Abstract
A real-time maintenance alert system for use in a heavy duty truck having an engine including an engine controller having a communications data link is provided. The system includes an engine item sensor and a non-engine item sensor. Control logic at the engine controller produces an output signal at the data link in response to the presence of an engine item real-time fault condition. A display device transmits and receives information over the data link, and processes the control logic output signal. The display device generates an output signal indicative of the engine item status. Further, the display device directly receives and processes the non-engine item sensor output signal, and generates an output signal indicative of the non-engine item status.
