95 ZR-1:

Would someone please explain the Quad-driver fault? It lists as on/off. Service manual does not go into detail other than to say quad-driver is on the ECM (for my 95 manual at least) and controls injectors.

What do they do?
What is fault "on"?
Is it bad that they show fault "on" after running?
How do you address it if it is a problem?
What sets fault "on"/"off"?

More to come,
Ted
