: How do I know if I wiped my computer?

I cleared all the codes on my 98 Cadillac deville yesterday while my car was running and when I hit clear pcm codes my car died and will not crank back... I tried disconnecting the battery cable to see if it might reset it.... My friend seems to believe I erased the computer and it needs to be reprogram... Does anyone know anything about this...

Try disconnecting the battery cables and touching the ends together... that might reset/clear some modules

............and you probably did not "erase the computer" (Powertrain Control Module). Damn near impossible using OnBoardDiagnostics. This problem sounds like something to do with TheftLock ???

yeah it does sound like some sort of TheftLock issue... and I agree that the modules are probably fine
