The pulse module has NOTHING to do with those lights. The Steering angle sensor sure does, but I gotta tell you, in fourteen years of ownership, I do not think ANYONE has replaced the SAS and seen the lights go out as a result.

I do not know for sure what your issue is, you might consider starting your own, new thread and many of us here will work thru it with you. There is nothing wrong with starting your own thread for a problem, and I see the other guy had a lot of parts replaced that have nothing to do with those lights. This is not an engine problem, and out of the parts he changed, the RCM would be the most likely item.

One thing to ask is this: If your car is an automatic, do you have issues getting it out of "park"?
Also, does the speedometer work properly?

The answer to these questions can help isolate where, in the stability/traction control system, things are failing. I prefer to try to understand, logically, what is going on, and not just throw commonly-failed parts at the car.
