Warning lights

I have just had 3 warning lights come up, al at once the TC, he ABS, and hill decent. I have a freelander 2003 TD4 auto, it started fine this morning, but while driving round a corner they came up. I have checked all fuses, sensors look fine and can’t physical see a break in the cable. Does anyone have any ideas on what this could be?

To know exactly what is causing the 3 amigos (that's what those lights are know as) will need a diagnostic read. The causes are many, so you can't really replace random components on the hope that you'll happen to change the component causing the issue first.
Having said that, the brake light switch is the most common item to fail, so you could change that on the off-chance that is the issue. If that doesn't fix it, it needs to be a diagnostic read I'm afraid.
