ANALYSIS OF DETECTING THE DIAGNOSTIC TROUBLE CODES IN AUTOMOBILES BY USING DIAGNOSIS SCAN TOOLS

Abstract

In today’s fast growing world, the automobile sector is growing rapidly over the decades. Now a day’s all the cars are computerized electronic cars. The vehicle should suddenly breakdown the roadside; the electronic components are shown the fault DTC’s (Diagnostic Trouble Codes) in the car dashboard. These DTC’s will help the technician to understand the fault and easily diagnose with the help of vehicle diagnosis programming scan tools. When a faults occurs in a vehicle for every time to take the vehicles to go nearest workshops, it is very difficult and most expensive process. Generally the mechanics can charge more money (lack of awareness) to each DTC codes separately for the troubleshooting of the faults. In some cases one DTC troubleshoot can diagnose the group DTC’s. So, we can buy a normal scanner for detecting the simple DTC’s in a vehicle and to eliminate the un-necessary replacement of the spare parts. In this paper provides some group DTC’s analysis working examples and also gives a better knowledge about the scanning and diagnosis. So, finally this project will help to reduce the cost and time factor of the faults in a vehicle with the help of OBD-II (ON-BOARD DIAGNOSIS-II).
