Abstract
An industrial vehicle comprising a tag reader, a reader module, and a diagnostic tag, wherein the diagnostic tag is coupled to the industrial truck within a read range of the tag reader. The reader module and the tag reader cooperate to identify the diagnostic tag and individual tags of a tag layout and the reader module discriminates between the individual tags of the tag layout and the diagnostic tag and the individual tags of the tag layout, correlates an identified individual tag of the tag layout with tag data, correlates an identified diagnostic tag with operation of the tag reader, and generates a missing tag signal if the diagnostic tag is not identified or the operation of the tag reader is not within specified operating parameters.
