Code 26 QDM fault means there is a shorted condition in the circuit connected to the QDM. You will have to trace the short to get it fixed.
it is located inside the PCM ( the cars computer). An errorcode of a QDM means the unit - like a sensor or relais - connected to this QDM reports a error.
basically, p 1080 is a fault code that faults many codes, it faults codes that is a code for a fault, when you get a faulty code you need to un fault it with a code called p 1080, which is a fault code that measures fault codes!

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.
