DTC	Description	System Response
268-02	Programmed Parameter Fault: Data erratic, intermittent, or incorrect	The Graphical Display has determined that a configuration parameter is not programmed. The Graphical Display will display the parameter causing the problem on the Cat^® Electronic Technician (Cat ET) Service Tool.

The programming parameters identify conditions related to the programming of the Graphical Display or a signal failure. A failure of the internal program of the Display is associated with this diagnostic code as well. The fault messages displayed in Cat^® Electronic Technician (Cat ET) Service Tool or via the operator monitor include "programmed parameter fault" or other machine monitoring failures.

Possible causes for an FMI 02 diagnostic code are:

The sales model and product identification are not programmed into the Display.
The Graphical Display is incorrect.

Note: The correct sales model and product identification must be programmed when new software is flashed to the Display.
