I've instaled a switch on the orange wire of the YAW sensor to disable the traction control, but when I turn it off my abs light turn on, and when i turn it on the abs light turn back off

any ideas ???

btw the car is a 2003.5 g35 coupe

 

VDC is incorporated with ABS. if you tamper(modify) the system, the light will come on showing that it is faulty

 

but will the abs still work??? there is a few thread saying that disconecting the yaw sensor disable the traction control but keep the abs
the vdc and slip light will stay on but the abs is not suposed to light up
but if the abs light is on does it necessarily mean that the abs is not working???
