Hello: If there is a problem in the ABS it will bring on the tcs light as well. To determine what is causing the problem you need to have the ABS checked with a scanner to get the code. Then trouble shoot the components that the code leads you to. Normal braking is available with the light on but TCS is not as it relies on ABS for functioning the TCS.

lock brake system light comes up when there is issue with car brake systems. It

Whenever
this warning light or any other stays on in the dash it is indicating
that the systems control module (or the system sensor in the case of
lights like low oil pressure, door open indicators etc.) has detected
a fault, it then disables the system (this applies to ABS,TCS, TCM,
SRS and BCM faults and others) as long as the light is on. You must
now have the dealer hook up a special electronic diagnostic tool and
"scan" the system for the fault code that is stored for the
problem(s)
