The ABS system is disabled!
The system operates perfectly just as any other braking system without ABS.
The detection of malfunctions may require more or less time according to the type of failure.
Error detection logic foresees that for the errors to be diagnosed one or more conditions must persist
within a given time.
If during this given time one of the conditions is missing but then it comes back, the timer is reset and
the system is no longer able to diagnose the error.
The ABS system continues to be inactive.
