On-board diagnostics (OBD) programming assist devices and methods of assembling and using the same

A method of operating an adapter, the method comprising:

• electrically coupling a first interface of the adapter with a communication port of a modifiable device;
• electrically coupling a second interface of the adapter with a diagnostic device;
• and
• initiating a modification mode of the modifiable device via the diagnostic device, wherein the adapter comprises:
• power converter circuitry configured for:
• receiving a first signal from a first pin of the first interface;
• and
• providing a second signal to a second pin of the first interface, wherein the second signal is configured to facilitate the modification mode for the modifiable device;
• over-voltage protection circuitry electrically coupled between the first pin of the first interface and the power converter circuitry;
• voltage regulator and over-current protection circuitry electrically coupled between the power converter circuitry and the second pin of the first interface;
• output shutoff circuitry electrically coupled between the voltage regulator and the over-current protection circuitry and the second pin of the first interface;
• and
• controller circuitry configured for:
• providing a switched signal to the power converter circuitry;
• receiving an enable command signal from the second interface;
• and
• upon receiving the enable command signal, deactivating the output shutoff circuitry.
