Claim 18:
19. A non-transitory computer readable storage medium readable by a processing circuit and storing instructions that when executed by the processing circuit perform method operations, comprising:
receiving an indication one or more of a plurality of on-board autonomous sensors are non-functional and a secondary autonomous sensor system including one or more replacement sensors are installed upon an autonomous vehicle;
verifying the secondary autonomous sensor system based on a security check, wherein the security check indicates a correct number and type of replacement sensors are connected to an automated driving controller, wherein the automated driving controller is in electronic communication with a receptacle, and wherein the receptacle electronically connects the automated driving controller to a corresponding plug of the secondary autonomous sensor system;
in response to determining the secondary autonomous sensor system has passed the security check, performing a data synchronization that determines missing sensor data required by the automated driving controller;
performing a redundancy check between the one or more replacement sensors and the plurality of on-board autonomous sensors;
determining data received from the one or more replacement sensors are valid based on the redundancy check; and
in response to determining the one or more replacement sensors are valid based on the redundancy check, operating the autonomous vehicle in a limp home mode, wherein the limp home mode limits one or more autonomous driving features.
