I am really having a PCM problem, HELP!
A few posts ago I stated my C/E light would come on steady after about 10min of driving. The code was QDM 640 which is Quad Driver Module which I was told was in the PCM. I purchased a reman ECC from CARDONE and put it in. 10min later C/E light again. I had code re-read today and he told me now I have 2 QDM codes coming up. Question #1: is the PCM/ECM/ECC all the same thing and go behind the glove compartment. Question #2: I had to take the old chip and put it in the newer unit. Does QDM have anything to do with the chip. Question#3: How do I have 2 QDM readings now?
