It's most likely a bad ABS control unit ($416 plus labor) BUT as for this advice:

"What usually fails is the solder in the pc board under the ABS block in the engine compartment; a shop repair runs $350 and up. In a recent post to the brickboard, a correspondent indicated he was able to make the repair himself. (How hard can it be? Use a de-soldering tool to remove old solder, then flow the new stuff in.)"


...........I don't know if I can believe that as I've read that before here and have personally opened a couple of these control units up (being replaced) to check. First of all, it's not made to be opened up so one must use a hacksaw (or other means) and cut it opened. Then.....the board is coated with a water proof rubber like gel that DOES NOT come off with ease. Next.....IF anyone else has actually seen one of these, we're talking a VERY small circuit board with VERY SMALL solder lines and no solder iron that I own (and I own several btw) or have seen is small enough to even think about trying that. I don't know where one would purchase a soldering iron with a tip small enough BUT that brings me to my next point........WHERE exactly does one solder? It's not adviseable to just start laying down beads of solder on any circuit board w/o knowing what you're doing or why you're doing it. I have never seen what looks like "bad solder joints" when inspecting one of these and the original solder looks perfect (no cracks or burns).

When re-assembled, you'ld have to use an epoxy to re-assemble and it must be water proof again or it'll fail (if actually fixed).

Can anyone here verify that they've personally done this repair and add a few more specify details to my questions above? If not, it's my opinion that trying that is bad advice as I think it'll be a waste of time. The correct solution is to replace the control unit.
