ABS/ASC problem has me stuck

Good luck.

Using a procedure posted on another forum a few years ago by a long-suffering XK8 owner named Jeff Cline, I was able to remove the module without disconnecting brake lines. This is Jeff's description ...
Removal Instructions
On my 1997 XK8, the ABS module can be removed from the pump without disconnecting lines, but you have to do this:
1) Disconnect the battery
2) Remove windshield washer filler neck by twisting 90 degrees and removing
3) Unbolt the ABS pump bracket from the inner fender
4) Disconnect the 2 wiring harnesses from the ABS module
5) Remove the 4 small bolts from the ABS electronic module. You can use a small metric 6 point socket but I don't remember what size
6) Grab the bottom of the pump assembly, and torque the bottom towards the engine. This opens the gap between the pump and the outer lines, allowing the ABS module to slide off of the pistons and drop down out of the way
7) Fish the ABS module out of the tangle of lines by opening the gap between 2 of the lines and snaking the module out.
The first time I removed the module it wasn't easy. The second time I removed it, it took less than 10 minutes.
I think I may have driven the car with the module out, but not sure anymore. (This is often the case with things that happened more than 15 minutes ago.)

Are you sure you can drive the car with the ABS module removed? This might help http://jagrepair.com/images/AutoRepa...aul%20Bush.pdf

OK, after much research, great suggestions from everyone on the forum and a backup plan courtesy of Motorcarman from Decatur, I have decided to bite the bullet and attempt the ABS module fix.
I will save this great adventure for the weekend, but will update everyone with the results when I'm done.
So wish me luck.

Well, I thought I would update everyone. Pulled the ABS module using the fine instructions found thru the forum and opened it up. One connection was cracked all the way around and the second connection was starting to crack. Put new solder on both, RTV'd the box and let sit overnight snug in my vise.
Reinstalled this morning and no ABS/Trac light! Amazing! Did a quick test drive to warmup condition and all seems to be well. I still need to bleed the brakes, they are a little spongy now.
A few notes for anyone who is considering attempting this...it is indeed a very doable DIY project. It requires minimal handyman skills, lots of patience and remembering not to force anything (lines to ABS?). For XK8 owners the illustrations from jag-lovers.org must be an early model or possibly an XJ. To refit the windshield washer filler, I had to go up thru the wheel well access panel to hold the filler neck in place. Also be careful with the hydraulic line separator guides. They become brittle and break easily.
Lastly I must thank this forum for all the help and encouragement. Special kudos to H20boy for the diagnostics help and to motorcarman for a very helpful explanation of some concerns I had, not to mention convincing me to do it at all. Very much appreciated. Thanks guys.
Now to see if the Low Coolant light comes back or not.

I drilled a 5/8" hole just above the terminals on mine using a drill press. With a drill press you can control the depth of the cut. I was then able to solder both terminals only one was cracked. and plug it with a black plastic plug. total time removing, soldering and reinstalling about one and a half hours. Drilling the hole was less invasive than cutting the module.

My attempt to do the solder repair failed. I noticed on the back side of the module what appears to be some kind of leak. It is a yellow foam looking substance. Any ideas what it is?
I called Module Masters to see if they could confirm my suspicion but they only told me to send it to them. They said if they couldn't repair it I would only be out the shipping.

Not an electrical genius, but I did work in a Radio/TV repair shop when I was in high school (they actually repaired TVs then). Anything that looks like a leak or something like watery foam is bad. Something has likely fried itself. Transistor, resistor, or some such. Bet if you look around, one of the small electrical bits has a distorted shape.
There are some EE's on this forum that can do better at an explanation, but something got too hot. May still be fixable though, so probably worth sending off for repair.

OK - so I should have read the rest of the thread, - most part deleted, but FWIW - I did not trust me to do the repair, and I have soldered Boards in the past, I found a place in CA that did it for $55 - plus cost of shipping the unit to them - shipped it on a Monday, had it back by Saturday - ABS/ASC problem fixed!
