Code C1185

Hi, I have a friends 2000 Windstar with a C1185 code. I understand the ABS control module may need to be replaced. In the repair manual it indicates I must follow the instructions below. Has anyone else done this? Do I require a GM Tech tool?

CAUTION: Prior to removal of module, it is necessary to upload module configuration information to the scan tool. This information needs to be downloaded into the new module once installed. For additional information, refer to Section 418-01

I replaced the electronics portion of the ABS module in '00 Windstar without uploading configuration information from the old module (which was dead; it probably couldn't provide any info anyway). I believe this step is related to saving the "learned" data from the original module. However, the new module is perfectly capable of learning on its own (which is what the original module did in the first place).

See pics of my ABS module replacement project here:

I've included helpful notes with many of the pictures, which appear beneath the picture.

Note that it is possible to replace the electronic portion of the ABS module *without* replacing the hydraulic portion. This requires separating the two while attached to the vehicle - which may be nearly impossible if there's lots of corrosion on the underside of your van.

I performed this fix back in late 2007 - and the ABS on my van still works fine.

The Usual Disclaimer: I did this work on my van and it worked well for me; it might not work for you. If you aren't familiar with safely working on the underside of a vehicle, learn how to do so before hurting yourself or someone else.

P.S. For other researching Windstar ABS issues: While the module is a common failure point of Windstars of this era, ABS problems can be caused by sensor and connector problems. Here are some pics of my ABS sensor and connector cleaning and checking project:

Awesome, thanks for the links on your how to.

Phil-
I just came across you post on the C1185 issue. Mine just came on, by itelf, no other codes. It did erase and did not come back on yet. I tried the link you supplied for the repair. The link goes to a photo site that no longer shares. Do you have the write up and pictures available elsewhere? I'd appreciate it!

Thanks
Wayne

Yeah, Webshots basically went out of business a while back, trashing my albums.

I've re-posted my ABS project pictures here:

Warning: The Webshots shutdown also lost the order of the pictures as I had posted them originally - and trashed the text I had in the original album. My apologies if it's hard to follow.

Note that you'll see pictures of another Windstar ABS unit: I bought a used unit off eBay - which was already bad. However, it didn't cost that much - and taking it apart gave me the confidence to tackle the one on my van. I was able to remove the electronic portion of the ABS module *without* breaking into the hydraulic lines (which vastly complicates the project). The van is still drivable with the ABS electronics removed (of course, without ABS function).

Today, there are other options available that didn't exist during my Windstar ABS project. There are services that can repair Windstar ABS modules (I replaced mine with a new Ford OEM unit). Start your learning process by going to eBay and searching on "windstar abs repair".

The good news: At 170K-ish miles, my Windstar ABS still works fine since that repair project, 6+ years ago.

Thank you for the pics. I've seen the ones on Ebay. Many want you to send yours in. If I know the parts needed, I can do myself, just need direction on what.

Just went through the pictures. Not in order, but not a big deal. I had to re-read your post. I now "see" that you were doing a replacement, not a repair or rebuild of the unit. I was thinking you knew what parts to replace...and so on... Still a good job on the pics and placement. Thanks.

Yes, I replaced the electronic portion of my module with a new module.

I've heard of people who have repaired their own modules - but I never found specific, accurate information on exactly what has to be done to a Windstar module. You'll see that I did cut my bad eBay module apart, just to get a closer look a the printed circuit board. I didn't see anything obvious (cracked solder joints, etc.) that would have caused a problem. Obviously, the repair services do know what to look for; they've done it many times and have the correct equipment.

I repaired mine. The big solder joint in the middle is probably cold (cracked.) Look very carefully.

I desoldered and re-soldered all the ones that could be done with my $10 radio shack soldering iron. I covered them all with conformal coating to try and seal them better. I then finished with plastic 2-part epoxy to glue the top back on.

I haven't seen the abs light in 4 years now and counting.

Scubacat: Can you identify approximately where you re-soldered the joint in this picture of my dead eBay brake module?

I no longer have my original brake module. Interestingly, my new-from-Ford module include a core charge; I had to ship the old one back.

Thanks!

I heated all the bigger ones that were capable of being serviced with a hand-held solder iron.

I'm sorry to report, though, that the repair lasted about 4 years. I'm resurrecting this thread just to share that sad news. As of 2 nights ago, the ABS light is back on with a full set of 13 ABS codes I pulled from the scanner which means the module has failed again. I'm thinking that a more professional rebuilding service is in order now.

I'm glad to know you don't need a dealer to re-flash anything. I have another module I grabbed from a junk yard some time ago that I'm going to have rebuilt by someone who really knows what they're doing (and will guarantee it) and then I'll swap it in when the snow melts and I can feel my face outside again. I really miss those Atlanta winters without all this mess!!

Sorry to hear that your module failed again.

Yes, I suspect the module repair businesses have this down to a very-repeatable science - and are very reasonably priced these days.

As long as your junkyard module came from a compatible Windstar model, it should work without reprogramming concerns. That said, my experience in this arena came via a new OEM module, so I didn't quite have the same situation you do.

My module is still working fine and continues in daily service at 180K-ish miles.

Let us know how your module replacement works out!

I'm wondering what could even be "programmed"? I didn't even see any flash memory on the board when I looked (albeit not too carefully). I think it's just an excuse to gouge people for more labor when you're at the dealer. What is it that could even be "learned" anyway?

Craziness.

I have replaced this controller twice over the years on my '99. The first time I was not required to provide a core, but the second time I was. Next time around, if there is a next time, I intend to give this outfit a contact as they have helped me with electronics on other brands:
