[QUOTE="Justin@DP-Tuner, post: 1180397, member: 1413"] Very strange... That is a hybrid early and late 1999 California PCM. Also a really early model 2000 Excursion could have that. It should have the glow plug relay with a shunt on it (just like the Cali model 1997 trucks had). You can actually use tunes for a DPC-422 on that though with some modification to the relay. LOL I always have to think twice before responding to PCM code questions. Soooo many combinations out there... BTW, Late 2000 and 2001 model Excursions had the GPCM, and a DPC-452 PCM code. Same as 2000-2001 Cali model trucks. The EX codes were AXD and EBM, respectively. [/QUOTE]
