Question: How to check if i have ABS

[SaxoCup16v]

I have a citroen saxo vts (or CUP in Portugal), and i was wondering if i may a broken ABS, since vts here have the abs and mine simply locks the wheels

2 ports on the master cylinder it's ABS,4 ports no ABS.

Ah, sorry for the delay, the car was not with me, i just verified, it has indeed 4 ports, too bad i guess, hard to maximize braking in a emergency high speed corner brake :/ inside wheel sometimes lock and i have to let go a bit because of instability

If car has ABS --then there will be a wraning light on dash --which sould come on when ignition is switched on and then go off at starting --if you have abs fault it will be on all the time
