Manages the braking system by setting deceleration to the parameters measured by the various system components.
It communicates with on-board electronic systems via a CAN line and is connected through two polarized connectors.
Though offering the possibility of a blink code displayed via the ASR warning light for preliminary diagnosis, the electronic center
is provided with an advanced self-diagnosis system capable of identifying and storing any intermittent anomaly to an operating
system subject to environmental conditions, and ensuring proper and reliable repair.

Operating logic
The objective of the electronic center is to slow down the vehicle as fast as possible, guarantee its stability and avoid the tendency
to lock wheels. When braking, the center is informed of the following to reach these objectives:
-
braking intensity required by the operator via the rear axle pressure sensor
-
slowing reaction due to pressures made available via signals from the speed sensors.
Ongoing monitoring and processing of these data referred to the objective set required activation of rear axle modulating valves
and consequent braking optimization.
