Use and Interrogation of the Diagnostic Connector
By John R Cookson, B.Sc, C.Eng, MBCS
This manual explains the functions and uses of that mysterious black box located near the air filter-the diagnostic connector. The procedures apply equally to most models of Mazda MX5, Miata, and Eunos Roadster 1989>2000. The purpose of this manual is to enable the home mechanic or independent garage to access the self diagnostic facilities of the MX5 which are normally only available to Mazda dealers through the use of their factory provided service tools. Includes a free DIY led probe to get you started!
Suitable for use with all Mk1 models, 1989>1998 and all Mk2 models, 1998>2000
