Hi! I've got a 2004 GX and when I engage my center locker no VSC or traction control lights come on. The locker engages fine and does what it's supposed to and I only bring this up because I think there's an overreaching issue with my brake sensor system as neither the ABS nor Atrac seem to work. I don't have any trouble codes or extra dash lights and everything from the outside looks okay as the wheel speed sensors are plugged in and there are no obvious fuses blown. I suspect the previous owner disconnected some sort of braking module as the VSC Trac and off lights don't even light up when you put the key in the on position. Looking for advice on where to start poking a multimeter and troubleshooting.
