If I am correct here....
PCM (powertrain control module) controls engine and trans
BCM (body control module) controls all accessories (airbags, windows, locks, radio, etc)
SDM (sensing/diagnostic module i think) controls airbag deployment
DTc = diagnostic trouble code I think (it's what you get with a scan tool, the trouble code)
I am not a real tech so someone good can fill in the rest.
