Abstract: Disclosed herein are methods, systems, and devices for assisting programming of vehicles via on-board diagnostics (OBD) ports. In one embodiment, a programming assist device includes a first interface configured to be electrically coupled with an OBD port of a vehicle, power converter circuitry, and a second interface configured to be communicatively coupled with a vehicle diagnostic device. The power converter circuitry is configured for receiving a first voltage signal from a first pin of the first interface and providing a second voltage signal to a second pin of the first interface. The second voltage signal is configured to facilitate a programming mode for the vehicle.
