. . cleared all but the DTC 19 on DM module (as expected) and the DTC 3 on EA/CC/ISC module.
I know what's causing the DTC 19 and it's probably been there for an half decade. The only remaining code that's a problem is DTC 3 on socket 7, which (I think) is the cruise control. I'm wondering if I spiked something when I took off the ETA with the engine running.
I read that there is a fuse in the diagnostic module. Could that be the problem (or maybe another fuse in one of those modules)?

OK, good deal . . now there's a base from which you can proceed.
DM: #4: Either the AIR pump is bad or the vacuum line is broken to the AIR pump. Do you hear the AIR pump start on a cold engine??
#6: the "CC" is in the EA module but personally, I've never seen a bad EA module. That code, most likely, is caused by other problems. . .
#19: Maybe you have a bad injector or vacuum leak that will cause DTC#19. Check those areas and see what you find. If all is ok, I have a eprom that will fix that.
EA: #6: I would change the S16/3 asap! You read what caused my "ETA" problems and it was the switch. The contacts were corroded. MENU#24 at the bottom of the page.
There's fuses in the Base Module (Menu#8); none in the DM module.
