DSC System on 2000 Jaguar S-Type

I am getting a DSC System On/Off or Fault that intermittantly comes on. It causes strange things like the radio/clock display goes dead or the miles display goes dead.
I am parked now and the car won't even start now.

Dear DonEmLinda,

Your Jag has several computers that need to be scanned to properly determine the 'root' cause of your problem. I would ask around for a good shop who knows how to diagnose modern Jags and tow your car to them. I recommend this because there are so many things/systems that could be causing your problems. Best of Luck!

The Jags computers basically will reduce performance or not let you turn on the car at all to prevent damage or safety issue. All you might have wrong is a plain speed sensor on the wheel.
