Default What pins do I need to jump on the diagnostic plug to get DTC’s..?

I do not have a diagnostic scanner that will allow me to read the diagnostic trouble codes on my 2000 Ford ranger XLT 2.5 L. I’m using a paper clip to jump the pins on the plug however, I’m not sure of which pins need to be jumped, could someone shed some light on this for me please?

On a 2000 you do not use jumper wires to pull codes. you will need a code reader.

Are you sure..? I believe i read in a chilton awhile back that a paper clip could be used to jump two of the pins in the diagnostic plug without needing a scanner.. I’ve done this exact procedure on same year vehicles and different makes just not this make & model.. I was told that all manufactures build this option into their vehicles to allow anyone regardless of having a scanner to be able to read diagnostic codes..

Not to my knowledge, that was a pre-OBDII technique.

How would you display the codes?

Traditionally you'd be looking for voltage pulses on an output pin. EEC-IV had a system of 2 and 3 digit codes (depending on year) that pulsed up to 9 times for each digit with a short pause between digits, and a longer pause between codes. I've never heard of anything analogous for OBD2. It's also not nearly as necessary when all brands use the same basic interface under the dash and scanners are dirt cheap.

After inserting the paper clip into the diagnostic plug on a set of two specific pins and turning the ignition on and off in a specified series the ODB system will then be put into a (Test Mode) which will allow the check engine light to flash on the dash in order to display the DTC. For example if your code is a 341 the light will flash three times pause one second, flash four times pause one second, then flash once, then pause for, four seconds and then move on to the next code. The four second pause separates the Codes.. atleast that works on Chrysler, Chevy and some imports.. Hope this helps..

Right, but what vehicle used that method from 1996 onward?

It had dropped a cyl and I was able to get a cyl misfire code on #2 and replaced the plugs and ultimately the injector.. all is well now..

I am by NO means a mechanic, I am however an Network Engineer and have let’s say a “Basic” understanding of how software and interfaces work.. There is usually always a “Backdoor” if you will, to allow for an alternate way to obtain data from any piece of software/interface and/or hardware. No matter the manufacture, company or application.. lol please accept my apologies if this seems I’m being condescending or assholish or any other way out of line.. I most definitely am not.. it’s merely a way of logical thinking.. The Engineers way of thinking.. lol

Interesting. Didn't know you could do that on OBDII. Anyway, I use a scanner, so I won't run the risk of shorting out the DLC by choosing the wrong pins. Seriously, you can get a cheap scanner to pull, display and clear codes for well under $50.

I just did a review on this one:

If you are REAL curious to know what's going on in the CAN(HSCAN?) network(does that provoke?), you can get a OBD-II scan tool on Amazon that is equipped with a switch for both serial networks in FoMoCo products. Less than $20, delivered to your door(Mailbox), with USB connection for use with a PC or laptop.
Forscan software is available free of charge from forscan.org, and you'll be off to the races with enough left from a $20 bill to buy a soft-serve cone at the Flagpole in Rochester.
If the paperclip access mode is specified in the OBD-II spec(IEEE?), then it should work on FoMoCo vehicles as well as the ones you have used it on.

@tomw0: ForScan is what I normally use (with a cheap eBay ELM327). I did the review on the scanner I provided the link to, so I have that as well.
