abs and handbrake light flashing -problem with my 02 wrx i

[ramsamooj]

hey guys ,I dont know if anyone of you all ever experience this problem but my abs and handbrake light on my dash come on and go off at period intervals.Whenever this happens my turbo timer starts blinking and sometimes my radio, the speedometer drops down to zero and then back to the normal speed.Is as if the car cuts off and comes on back.

Any advice

sounds like a bad/loose ground.

check the battery terminals, and other main wiring for loose connections.
