This is coincidental, my car did exactly the same thing with exactly the same indications. That's where the similarity ends of course because my car is a Daihatsu Sirion 1.5sx - and before anyone laughs it has ABS and VSC.
Anyway - I replaced a rear bearing hub, which has an integral ABS sender on it. I buttoned it all up and voila! I had the ABS, VSC, and the handbrake warning illuminate. I was a bit shocked because the job is only four bolts and an electric plug, and the other side I did the previous week gave no problems. So I pulled it all out and checked the resistance of the ABS unit against the old one and there was no resistance - it was apparent my new hub unit had a duff ABS sender.
I did fix it by swapping the old sender onto the new bearing assembly but to my horror the dash lights still stayed on. After much thinking I drove the car and after a hundred yards the light extinguished. It seemed the ECU needed to have a "think" about things. All is well after many miles.
I am still puzzling over why the handbrake light warning came on though.
Summing up it may just be a dead sender on this Jag and the only way to find out is check them by resistance (if you know what value it should be), or get a computer plugged into to interrogate the brake ECU. If it isn't a dead sender unit I would lose interest in this Jag.
Good luck. Regards.
