Yes. Just make sure that it is of the same family as your current one. You should have a DPC-203 PCM with whatever code (probably a SOD series code for 1995), so look for a DPC-203 with an ALF series code. There are vendors such as DP Tuner that can flash your current PCM to the later code as well. Many trucks have already been reflashed when they were in for service at dealerships. Are you positive yours has not had that done already? Cheers!
I doubt the OP is really referring to straight-out OBD-II, but if Seanosu is, then yes it would be a bit more involved if not impossible. More than likely he is wanting the OBD-II port active. Our trucks are not OBD-II, but kind of a hybrid ... OBD-1.5???:laugh2:
Thanks everyone for the response. I really appreciate the feedback. I Have an OBD II port in the cab of the truck close to the passenger side. Shouldn't I be able to take it to the stealer and have the PCM reflashed so at least I can read the PCM with my scanner ? I do not see a CEL light on my dash. Did the 95's not have a CEL light ?
Thanks, I'll give them a call. The sticker on the injection pump says 95 for the year and there is no emission sticker that I can find under the hood, only the tire change, belt routing and refrigerant info.
The 10th digit of the VIN determines the model year, and trumps any sticker anywhere on the truck. In any event, all the mfrs turn over the model year mid-fall, so 11/94 would definitely be a 1995 truck.
The CEL is on the far right (location is in the owner's manual); it flashes VERY briefly when you first turn the key to RUN. Briefly as in, like, 1/10 second. So watch that right side next time, but don't blink or you'll miss it, literally.
If your truck has ever been to the dealer, then it most likely has already been flashed to use the OBD-II port in the cab. But as said, generic code readers/scanners won't communicate with it. Both our '95s work with AE and Aeroforce, with no flashing required.
