used to attach the WUS (042727219) to the tire rim. One
belt part number covers all rim sizes from 17.5'' to 24.5''
WUS Sole (optional)
The sole should be used / clipped onto the WUS for smaller diameter rims,
which have a small drop centre width from 25 mm to 40 mm.

TPMS 2.0 Smart DIAG Tool
The TPMS Smart diagnostic tool is a tool used to send
a low frequency (LF) trigger to the WUS. This tool is
operated by an Android mobile phone application.
It is used to configure the system for the first time,
writing the trailer configuration (number of wheels
and axles), recommended pressure per axle, warning
thresholds and WUS positions into the RCU.
TPMS 2.0 Smart Box
The TPMS 2.0 Smart Box is connected to the mobile
phone and used to read the TPMS wheel sensor ID's.

TPMS 2.0 label
Indicate the presence of a WUS in the wheel by
sticking the TPMS label onto the wheel rim next to the
valve. The WUS must be located by eye before the tire
is removed from the rim.
Valve indication
Indicate the presence of a WUS in the wheel by fixing
a plastic colored tube (blue or other) onto the wheel
valve nose.
P/N 006700021_M
The TPMS 2.0 wheel unit sensor (WUS) can be mounted on all tire rims compliant to national and international
tire standards from 17.5 up to 24 inches diameter.
Tire standards:
› European tire and rim technical organisation (ETRTO)
› Tire and rim association (TRA)
› Japan automobile tire manufacturers association (JATMA)
For all rims which do not respect these specifications, customer must send all rims drawings for Haldex Brake
Products for approval.

Examples of major mounting
problems
Example 1
There is a limitation of the mounting of the WUS on
small width drop centre tire rims.
Do not mount the WUS, if the flat width available in
the drop centre is below 25 mm.
Mount the WUS with the sole, if the flat width
available in the drop centre is between 25 mm to 40
mm.
Mount the WUS without the sole, if the flat width
available in the drop centre is larger than 40 mm.
Larger than 40 mm = OK to mount the WUS without the sole
OK

Larger than 25 mm = OK to mount the WUS with the sole
OK

OK

Flat width 25 - 40 mm = Not OK to mount the WUS without the sole

Example 2
Mounting with a wrong position on a conical rim profile.
Note: The angle between the sensor and the wheel axis must stay below 15° in order to avoid bad acquisition of
the acceleration level by the sensor. Also the more the sensor is raised from the rim, the greater the tire can catch
it during mounting / dismounting phase.
On a conical rim
profile, always locate
the TPMS 2.0 WUS on
the lower perimeter to
avoid sliding
Sliding under vibration
Attaching the sole adaptor (optional)
For small diameter rim with small drop centre width (25 mm minimum): => clip the sole onto the housing of the
WUS before introducing the belt in windows.
