I sprayed the heck out of it with QD Electronics cleaner and added some dielectric grease, but its still throwing the flashing "32" code. I guess I need to really get in there with something to scrape at the metal get through corrosion? What kind of tool could I use for that?

 

Have you also checked the plug under the seat thst the pretensioner plugs into?

 

That's the plug I'm talking about.
