Help! I have an 01' STS. I have had the car since new and in the last two weeks I have been getting a number of codes. Also the Service Stability System comes on whenever and I will be driving when the DIC reads Stability System Engaged and it will momentarily pull to one side or the other. Is that a Steering wheel position sensor? Here are all the current codes: C1246, PO386, PO410, PO420, PO463, PO741, P1860. What are the other codes and the remedy? Thanks!:banghead:

Your C1246 code is the only code that might even remotely apply to a SERVICE STABILTY SYSTEM message. And no, it is not the steering wheel position sensor.

C1246 - Brake Lining Wear Circuit Open
With this code present, you should also have a CHANGE BRAKE PADS message. Has there been recent brake work done on the car?

The remainder of your codes are all "P" (Powertrain) codes. I would clear all codes and do a short test drive to see which codes are set again.
