ECAS
Vehicle type
Vehicles with air suspension that require ECAS functions which TEBS E does not
provide.
Only in combination with TEBS E Modulator (Premium)
Purpose
• Implementation of 3-point control
• Tire impression compensation
• Lateral control for tippers
Function
The operating data between TEBS E and ECAS is exchanged via the K-line. The
internal level control functions of the TEBS E are deactivated; the ECAS-ECU is
prioritised.
With TEBS E4 or higher, the External ECAS is only supported by the
TEBS E Multi-Voltage.
If a repair is required, a Reman modulator should be used.
The TEBS E should take over control of the lifting axles. Only then is the position of
the lifting axle(s) transmitted correctly to the towing vehicle.
Please refer to the documents ‘External ECAS for trailers – system descrip-
tion,’ see chapter 4 ‘Introduction’, page
=> section ‘Further information’.
