Pressure sensor 441 044 101 0 / 102 0
The pressure sensor generates the nominal brake pressure value as a CAN signal
on towing vehicles with no CAN line or on overlength trailers in order to meet the
necessary timing requirements in accordance with ECE R 13.
In connection with the Trailer EBS E1, the external pressure sensor is connected to
the yellow hose fitting and to connection Y "Pressure sensor" of the CAN router/-
repeater. With a Trailer EBS of the D generation, the pressure sensor is connected
to the "IN/OUT 2" connector of the T-EBS modulator.
!
As of version 1.5 of the Trailer EBS E (production date from CW 49/2009), in the
diagnostic software "Trailer EBS E" with connected external pressure sensor on
the CAN router/-repeater, select setting: "Nominal pressure sensor on R/R" to
improve the communication between the devices.
