hey guys i need some help with my 7. i was driving home friday night
when my 4w ABS light comes on and something starts humming. it has done this
before but usually stop s after like 20 min of doing it.except this time
it drained my battery.its comming from the back left module thingy if
your standing in front of the car. i checked my brake fluid its okay. i
dont know what to do. can you help me out?

 

Replace the relay for the ABS pump. It's inside the little plastic box on top of the pump. The ABS pump is the "back left module thingy" with all the steel brake lines attached to it.

 

do I have to go to MAZDA for that? and how much might that run me?thanks

 

hey i unpluged it and pluged it back in while the battery was disconected and that seemed to work...should i replace it anyway?
