Hello all,

I have an error code 43 that doesnt seem to be going away. The Traction control light stays solidly light.

I have done some research and there is one link here that cross references a bunch of others, but with no solid resolution to any:

Need some help chasing this one down. Any suggestions on what to check first?

I do hear the pump kick in when starting after 5 seconds of starting the car. Any ideas?

Bled the accumulator.

Same behavior, it appears the accumulator pump kicks in immediately after starting the car for a while, and then stops. After it stops the trac light comes on.

Anyone have any ideas on this?

Problem is identical to problem above.

Nearly 60 looks and no one else has a solution.

There are 4 plus threads on this with little or no closure to how they got solved.

Anyone?

Did you get your problem fixed yet? I just had my brake booster replaced, turns out the guy that installed the remote starter for the previous owner had drilled into the outer edge of the booster. This winter when I started the car the brake pedal was hard at first and I had never liked how the car stopped since I've owned it and so I've replaced eveything including steel lines and installed stainless flex hoses but to no avail. When I picked my car up Friday night after the booster was replaced my brakes were the best ever but the Trac light is now on. I'll let you know what I find out when I take it back if you want.

Here's an update on my trac light coming on. They did a complete brake fluid flush and it not only turned that light off it turned my "Tail Light Warning" light off as well.
