CoupeDTS Posted November 24, 2007 Report Share Posted November 24, 2007 Past two years when it gets cold round this time of year my "security" light comes on. I get these same two codes B1009 B2734. Nearly everytime i get in the car too. Now its even saying "service theft system" sometimes. I know what the code lists say but it dont make sense to me as to whats wrong or how to fix it. Ive searched the forumn too. Whats goin on?
