ALP5Unexpected ABS operation at low speed and slight pedal
pressure
NOTESOnly address this customer complaint after a complete check with the diagnostic
tool. Warning: ABS control is sensitive to poor traction (icy roads, wet cobblestones,
etc.).
It is possible to feel brake pedal vibrations which are associated with the reaction of the system in particular
circumstances, such as:
– crossing rumble strips,
– tight cornering with lifting of the inside rear wheel.
These vibrations may be linked to simple brake limiter activation, when the pressure on the rear axle is limited.
If the fault is different, check the speed sensor connectors (micro-breaks).

ALP6 Unexpected ABS system intervention on a poor road surface
NOTESOnly address this customer complaint after a complete check with the diagnostic

On poor road surfaces it is normal to feel hesitation and vibrations of the pedal as well grating which is more
significant than on good surfaces.
This gives the impression of a variation in efficiency, but this should be considered normal.
