Got the dreaded srs red light and tracked down a loose wire on the drivers seat buckle and soldered it up. Whilst faffing with all the connections I removed the green push connector which attaches to the belt tensioner .....just to check it out and be being inquisitive and all - all seemed well underneath. Put the whole thing back together feeling very pleased with myself only to get this 9182 code. After hours of scouring for reasons I took the seat out again and noticed I had pushed the green connector thingy in after pushing the retaining pin in. as a consequence it was not contacting at all. Pushed it in, then the retaining pin and hey presto after clearing the fault all is well. Moral of the story is always put back properly what you take out and you can be too inquisitive!
