Hi, I need help. I have 2005 G35x and I think the ABS pump went bad. What happened.....when you drive on highway 65-75 MPH then you slow done, hit the brake, the whole car start shaking like the rotors are bad. I put new rotors, but the problem is still there. Then you stop, start the car again and car drive normaly. After few miles..same problem again. So I think the ABS pump or ABS computer is bad.
Now...is possible, the problem is really ABS pump? And if, anyone has idea where to send tha pump to fix it? Anyone had same problem?
Thanks a lot to help me with this problem.

 

Odd. No error codes?

 

Pull the ABS fuse and drive it to see if the problem goes away.

 

I do not have a scanner, so have no idea if any erros codes are on. But no check engine light.
The fuse is together with the main fuse. So is unpossible to take the fuse out. But I may be mistaken.

 

What "main" fuse?
You can pull the ABS fuse. I have done it many times before. It will kill the ABS and traction control.

 

Ok, the fuse is together with ignition switch.(not a main) Is a big fuse....3 in 1.

 

I cut off the two 30AMPs for ABS. I drive the car, but the problem is still there. What else could be?

 

Perhaps some of your suspension bushings are really bad. Or a bad wheel bearing?

 

This problem is with the brakes, I don't know what...but 100% brakes problem. I checked complete suspension, I did change front swaybar links, and all around is good. Wheel bearings are good too. They don't makes any noises.

 

my abs does the same thing. i think it might be a bad controller.. I dunno either though... makes me crazy

 

ABS control unit? You think, the control unit is bolt to the ABS pump? Or somewhere else? Makes me crazy too...

 

When you got new rotors, did you get new pads too? Still sounds more like a problem with the rotors or pads to me.
