Loose should not result in a fault.
There are two Torx screws that attach the bag assy to the wheel. IIRC they are T25's
To tighten -
Turn the steering wheel 90 degrees left from straight ahead position.
Reach behind the wheel with the T25 driver, find the recess where the screw lives and snug it down.
Turn the wheel back to center, then 90 degrees right from the straight ahead position.
Find and tighten the second screw.
All better!
