| Re: What does SDM stand for?
SI points to the SDM needing to be replaced. If you also have a U1000 code I would plan on replacing the SDM. If you do NOT have a U1000 code, it most likely the Sensor Asm-Inflatable Restraint Front End. This is just what I read in SI, I would definitely take it in to your local dealer to have it properly diagnosed. It could need either part or both. The U1088 appears to be an OnStar code, any code that starts with Uxxxx is a communication error code. Typically loss of communication with the effected module or sensor. |
