PCM code reader
DO I really need to purchase a code reader for my OBD 2 Truck that is a 2002 F 250 SuperDuty?
I have a GMC typhoon and I can just put a wire between the A and B terminal to get my codes on it. I was hoping there is a similar way to get the codes on my new/used truck
Thank You

Absolutely need a code reader. Keep in mind that even though the connector is an OBDII compliant type...the 2002 (actually '99-'03) SuperDuty Trucks that are not California smog compliant...are only OBDI with regards to the PCM (ECM). It has to do with being over 8500 GVWR...and the emission laws at that time. Hope this helps...
OBTW: I purchased an Equus product and really like it.

Hmm,
I was hoping my new truck would do as my Typhoon does. I jump the ALDL port on my GMC Ty, and my service engine soon light flashes a sequence of 1, then 2 pause X 3 times = code 12 which is says..all is good. IF I throw any codes in the Ty, they will follow the 12 code. Example, it will flast a 12 3x, then if I have an EGR code, 32 3x, then on to the next code, or it will tell me no more codes are flagged by going back to a code 12.
I have seen similar code readers on the link you provided for my GMC TY, and they don't do more than putting a piece of wire in the A and B terminals of the ALDL, then watching the codes displayed on the dash via the service light. The only thing the code reader does is tell you on a display the actual code that's flagged. Now, my Ty is OBD 1, but there's gotta be a simple way to jump the port to retrieve the codes on the OBD 2.
I know the ALDL is called something different on a Ford, but same thing.
.....So, your telling me I can't just jump the port on my F250

On my jeep you had to turn the key to run three times with the odometer button held down... then it would display codes on the odometer readout.
Haven't found anything like that for my truck though.

To my knowledge there isn't anything like that on these trucks. I could be wrong, but I haven't heard or seen anything about it. Also I missed what engine you have in there as well? Not all engines follow the same communication line and require very specific code readers.
Also, I don't get what your aversion is to a code reader? I use mine all the time and not just for DTC retrieval either. There is alot of stuff that you can do with the computer controlled vehicles that make things easier and less time consuming.
