| Re: What does SDM stand for? Thanks to everyone for there inputs. All of the information was very helpful. Per the responses I also have a U1000C code and the air bag light on the dash is on all of the time. I pulled the passenger seat and there is nothing under it except for the carpet. I also checked under the carpet and did not find anything. Are there any detailed instructions on the site that will show me how to get at the device under the center console? My CTS is an Automatic if that makes any difference. |
