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!
