Strange you’re not getting an air bag light my assumption would be nothing is wrong if that light is not appearing and fuse 3 is good but I’m not sure? I’m dealing with the a similar issue issue and purchased a junk yard module and didn’t realize it’s not plug and play (apparently another member posted theirs worked like that) but if you get anywhere let me know. I’m waiting on a carsoft MB scanner to test my air bag faults.
