ABS, TC lights on dash and break lights failing
 

I have a 2000 p38 range rover vogue 4.6 petrol/ lpg air suspension removed.
yesterday the abs and tc lights came up on dash with a beep saying EAS manual, breaks and traction seem fine also the break lights have stopped working all together i have checked all the fuses, relays and bulbs and cant see or smell anything wrong. This is my first land rover so am very new to this and was looking for some help before getting my pants pulled down and make a mechanics year! please help!
