Anyone have any experience with ABS module failure?

Valentine wants to charge $1000 parts + labour for the job that I have heard is 4 screws and less than $150 to fix?

I find it odd that I just had the throttle sensor reprogrammed (recall 155) and the very next day I have this failure? Anyone heard of any coincidence in this?

My god, I am cute... but not stupid!!!!

World pac lists the abs (with TRACS) control unit at $724.43. Says it may need reprogramming (Andy?).

There's an aftermarket remanufactured one for $197 though...

ABS module failure is a fairly common problem (most say it's inevitable for '96+), but apparently it's a simple repair to fix. (not according to the quote below, tho)

From Bay 13 on Volvospeed:

"On the 1996 and newer ABS systems the ABS module is bolted to the bottom of the hydraulic/pump block. The most common codes that are set in the module is for the wheel sensors or the ABS pump. In most all cases the sensors check out just fine and the pump can be activated and it runs fine. You could have the codes cleared and things will be fine for a while then the light is back on again. When you start your car and then get up to about 20 MPH a very quick test of the pump is conducted, if the pump doesnt run, the light will turn on. The next time you start your car everything works and the light could be turned off. The problem is that in time small hairline cracks could show up on the circuit board of the module causing intermittent signal loss, thus causing a code to be set and the light to come on."

I've also seen something about it being one particular part (diode, resistor, something else?) that needs to get replaced, rather than a cracked circuit board.

Someone did a little digging and found this link...

I am thinking it is a way better option than the $1500 route. Any experience / comments on this?

My goodness, if a mother of 4 can take care of this, I surely can!!

I've seen so many of these failures. And its not just an early problem. Its continued into the S80's, but around 03 it was fixed.

Here is what we do in the shop on our "personal cars".

Remove module

Check over every pin connector on the circuit board with a magnifying glass.

What happens is the soldier shrinks and looses contact with diodes and other circuitry on the board. A little warmth, some soldier, and you have a working ABS module.

I've only seen this not work on probably 2 cars. Length varies, sometimes they go years without the problems reoccuring, othertimes shorter.

So basically the same fix as the old K-jet fuel pump relay? Shewt, Athal's a pro at fixing that!

So far, sofa king good?

Damn those modules are a pain to get apart. Only managed to jab myself with the drewscriver once...

Only drove it home... and it was good.

Response is definitely better, but looks like we got good weather for the next bit, so we may not know for some time.

Cheers though buddy... you'll be the first to hear of any failure!!!

I take it you tried soldiering the joints?

Did you see any visibly split with a magnifying glass?

I hope it works for you

Definitely could see some small cracks at a couple of the large pins (two pin connector) and at least I thought I could on the small ones. Not nearly as obvious as the 240 relays so you wonder how the 240 stuff actually works when the connectors actually wiggle on the board!

Well, that's goddam cool that all these ABS modules need is a reflow. I mean, a PITA because it's happening in the first place, but you don't sneeze at these kind of free fixes because they don't happen that often.

Shit we have so many customers that "upgrade" cars when these happen... Why spend 1000 dollars on a fix, when for 10K you can have yourself a nice newer car!
Gotta watch for them and fix/sell them. Work is kinda lame about that thing since they loose out on the money they bring at auction.
