When hooking up a scan-tool to my girlfriend's daughter's 93 SC2 DOHC, I get a Quad Driver Module 1 Fault. I can clear the code, but it will return next time the engine is started. Most technical literature I have been able to get my hands on identifies a quad driver (there are apparently 2 or 4 of them) as a component internal to the PCM which is used to energize various relays and solenoids in the system The QDM is internal Pcm and contorls various components from check engine light to cooling fan to EGR soenoid and pugre solenoid. If it comes on as soon as you start the car most likely the EVAP purge solenoid is the fault. Rather than guess take it to the dealer spend 40$ and get them to do a QDM test this will tell you which component is failing and save the guess.

1994 Pontiac transport has a quad driver module failure how can this be corrected?

Look at your error codes again. It should read something like "quad driver module FAULT" not failure. It is VERY unlikely that your quad driver actually died. It is the high power control system that is in your computer. So replacing it, means replace the computer. To prevent this the Quad Driver has all sorts of internal protection hardware in its design. The likely thing that is wrong is something the Quad Driver is connected to. And that The quad driver isn't seeing every thing correctly so thus the Fault. It also can fault if there is a wiring problem from the device to the quad driver. There are Test for each component. You should to to find out which is the problem. Consult your Shop Manual.

What is the difference between stub and driver?

Stub means a Dummy model of a particular module.Suppose we have to test the interface between 2 modules A and B and we have developed only module A while Module B is yet in development stage.So in such case we can not test module A but, if we prepare a dummy module, having similar features like B then using that we can test module A.Our main aim in this is to test Module A & not Module B so that we can save time otherwise we have to wait till the module B is actually developed.Hence this dummy module B is called as Stub.Now module B cannot send/receive data from module A directly/automatically so, in such case we have to transfer data from one module to another module by some external features. This external feature used is called Driver.At a time both stub and driver are essential.Please refer to below link for understanding difference between Stub & Driver:,Fahim
