DIAGNOSTIC SYSTEM FOR A MATERIAL HANDLING VEHICLE

摘要

The present invention features a diagnostic system and fail safe method for performing diagnostics tests on a plurality of components and subsystems of a material handling vehicle. The diagnostics are executed upon the vehicle in a quiescent, or non-operative state. The operational capacity of the critical components is tested prior to the vehicle going on line. Each particular subsystem of the vehicle is selected and tested in an ordered, diagnostic sequence. Each subsystem has a mechanism for activating it. The operational state of a particular subsystem is determined by sensing that subsystem in a predetermined sequence of testing events. Docket No. RC-505 36
