Method of using a test pattern for testing functionalities of external devices when an item is attached to a vehicle

A system comprising:

• a communication module;
• and
• a processor storing instructions in a non-transitory memory that, when executed, cause the processor to:
• identify an item mechanically coupled to a vehicle;
• establish a first connection, via the communication module, with the item;
• generate a test pattern for testing a device from a plurality of devices, wherein the device is at least one of part of the vehicle, and part of the item;
• determine control of the device;
• and
• actuate the device to verify a functionality of the device based on the test pattern.
