Hello,

It looks like the SAM module is out. To be sure lets clear the codes and then turn the key on without starting the engine to see which codes come up. Here are two guides to help us:

Please run down these guides and report back.

Okay, it looks like the CAN is not working due to the failure of the airbag control module. To be sure here are the airbag wiring diagrams so you can test for power and grounds with the airbag module replacement instructions:

Check out the diagrams (below). Please let us know what you find.
