As automobiles become more and more computerized, the need for automated troubleshooting equipment becomes more important. Since mechanics need to be knowledgeable in electronics, the cost of auto repairs are also increasing. Therefore, the market for automobile diagnostic tools is expanding. 

The project involves the investigation of a diagnostic tool called the ALLSCAN and the development of an ALLSCAN companion to speed up troubleshooting time. For this project, the ALLSCAN is being used as a diagnostic data interface between the electronic control module of the automobile and the portable computer system which has been designed. The portable computer system allows more diagnostic data to be examined simultaneously and continuously on displays. The portable computer system utilizes an 8751H microprocessor to acquire diagnostic data from the ALLSCAN, organize this data, and then store the data in 64K bytes of RAM memory. The diagnostic data can then be downloaded via an RS-232 connection into a personal computer for inspection.
