designating the starting decision point as the next decision point;
transmitting the fault symptom query corresponding to the next decision point and an option to view all of the resolution points to the user access device;
receiving a reply to the query;
determining if the reply includes one of the potential responses or if the reply includes a request to view all of the decision points;
in response to determining that the reply includes one of the potential responses;
continuing said transmitting, receiving, and determining until said one of the potential responses indicates one of the resolution points or until it is determined that the reply includes a request to view all of the decision points, wherein if said one of the potential responses indicates one of the decision points then said one of the decision points is designated as the next decision point; and
transmitting the fault diagnosis corresponding to said one of the resolution points to the user access device; and
in response to determining that the reply includes a request to view all of the resolution points;
transmitting diagnostic images associated with each of the resolution points in the decision tree to the user access device, thereby allowing a user to diagnose a fault without having to respond to queries for traversing the decision tree.

Abstract
A method and system for diagnosing a fault that includes a decision tree having a plurality of decision points wherein at least some of the plurality of decision points terminate in a resolution point representing a diagnosis for the fault. Also included is a plurality of queries each having at least a first response and a second response where each of the plurality of queries being associated with one of the plurality of decision points. The system also includes a knowledge base that includes a plurality of first images where each of the plurality of first images illustrate one of the first responses. A user interface is included for presenting the plurality of queries and the illustrative first images to a user. The user navigates the decision tree by responding to at least some of the plurality of queries by viewing the illustrative first images and basing a selection between the first response and the second response associated with said at least some of said queries on said illustrative first images. Finally, the fault is diagnosed when the user navigates the decision tree until the resolution point is reached.
