air bag module

About 6 months ago my airbag light started flashing a code 52 which is a non-functional air bag module. I was able to get a good module from a salvage yard that had the same serial and part numbers. After the installation the light went out and all was normal until this past weekend. The truck had been sitting a while so I guess the battery was a little weak. When I went to start it the truck cranked slowly but it did start. After it started the airbag light started flashing a code 12 which is low voltage. The battery is charged now but the light is still flashing. Do I need to change the module again or will the light eventually go out?

Once again my air bag module is showing a code 52 (bad module). This is the second time this has happened after a major rainstorm. Obviously my moonroof is leaking but I cant see from where. Does anyone have any ideas?

Check the sunroof drains in the corners of the pan when the sunroof is open. If those are clogged, water will usually find it's way into the cabin, most likely running down the A-pillar. Pour water down the drains, and if water backs up, that's your culprit.
