Forced lowering with Trailer Remote Control
Information on operating the Trailer Remote Control, see chapter 10.2 ‘Operation
with Trailer Remote Control’, page
The lifting axle function can be permanently deactivated in addition to
forced lowering. Up to two separately controlled lifting axles can be
permanently lowered individually by means of two separate switches
or via the SmartBoard.
Two separately controlled lifting axles can be lowered individually by
means of two separate switches or via the SmartBoard.
If the load status only permits lifting one axle, this function can be used
to lower a specific lifting axle so that the other lifting axle is automati-
cally lifted as a result.
Forced lowering of the rear lifting axle will also deactivate OptiLoad
and OptiTurn.
Traction help is deactivated simultaneously with deactivation of the
front lifting axle.
Lifting axles are only lifted under automatic lifting axle control if the vehicle is within
the parameterised threshold values for speed and bellows pressure.
The input levels (positive or ground) coming from the towing vehicle can be se-
lected in the TEBS E Diagnostic Software.
There are two ways to define parameters for the forced lowering function in the
TEBS E Diagnostic Software:
• Forced lowering affects all lifting axles or only the 2nd lifting axle.
• Forced lowering is possible via switch, button, Trailer Remote Control or
SmartBoard.
