A San Francisco engineer wired Claude to the electronic control unit of his 1994 Jeep Cherokee. The car was released before the appearance of the standard OBD-II connector, so the usual bluetooth scanners do not work with it.
Instead of the old Chrysler brand scanner, an Arduino Nano microcontroller costing about $3 was used, and neural networks provided access to the microcontroller. Now the driver can ask the AI in plain language to check coolant temperature, battery voltage or reading history, as well as find errors in engine operation.
