if you disconnect the negative battery terminal for several minutes it will reset. I believe the standard is 30 minutes, to be on the safe side.
Newer models require a 'scan tool' to reset, available at auto parts stores, but I doubt that would apply to a 2001.
Hope this helps! =)
Year One is good, but I usually post on moparts.com for parts. Just did restos on a 66 coronet and a 68 RR and I always start there. Lots of Mopar nuts with extra parts laying around... Plus info on where else to look! Good luck!
