DSC/ABS/No Cruise No Speedo

I have a 2004 XK8 with 64,000 miles. I love this car. I drive it as often as possible as long as there's no salt on the road. The unusually long, cold winter meant she lay dormant for awhile. Battery was 95% dead. Charged it and it started right up. Runs like always except for:
1.) check engine light
2.) ABS light
3.) no cruise/instant fuel/trip odometer
4.) BRAKE light
5.) low brake fluid warning
6.) DSC not working
7.) red and yellow, elliptical lights, mid cluster
8.) no speedometer
Bought an OBDII reader.
Codes P1000 and P1637
Did a hard reset.
Bought a new, vented battery. Hard reset. No change.
Was able to clear the CEL.
Plan to clean wheel rotation sensors when I have time.
Have searched and read all I can in the forum.
Any suggestions?
Thanks in advance.
BTW, the airbag fault light was on before and is now off. Go figure.

Thanks RJ. I was hoping Jaguar had found a fix by 2004, but I guess not. Considering the only non-routine work performed on this car, since New, was the transmission pan gasket, the convertible pump repair and the airbag fault from a loose connector, I shouldn't be upset. With a team of owners as there are here in the forum, things don't seem quite as insurmountable.
True to form, any time estimate for my shade tree wrenching, needs to be multiplied by a factor of three. Time estimate to clean the sensors? One hour. Actual time? Three hours. This time, the factory lug wrench caved to my torquing ability, twisting it like a pretzel at the fair. Looked brand new too, never had the foam jack holder, from under the spare out till today. Better in the driveway than on the freeway, I guess.

I ran across this when I did the ABS solder job on my car. I accidentally messed up the chip trying to open the unit to solder the joints (cut to deep). Lost my speedo and all kinds of controls that apparently runs through the ABS module.
I'm thinking your whole module is toast not just the solder connections. I was able to purchase a replacement unit out of Florida for $350.00 with the module and pump motor so it was an easy swap.
A few year later I was getting the ABS TRAC/STAB Fault on the replacement and repaired the solder joints using the 7/8 Hole method over the solder area only. That worked much better for me. Mine's a 97 so I don't know if they moved the spedo controls on later units.

Did you inspect the wiring to the sensors? They are known to become frayed or broken. Either one can cause the ABS fault.

I bought an X-lug wrench to keep in the trunk along with a deep socket to go on my torque wrench.
I looked at the ABS unit tonight to see how much work it would take to wiggle it out. Looks like a project for the next day off. The holesaw technique looks doable. I too look at these projects realistically. "There's no good, working part I can't ruin attempting to repair it."
Yes, I took a good look at the wires, boots and rubber bushings for all four sensors. Really, the thing that impresses me most about this project is just how clean and rust free the entire chassis is. No wear, whatsoever in the wires, but an excellent suggestion all the same.

I should have sent this earlier. The resistance across the pins should be 1000-1100 ohm. Remove the neg. battery cable before disconnecting the cable from the module.

Did not realize there was that much difference. I believe the JTIS covers up to 04, and the electrical schematic can be traced, but a lot f work if you're not familiar with tracing circuits.
If the pins on your plug are numbered, you may find them to be the same for the wheel sensors.
Some one with experience of the 4.2 may be able to help.

Thanks for the advice. I can't find any numbering on the plug.
