Security, ABS light and Brake light on! Please help!

[V12Alp]

Hi guys, I have a problem here, also it's kind of weird. When I start the car and put it right away on drive (start moving right away) I here a sound, literally explaining like "ghhh" then right away anti-lock and brake lights simultaniously turn on. Also, if I start the car and wait few seconds after putting it on drive(no moving but holding the brake pedal) no light turns on, but while driving I might get the ABS light on. Another thing is when I hit a bump or pad hole on the road or corner at let's say 35 security light goes off. Can anyone please tell me what the problem might be? Thank you,

What year? Sounds like a loose connection. Check all grounds and plugs. Get a wiring diagram from your liberary and check out what wires would power those items.

The security light is a seperate issue. You could have a tech check the VATS system for the car to solve that problem, However if the car functions with the security light on then it's no immediate cause for concern. The other lights on the other hand sounds like a multiple part problem. First thing to do is chekc the brakes and make sure,you are not running metal to metal and to clean out any brake dust. Second, have the wheel bearings in the front checked to see if the noise is coming from there. Keep in mind that the ABS sensor is normally located in the assembly. Look at the abs connections to make sure the plugs aren't fouled cracked or burned out. Laslty look for fluid leakage from the wheel cylinders calipers and lines.
