DESCRIPTION AND OPERATION

70-31

Fade-Out Mode
Fade-out and system switch off is triggered by the following:

l

Driver de-selection 

l

System failure.

Fade-out and system stand by mode is triggered by the following:

l

Throttle pedal pressed in neutral 

l

Brake overheat.

By gradual reduction of brake pressure, the vehicle is allowed to accelerate at a maximum rate of 0.5 m/s

2

 until 

maximum target speed is reached, or until no active pressure in system for 0.5 sec. The system then switches off, or 
into stand by mode, depending on the trigger for fade-out mode.

If the throttle pedal is pressed less than 20% (parameter), fade-out acceleration limited to 1 m/s

2

. If the throttle pedal 

is pressed 20% or more, system switches off, or into stand by mode, depending on the trigger for fade-out mode.

Off-Road ABS Control Module Programming
The programming for ABS regulation allows a higher threshold for ABS regulation when driving off-road in loose 
gravel or dirt. A locked wheel is more effective in slowing or stopping the vehicle because of the wedge that is built 
up in front of the tyre.

The programming in the ABS control module allows one or both front wheel(s) to lock up at low speeds on a rough 
road as long as the vehicle is travelling straight ahead. If the ABS ECU receives a signal from the steering angle 
sensor indicating a turn, ABS regulation will activate to prevent the lock and allow the vehicle to be steered.
