A QDM (Quad Driver Module) is a component inside the ECM (Electronic Control Module). The ECM is what controls the engine functions. I don't know how you came to the conclusion that you need a new QDM, but if one is bad, you have to replace the ECM. Also, if you really do have a bad QDM, then more than likely a component that the QDM controls, failed, killing the QDM. Could be a shorted TCC Solenoid, shorted EGR solenoid, etc...
