S70 ABS module defeat?

[mkr5000]

I've had that faulty PC board problem with my 98 S70 for a while.

Is there any way I can simply defeat the ABS module by undoing aor taking out a fuse or something rather than the constant switching back and forth.

Obviously, you can drive the car without ABS apparently.

Also, I've seen some photos on taking that module out for a rebuild....how difficult is it getting it out?

THANKS

Those modules are known for their bad soldering. It shouldn't be too difficult to repair this yourself if you know how to solder.

Try to google a bit for more information.

Good luck!

It's pretty easy to repair the module, certainly less work than trying to disable it.

Electronics is my business -- so that's good. I've seen some web instructions on getting it out but just looking at it it seems awful cramped in there (and the bolts are hard to see -- facing downwards?).

I'll get it out....any tips?

I'd buy a rebuilt one off Ebay but apparently I have an odd part number that isn't stocked.

I have the T5.

Hi,

I've just finished repairing the module from my '96 850, and electronics is also my business. Have a look at http://www.matthewsvolvosite.com/chat/phpBB2/viewtopic.php?p=46827#46827 if you already haven't.

Removing the module on my car (right hand drive non-turbo) took less than 15minutes. Access was good. I also had a set of Torx sockets. Removing the 4 "one-way" spring clips on the module case was not too difficult, but opening the case took me at least an hour. I was trying to not damage it. I used a piece of flat spring steel about 2mm wide, bent at 90degrees to scrape as much silicone as I could from the groove, then some brute force and leverage.

Inside the PCB is coated with a thick silicone-like conformal coating. I had to peel it off the socket pins to get a good look at them. The pins for the two pin connector were obviously fractured (after the coating was removed). I cleaned the coating from all of the connector pins desoldered and then resoldered them, although I think only the two big ones needed it. I used clear nail polish to reseal the PCB, and a neutral cure silicone sealant (made by Selleys) to reseal the casing, used sparingly. Then after the case was back together I ran a bead around the gap, and smeared with my finger and wiped the excess with a rag dipped in mineral turpentine, to neaten it up. I put it back on the car almost straight away, but left it overnigh before starting. Although the tube says 72 hours to completely cure, a big blob I had left over seemed "solid" overnight.

Unit has worked fine ever since (about 5 days so far).

Thanks Barry -- looks pretty straightforward.

The electronics I can do in my sleep but I get frustrated with bolt positions and the access to these things....but I'll try it.
I'd be a piss poor mechanic.

No patience.

How can you be involved in electronics and not have patience )
