ABS module Puzzle: Cruise Control non-op but Speedo fully functioning and accurate

[stephen newberg]

Eric is a really good guy. You should contact him via private email and discuss it, but I suspect that he would be willing to take the part back if it will not fit. But you need to get it organized with him ahead of time so everyone is on the same page.

These are out of a 99 you can def change just the control module I couldn't do it in my car because the bolts were seized and soft. I put a dab of anti seize on the bolts of the new so i can remove the module eaisly the next time. you can see i removed the snot like goo for soldering. altogether 6 wires were disconnected. One thing I will say tho is with my new module I unplugged and the car would not shift out of first. even tho my old one had many wires dc'd the car still shifted.

Thanks, you're the second person that I rode here saying that it was wrong electrical connections at this precise place. Maybe connections can be repaired with a small welding gun ?

Im pretty confident it's just those fine wire solder joints that came disconnected and you'd be fine to re solder them. between the immense heat and vibration these engine compartments produce I'd imagine these little solder points. get brittle.

Im not sure how to solder them and what core to use tho. they may have not used your typical hobby solder gun to solder it obviously. because its 2 different metals.

remember this as you fly over bumpy roads

Thanks to 99sho-time, we now have the ABS pump part # for 98-99 !
F6DZ-2C286-BA : 96-97 SHO only ABS module
F8DC-2C346-BB : 98-99 SHO only ABS module

Starting with F8DC, the number indicate that this part is for 98 year too (as the part is specific to SHO cars).

This confirm the fact that 96-97 and 98-99 are differents (like almost all the rest of the car). Making searches at store will be easier with this.

99-sho time:

WOW! Thanks for the pics! I am a little confused (so what's new?)...are the delicate wires that need resoldering the ones I highlighted in yellow ovals? I could only see 5 in the picture. I think I read somewhere that there should be 6?

 

[99sho-time]

3rd ,5th and 6th one to the left in the goo is bad and all 3 your circled on the right are all bad. the upper one towards the middle right is bad.
I must be ******** cause actually 7 not 6 were unsoldered my apologizes

 

[GEN 3 SHO FAN]

As a comparative, here is another broken one (don't remember where I took it... the one of 99sho-time ?). Not sure which year is tough...



It seems that each small "golden squares" with a dot in the middle had a small wire on it OMHA. Vibrations may have cut these small contacts. Sadly, we don't have photo to see where these small wires start (to have an idea to repair them).

The presence of goo is normal from factory ?

Qshiplvr, as we dug a lot into ABS module, it will be usefull to rename (or add) ABS module somewhere into the title of this thread. (As the title will be more explicit, others owners can come to give additionnals infos/photos.)

 

[99sho-time]

Yes that is mine. The goo is some sort of magnetic gel not sure what the actual purpose of it is.

 

[Qshiplvr]

OK I added "ABS Module" to the title. So just kinda wondering, did anyone ever submit their broken ABS module to the rebuilder or reman company to be fixed or reconditioned?

 

[stephen newberg]

I have not heard of anyone doing so. If you do hear, you might let us all know who did the rebuilding.

[GEN 3 SHO FAN]

Thanks for the add, maybe someone else have others infos to share.

I tough the goo was for preventing corrosion on the contacts...

I never rode something about ABS rebuilt too nor here or on V8SHO. But I think an experienced welder can do something with that, no ? (I'm talking about someone who weld computer parts, not car or industrial parts here.) The Ford blue books aren't very precise for the internal physic of this module.

However Qshiplvr, in your case as the cruise isn't fonctionning but speedo is o.k., did you think about checking the brake pedal switch (black plastic) ? It's linked to the ECM and cruise control (it put it off when you touch the brake), I had a trouble with it in the past on my SLO because corrosion starts with the water we have on the feet. It's very easy to check/replace. (I talk of it because your speedo if working, you can have 2 separate problems and this switch have no code IIRC.) This switch is all the same on Taurus and easy to find a good one used (brake pedal stop light switch # 13480).

