Abstract
In some implementations, a vehicle device may receive, from a controller area network (CAN) bus of a vehicle and for a time period, messages received by the CAN bus after an engine of the vehicle is turned on. The vehicle device may combine identifiers provided in unique addresses, of the messages received by the CAN bus, to generate a unique identifier, and may utilize the unique identifier to determine data identifying a year, a make, and a model of the vehicle. The vehicle device may utilize the data identifying the year, the make, and the model of the vehicle to determine non-standard parameter identifiers associated with an engine control module of the vehicle.
