ABS/traction light problem

**johnfdavids** · 09-18-2013

Hi All,

I am new to GPF.net and I am looking for an answer to a problem I've been trying to fix. I have a 2004 Pontiac grand Prix GT1, non supercharged. The problem I am having is that the ABS and traction control light are on and won't go off. I have had it scanned for codes, and the ABS code I am getting is C0121 Valve Relay Circuit Malfunction. I have searched this site, and don't see any posts relating to this code. Can someone please help? I don't really know where to start. There doesn't seem to be a whole lot on the net about this issue.

Thanks in advance!

hub, check all your wires that go into the hub, one might be disconnected

Check all fuses under the hood to make sure none are blown. The code can mean voltage isn't present at a certain point in the system, a relay in the module I believe.

Thanks to all for posting. I previously checked the fuses and apparently I hadn't checked all of them. There are a total of three fuses under the hood, in the fuse box. The one tittled "ABS SOL", which I assume stands for abs solenoid, was blown. Replaced it and light went off right away. Hope this post helps anyone else that may experience the same issue. Thanks again!
