Default SDM NO COMM help

Im getting an SDM NO COMM message when I pull codes on my DIC. I did an HUD conversion on the car and used a cluster out of an 03. Also added the memory package with sport seats out of the same car. Airbag light comes on at startup, then goes off like it should. Do I even have a problem, or am I driving without a working airbag?

Thanks-97C5

SDM no comm is normal. Its another module that they added into the car after 97. so your can doesnt have it. Hence, no communication.

As i recall, you also had to move the AIRBAG light (meaning you had to take apart the cluster assembly) and move the light bulb from one spot to another. Did you do this?

I found this image on the forum a while back and saved it...

Yes I did. The lights powers up when the car is started as the gauges are cycling the self check. Then it turns off when I start the car. But I did do the airbag light relocation. Thanks for the heads up Stealthy4. Cheers
