Abstract

A self-contained, on-board diagnostic system integrated with a control system and method of using the same. Various control system coefficients and parameter settings may be set and edited with the on-board system, without the use of external hardware. In certain embodiments, an operator panel display may be used as a display for the on-board system. A menu navigation scheme can be employed to access a plurality of screens in an organized, efficient manner. The on-board system can be adapted for use with a tracked trencher and/or other mobile equipment.