I know that because I have to add a cruise control on one SLO which was coming without and I added it first without this switch. The cruise won't turn on until I put this switch on the pedal. This SLO with a AX4S was running without, then the ECM seems to don't needs this signal for anything else but on SHO, this signal is used for other things. In the next pages of the same book, in the transmission section, it's indicated that the signal of this switch is used for the transmission... May be usefull to check it as you have hard shifts.

Stephen: I saw in another post titled: "rebuild ABS module 1999 SHO" another user, Centrallaw from Tampa, FL posted: "Solder Terminals From Circuit Board
Just fixed control module ourselves by resoldering thread-size wires from circuit board to plug inside control module."

Gen 3 SHO Fan: When I was first trying to troubleshoot the problem, I had a buddy of mine check under my dash for that switch issue, and he said it "looked OK" but didn't actually test the switch electrically to see if it made/broke contact. I think you may be on to something there.

When you replace the swtich, is it connected with a Molex connector (i.e. factory plug) or do I need to cut/crimp or solder the switch when I replace it?

 

[GEN 3 SHO FAN]

It's been a long time, but the switch has a factory plug. However, as I talk about that now, I remembered how the one I repaired had broke. This switch on the brake pedal move with it and the wire, even if it's long enough, broke because it twisted always at the same place (before the molex, a little bit higher). The wire wasn't completely cut because plastic keep the 2 ends together (but had a strange curve in it).

Check :
1) the wire attentively, this wire is subject to be hooked by a foot too (in this case, you have to cut /crimp)
2) corrosion into the molex.
3) corrosion into the switch itself (small black and square plastic box a little bit higher than the pedal), it's like a 1 bolt job

In my case it failed a visual inspection (1). I think it's good to have a spare of this switch (and his wire) after 135-150k anyway.

You talked about a link to rebuilt an ABS. Seems interesting, and the company still exist.

So one other thing is puzzling me...When I performed the static CC flash test, the green "CRUISE" light flashed 4 times. Would a faulty brake pedal switch give this static error code? I think I remember seeing the first result is "Circuitry" and the second entry is ABS Control Module. Would this faulty brake pedal switch qualify as "circuitry?"

 

[Qshiplvr]

Here is the ABS flash code error key

 

[GEN 3 SHO FAN]

Where did you find that ? (I searched in the Ford book and seems not there.)

It's seems that the brake switch will throw a flash code 2 ("brake pedal position BPP switch"). Are you sure isn't 2 codes #2 ? Code #4 is pointing mostly at ABS module... "Circuitry" and "speed control servo" appears always together in each cases, it's probably ABS module internals.

At this point, it's outstanding my own knowledge. (Maybe someone repaired a lot of them as E1, SHOZ123 or Kirk Doucette can answer you). Sadly, we don't have the end of the story about the guy who wants to repair his own in 2009 but it was back in 2011 searching someone to do it (the repair wasn't reliable ?)

For info about ABS module, refering to my book, it's said (page 06-09-2) :

"Electrical system

Power is provided to the anti-lock brake module (2C219) through three separate fused lines for electronic logic control, hydrolic pump motor and solenoid valves. (...)

Signal inputs to the anti-lock brake module are :
- battery positive voltage (B+)
- front and rear anti-lock sensors wheel speed signals
- stoplight switch brake on/off signal
- diagnostic data link "

But for the cost, it worth the try, this part cost new 5-10$. Maybe 2-3$ at scrapyard (any Taurus with ABS) as we are not sure it's that. (Did you inspect it at least ?)

The .gif image I posted decoding the flashes from "CRUISE" light came from the following link:

http://www.v8sho.com/SHO/IntermittentCruiseControl.htm

It is one of the groups of images posted by user "U.L." I think this person went by "Uncle Lars"???

 

[Qshiplvr]

My problem is I am flying blind. I need to find the service manual for the 1999 SHO/Taurus but every time I search online, it seems that they are going for (used) $160 or so. I don't know if they have pages torn out or what, but I am hesitant to pay that for a very large set of books that I can't verify as complete.
