Tcs light comes on while driving and will not go off
Try to disconnect the plug on your brake master cylinder. Start you car and see if the light turns off. If they do then replace the brake master cylinder
I assume tht is traction control. Check fuses ,eeven abs fuses ,traction control is part of abs. If fuses ok will need scan tool to find cause of lite going on. Most common are abs sensors and broken abs wires. And if abs tone ring is part of axle shaft some rock may have damaged teeth of ring .
