Not sure if it has anything to do with it, but the truck is Canadian built fwiw.

Thanks Mike - sorry, I thought you meant in your first post that you found a 500 code on your truck somewhere, SPID, fwall, etc. Caught your SPID later in the other thread aslo - makes more sense now - you should not see 500 on a 73 light duty SPID.
