A method includes receiving technician data indicative of at least one diagnostic characteristic associated with one or more vehicles, wherein the at least one diagnostic characteristic is representative of a technician servicing event; interpreting the technician data to facilitate remote monitoring of the one or more vehicles; determining a potential root cause for a fault code of a particular vehicle of the one or more vehicles by comparing data of the particular vehicle to the technician data of one or more other vehicles; receiving a display request for a graphical user interface for formatting the graphical user interface in a desired graphical format based on the technician data; and providing the graphical user interface in the desired graphical format to a display device.

Diagnostic data visualization methods

An apparatus includes an aggregation circuit, an analysis circuit, and a data visualization circuit. The aggregation circuit is structured to receive at least one of (i) vehicle data indicative of a least one operating characteristic of one or more vehicles from the one or more vehicles and (ii) technician data indicative of at least one diagnostic characteristic of the one or more vehicles representative of a technician servicing event. The analysis circuit is structured to interpret the at least one of the vehicle data and the technician data to facilitate remote monitoring of the one or more vehicles. The data visualization circuit is structured to receive a display request for providing a graphical user interface to a user display device. The display request includes configurable options for providing the graphical user interface in a desired graphical format including the at least one of the vehicle data and the technician data.

A system and method for engine parameter trending in which the engine control module (ECM) periodically stores to non-volatile memory various engine operating parameters over the life of the engine. The system is configurable such that a variable number of samples of a variable number of engine parameters can be stored. In addition to storing each engine parameter, each write to non-volatile memory is also time stamped. This data is used to track the health of the engine over its life cycle. Such data can be useful in providing decreased down time due to increased troubleshooting ability. The system includes a variable number of calibratable predetermined trigger points available so that the data is always logged under the same operating conditions. All triggers must be satisfied for a specified time in order to ensure consistent engine operating conditions when each data set is taken. When all of the predetermined input trigger thresholds have been met for a calibratable predetermined length of time and a predetermined time interval has been reached, the designated parameters are stored in non-volatile memory for extraction and use by a service tool. If the trigger preconditions are not satisfied, the ECM will wait a percentage of the data-logging time increment in order for the preconditions to all be satisfied before writing the monitored parameters to non-volatile memory. If the preconditions are not met after that additional time period, the ECM will evaluate the individual conditions and write to non-volatile memory whichever monitored parameters are valid, given which preconditions have been met.
