Broken supply lines can be detected by the OBD (On Board Diagnostics) and reported
to the µController.
Note: The OBD is only useful when the clamping function is enabled.
In the case of interrupted supply lines, the µController may warn the user.
If two sensors are placed in parallel, the output of the remaining working sensor may be
still used for an emergency operation.
