Means for storing an indicator for each selected diagnostic parameter, each indicator identifying a corresponding selected diagnostic parameter Ī display for indicating the condition of at least one of the selected diagnostic parameters and Means operable, while the vehicle is in the maintenance mode, for manually selecting at least one of the diagnostic parameters Means for monitoring a plurality of vehicle diagnostic parameters In a material handling vehicle having a processor which executes a control program to operate the vehicle in either a maintenance mode or a normal operating mode, the improvement therein comprising: Each system in the vehicle can be analyzed by selecting the proper maintenance code.ġ.
The maintenance mode is divided into three diagnostic surveys: output controls, digital input measurements for analyzing switches and encoders, and analog input measurements for testing voltages and potentiometers. The vehicle is selected for maintenance diagnostics during the program mode, and then switched back to the normal operating mode, where the intermittent failures can be diagnosed. The program mode is divided into three additional modes: "maintenance mode", "configure mode" and "learn mode". The program mode can then be entered to assess just where the problem is located.

A fault code scrolls across the vehicle display screen, indicating the nature of the failure. During the normal operating mode, the vehicle operator is warned of a problem by different audible tones and patterns. The program is divided into two vehicular modes, "normal operating" and "program". The microprocessor is programmed to analyze each system during normal vehicular operation. The material handling vehicle of this invention uses an on-board microprocessor and display to allow an operator to determine whether any intermittency is present in the internal systems.
