For over twenty-five years ADMS has been delivering the most efficient engine repair information and training to tens of thousands of repair shops across North America. Now we are offer unlimited access to the complete library of training and technology on DeadOnDiagnostics.com.

Our tutorials offer straight-line testing procedures, field-tested fixes and independently researched measurement values that are simply not available from any factory resources or computer databases. We show how to fit new technologies into normal diagnostic routines, when to use a particular technique, why you apply it, and how to get the job done in the quickest way possible.

We deliver the diagnostic shortcuts that experts use instead of confusing flowcharts found in most shop manuals and softwares. Our commitment to the automotive aftermarket is to continue to provide the most efficient and effective solutions for real world problems, each and every day.
