System and method for providing an interactive vehicle diagnostic display

A method comprising:

• receiving, from a server, a download including (i) an image representative of at least one circuit connected to or part of a vehicle component in a vehicle, wherein the at least one circuit includes a first circuit configured for carrying a first signal within the vehicle, (ii) symbol data associated with at least one symbol, the at least one symbol including a first symbol that corresponds to the first circuit, and (iii) a baseline value of the first signal, wherein the baseline value is based, at least in part, on a measurement of one or more comparable signals produced within one or more other vehicles that are a same year, make, and model as the vehicle, and wherein the comparable signals and the first signal are output by a common type of vehicle component;
• displaying, on a display after receiving the download, the image and the at least one symbol;
• receiving, while the image and the at least one symbol are displayed on the display, a first input corresponding to selection of the first symbol that corresponds to the first circuit;
• transmitting, to the vehicle in response to receiving the first input, a request for data representing at least one value of the first signal within the vehicle;
• receiving, from the vehicle in response to transmitting the request, the data representing at least one value of the first signal within the vehicle;
• and
• displaying, on the display while the image and the at least one symbol are displayed on the display, the data representing at least one value of the first signal within the vehicle and the baseline value.

A non-transitory computer-readable medium having stored thereon instructions that, upon execution by a computing system, cause the computing system to perform operations comprising:

• receiving, from a server, a download including (i) an image representative of at least one circuit connected to or part of a vehicle component in a vehicle, wherein the at least one circuit includes a first circuit configured for carrying a first signal within the vehicle, (ii) symbol data associated with at least one symbol, the at least one symbol including a first symbol that corresponds to the first circuit, and (iii) a baseline value of the first signal, wherein the baseline value is based, at least in part, on a measurement of one or more comparable signals produced within one or more other vehicles that are a same year, make, and model as the vehicle, and wherein the comparable signals and the first signal are output by a common type of vehicle component;
• displaying, on a display of the computing system after receiving the download, the image and the at least one symbol;
• receiving, while the image and the at least one symbol are displayed on the display, a first input corresponding to selection of the first symbol that corresponds to the first circuit;
• transmitting, to the vehicle in response to receiving the first input, a request for data representing at least one value of the first signal within the vehicle;
• receiving, from the vehicle in response to transmitting the request, the data representing at least one value of the first signal within the vehicle;
• and
• displaying, on the display while the image and the at least one symbol are displayed on the display, the data representing at least one value of the first signal within the vehicle and the baseline value.
