FAULT DIAGNOSIS METHOD FOR VEHICLE
First Claim
1. A fault diagnosis method for a vehicle, comprising the steps of:
- detecting, by a controller, whether a reference engineering code (REC) has been generated;
measuring, by the controller, a time for which the reference engineering code (REC) has been generated, if the reference engineering code (REC) has been generated as a result of performing the detecting step;
calculating, by the controller, a percentage of the reference engineering code (REC), based on both the time for which the reference engineering code (REC) has been generated and a preset time, after the measuring step;
storing, by the controller, the reference engineering code (REC) and the percentage of the reference engineering code (REC), after the calculating step; and
when a request signal is received from a diagnostic device, providing, by the controller, an output signal that includes the stored reference engineering code (REC) and the stored percentage of the reference engineering code (REC) to the diagnostic device, after the storing step.

Abstract
A fault diagnosis method for a vehicle includes steps of: detecting, by a controller, whether a reference engineering code (REC) has been generated; if the reference engineering code (REC) has been generated as a result of performing the detecting step, measuring, by the controller, a time for which the reference engineering code (REC) has been generated; after the measuring step, calculating, by the controller, a percentage of the reference engineering code (REC), based on both the time for which the reference engineering code (REC) has been generated and a preset time; after the calculating step, storing, by the controller, the reference engineering code (REC) and the percentage of the REC; and after the storing step, when a request signal is received from a diagnostic device, providing, by the controller, an output signal that includes the reference engineering code (REC) and the percentage of the REC to the diagnostic device.
