I recently purchased a 2019 Z06 3LZ from an insurance auction. It was damaged in the right front wheel area but thankfully there was no frame damage. The steering wheel airbag was blown along with both sets of seat belts and the pre-tensioners. Everything I had read indicated that the SDM module would have to be either replaced or sent off to a company that resets these modules. So acting on that information, I went through the trouble of removing the module assuming that I would send it off for a reset. Thankfully, I didn't do that. I replaced the driver airbag and saved the clock spring by replacing the melted connectors that plug into the airbag. The seatbelts and tensioners were replaced (bought new ones). For the heck of it, I decided to plug the module back in just to see if it would recognize that the new parts fixed all of the stored codes.I have anAutel MS906BTscan tool and I turned on the accessory function to connect with the system. After checking the codes, it showed that all of the previous restraint codes were not current on this ignition cycle. That was good news but of course the airbag light on the dash was still on. I decided to clear the codes and the dash airbag light went out and no fault codes were found. Disbelieving what just happened, I turned off the ignition and then went through the process again only to find that in fact, all restraint codes were gone and there was no airbag light on the dash.

So unless something happens when I start the car (I am still repairing damage including the oil tank so I can't start the car yet) or there is something that I don't know about or understand, it appears that you can clear the codes from the SDM (at least on this model year) and that you don't have to go through the expense of replacing or sending out the module for reset.

Thanks for his posting. Should be helpful to some folks down the road.
