Any ideas as to why the autolamp/security lamp on an 05 Lariat Supercrew would come on steady when driving? Could it be something to due with the PATS system? Would checking codes with the Xcal 2 tell anything?

 

mine did that once for a short trip, ill be watching this thread

 

Mine did that one time also. I picked up my son on the way home from work and the light was not on before I picked him up. We left his school and I noticed a few blocks later that the light was on. I stopped at a red and turned the truck off and back on and the light was off. I have been wondering what caused it to happen, but never asked. That was about 2 or 3 months ago and it hasn't happened since.
