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 is still inactive.
Example:
- error code 5D93 requires some minutes before it is diagnosed during the given time:
•
the ABS warning light ABS keeps flashing
