Re: OBD Code Definitions 1993 Trans Sport

In following the GM TransSport Service manual, and in tbe absence of a 'TECH 1' diagnostic tool can the Quad Driver tests be performed using a Digital Volt Meter DVM, or a multi meter, and test light. I have a feeling that most of the components can be tested without the TECH 1 toool? It looks rather abominable but doable with a little more patience.
I don't like giving up.
