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...
Phil D Posted January 17, 2016 Report Share Posted January 17, 2016 Thanks, Heavyduty. I haven't had that problem, but it's something to keep in mind if a strange SM code shows up. Link to comment Share on other sites More sharing options...

Brad & Jacolyn Posted January 18, 2016 Report Share Posted January 18, 2016 Where is that switch and how is it adjusted? I had to have an adjustment of the brake pedal once because it would bounce and disengage the cruise and it would also set off an alarm. I don't remember a code. Until I had Chance adjust it I used a baby bungy to hold the pedal up higher and solved the problem until I could get an adjustment. Brad Link to comment Share on other sites More sharing options...
heavyduty Posted January 18, 2016 Author Report Share Posted January 18, 2016 Brad pull the panel off on the lower right side of the steering column. Two torx 25 at top and on 10mm at bottom by floor mat. Look up under your break light switch looks like a spring comming out of it that touches the break peddle when it is applied. More than likely it is adjusted up to far and is activating when you hit a bump and kick your cruse off. What mine was doing is the same but it would avtivate while I was accelerating and the computer was confused and set off a sm code and a audible alarm. To fix it all you have to do is loosen a 12mm bolt above the switch and pivot the bracket back so the spring is not in contact with the brake pedal at all times. Be carfull not to adjust it back to far or your break lights will be slow to come on or your cruse will not deactivate. I was all over and under my truck pulled ever connection apart and cleaned everything and was no help. Then after about the 10th test drive I noticed that after the code went off it would stay on until I came to a stop sign and applied the break and then it would clear itself. Then the light came on in my old brain went back to the shop took 5 minutes to adjust and fixed the problem. After several weeks off every spare moment I had and several cases of Dr Pepper. Hope this helps. Link to comment Share on other sites More sharing options...
