Ford Ltd Crown Victoria diagnostics

As an example, I had that '83 Colony Park with EEC III/CFI, which was not OBD I. the next year, '84, which had EEC IV/CFI, was OBD I because the EPA tightened emissions standards for the '84 MY.

 

Its your money, but most OBD I are limited in what you can do anyways. Not all offer any type of data streaming. Frankly I've never needed it for OBD I anyway. I just don't think it is worth it to get a fancy scanner to use on older cars when you can't do much with the older cars anyway. I suppose if you are working on a bunch of 15+ y/o OBD II cars then it might be great. If I were in the market for a scanner I wouldn't even bother with this one since most of the cars I work on nowadays are max 8-10 years old. The scanner I have supports all OBD II cars.

 

thanks to all for your valuable input!

In most points, I totally agree with you.
as mentioned earlier, I wouldn´t think about buying a scanner for my Ford only. My Trans Sport definitely has OBDI and my hope is to get deep access to the ecm and other systems. From what I´ve heard, this is not possible with the low price scanner tools. Resetting or erasing failure codes, ok, but not digging into the system and getting detailed information or sensor readings. According to my information cheap scanners are not able to support you adequately in trobleshooting, only give you an idea what could be wrong.
OBDII currently is out of my scope as I only own one OBDII car.
Maybe it´s also a different situation between the U.S. and Germany. Here, it is very hard to find a shop that is capable of working on the older U.S. cars. Oh yes, there are a lot of dealers, and most of them provide a certain level of service, but not a shop you can trust. So, if you want to keep your old U.S. car running, and I WANT that, you are on your own.
I know for my trans sport there is the possibility to get access with an interface and a DOS computer. Unfortunately I neither have a DOS laptop nor the interface which is no longer available as they had been handmade by a member of the trans sport forum. They choose this alternative as the professional scanners are either too expensive or not available or both.
Anyway, if my Ford grants access to its system with this scanner and a specific cable (or OBDI), I could use it, no matter how much I can do.

 

When will you be getting the scan tool? I'd like to see a pic or two of it and the accessory connectors. An MT2500 will have cartridges to plug into the body, a single cable with standard parallel connectors, then connector 'heads' you attach on the cable to connect to the car's diagnostic connector. It should also have a separate power cable that plugs between the connector head and the cigar lighter to power the scan tool. And you should have a couple 9 volt batteries to power the scan tool before you hook it up. If you can take those pics, I can tell you if you're missing anything.

 

OK, I have both an OTC Monitor 2000 and a Matco 4000E which is made by OTC for Matco and is the later version. I have scanned the older manual and made it into a PDF file which should be attached. It should tell you what is available, diagnostic wise, for your car and also shows the adapter. Sorry it's sideways but it wouldn't fit in my scanner the other way. If you print it out and assemble it in landscape mode, it should read OK.

 

Anyone have any of the literature for the MT2500? Since I had to quit working, I don't have any access to those books anymore.

 

Thanks for the help! The pdf is VERY ok!
I will check my car for this Ford self-test connector. Seems that this could be the correct entrance to the car´s system.

I am not sure when exactly I buy it. If yes, then within short. In fact, due to the conversation here I am a bit confused. As far as I remember the case contained the tool itself and certain cartridges for U.S. cars covering up the big three up to year 2000 and some European makes. Right now, thinking about it, I am not sure if there were cables in the case or not. I will have to check with my sales person.

 

Just to be clear. Neither of my units came with the 2 wire Ford adapter they show, nor did I ever require it between 1984 and 2000. It may be that a vehicle that required it never came into my shop with problems. It may be that you will have to purchase it separately. One of my mechanics had the Snap On unit, but I don't recall what adapters he had with his.

 

I understand.
First of all I have to understand which one is the correct connector. Seems that your pdf gives me the perfect hint. Thanks for that!
Hopefully, I will never have this kind of problems too, but just to be prepared....when the car is down and you have to go out to search for the correct connector and have to buy cables and cartridges first...

 

Well, any of the Ford EEC IV systems, regardless of engine, will require both connectors I showed in that pic I posted; the small single-wire one is the Self-Test Input (STI) trigger connector. It is what starts the computer's self-test program. Try this diagram, if you go to do the Key On Engine Off (KOEO) test:

OK, here is a picture of my Ford adapter. It is a female and plugs into the pictures that Hobo is showing. It should be included with the Big 3 connectors that come with your unit. As I said before, this is the only adapter I ever used on Fords and had never seen the 2 wire one shown in the PDF that I posted.

That PDF was scanned from a manual that was printed in 1985. It may well be that it was an early adapter and the one I show below came out later. I believe it is a universal adapter that may have been introduced later. I think it will serve your purposed if it is included in the unit that you buy.

 

Wow!
thanks a lot for all the Information provided!
All of it is extremely useful. I did not check for this connector yet, it´s too cold outside...brrr...
but I will do within the next few days.
So when I got it right, I will not need a scanner to read out the failure codes on my crown vic. A regular test lamp is sufficient, so maybe I should give it a try.
Anyway, I will keep you updated about the scanner tool, as the offer is not too expensive, I believe it would be better have one instead of having none.... At least it may serve me well with my TS or the Windstar...

 

What year Windbag do you have?

 

Did you get one? I'd send you one for free,it is Ford-specific EEC IV and comes with the manual. It was useful on my '85-'86-'88-'89 Ford 5.0L wagons. I have it right here.
