I was looking through my paper work the other day on my 08 SRT. I found a Quality Upgrade Ticket it read:

IPFW 6/12 19:39 ISD LEFT FRT DOOR T47 OPEN 9001684849
37FD 6/12 14:26 FLORIDA IF DEFECTIVE HOLD FOR DISCLOSURE VE OPEN STATE09984
37FD 6/12 14:26 REMOVE DANGER! DO NOT DRIVE STICKER FIXED STICKER999

Does anyone know what the acronym ISD stand for?
