The TEBS E modulator (multi-voltage) cannot be combined with Trailer Central
Electronic.
Purpose
Electrical supply, sensor data transfer (bellows pressure sensor, wear sensor) and
monitoring of the TEBS E via the CAN line.
Only the speed sensors and a possibly installed nominal value pressure sensor
have to be connected to the TEBS.
The Trailer Central Electronic can also be used for additional functions such as lift-
ing axle control or brake lining wear indication.

Solenoid valves and sensors are also required.
Start-up
For start-up, TEBS E is put into operation first and then Trailer Central Electronic.
Trailer Central Electronic is no longer supported.
If a repair is required, a Reman modulator should be used. As an al-
ternative, the supply can be implemented using the Premium version
of TEBS E4 or higher. The cable 449 348 … 0 is split in a distributor
box for this purpose: A cable 449 349 … 0 is used to connect the sup-
ply voltage to In/Out and CAN is connected using a cable 449 537 … 0
to GIO5.
