The ABS & SERV light along with the handbrake warning light were on with one ABS fault I had, but the last time only the ABS & SERV were on, I never had the stop light....maybe it depends on the fault...not sure.
Anyway you obviously have a ABS fault of some sort, the brakes will still operate normally just with no ABS function.
You need to start somewhere to find the fault so the first place to start is the fuse boxes...check the fuses, even if the fuse is ok make sure you remove it and re seat it just in case it's making a bad connection.... unlikely but you can't overlook anything! There is also a fuse box in the engine compartment beside the battery.
If the fuses are ok you then need to have the fault diagnosed at a garage by having the car plugged in or you could try to test the 4 wheel speed sensors using the method posted by voxmagna POST # 23 HERE
Bear in mind that voxmagna was testing for a defective magnetic wheel bearing so you can skip some of the steps in the procedure, just concentrate on connecting to the sensors to see if you get a reading from each one when you spin the wheel.
See how you get on with that lot first...then post back.
