The present disclosure provides systems and methods for remote vehicle diagnostics. The remote vehicle diagnostics are obtained based on a vehicle identification number for a vehicle connected to an electrical connector of a vehicle diagnostic system host device. A vehicle electronic configuration file is provided to the host device to control access to one or more vehicle control modules.

Apparatuses, systems, and methods for remotely capturing automotive vehicle diagnostic information, monitoring, and controlling

A tester and method for testing for a leak in an evaporative-emissions system of a motor vehicle comprise a/an power supply, computer, display communicating with the computer, analog-to-digital board communicating with the power supply and computer, pressure sensor communicating with the board, housing into which the power supply, board, and sensor are integrated, stationary enclosure, and test connection including a hose to the enclosure. A fuel-vapor pressure-rise rate is recorded with an engine of a motor vehicle turned 'off.' A value is recorded that directly correlates with an out-gassing effect created by a volume, blend, and temperature of fuel. A 'purge' cycle occurs at idling of the vehicle within a short period of time. The engine applies a vacuum to a fuel-delivery system of the vehicle. Vacuum decay is recorded. A leak rate is determined by off-setting the recorded fuel-vapor pressure-rise rate with the recorded vacuum decay.

Evaporative emissions leak tester and leak test method

A test apparatus for an evaporative emission system includes a source of pressure (positive or negative), a sensor for sensing the pressure generated in the evaporative emission system, and an ECU which controls the operation of the source of pressure and receives signals from the sensor reporting the pressure in the vehicle evaporative emission system over time. The ECU compares the sensed data with the stored data representing standard baseline sample vehicles without any leaks to determine the presence of a leak in the evaporative emission system.

Reporting tools possess improved filtering, display and alerting methodologies offering enhanced versatility. According to one aspect of the invention, the method has an independent data filtering mechanism, an independent output function that populates an n-dimensional array, and an independent display function. According to a different embodiment, a set of parameterized query relationships organizes a series of data filters into a graphical representation of a parent/child hierarchy in order to execute a series of hierarchical queries where each simple query builds a final query that is complex. According to yet a further alternative embodiment, Boolean logic is used in a series of n-number hierarchical filters, and a combination of n-number outputs, to generate notification in the form of emails/messages/etc. based on data that is dynamically entered into the system.
