heavyduty Posted January 17, 2016 Report Share Posted January 17, 2016 Just FYI been chasing a problem with a SM code and audible alarm for 2 months. Finally chased it to brake light switch out of adjustment. Who would have thought. When I hit a bump the brake lights would activate while I was accelerating causing the problem. Lots of hours checking everything and scratching my head for such a simple fix. Link to comment Share on other sites More sharing options...
