If the brake lights ( in the rear of the car) are on but your foot is not on the brake pedal, most likely the BCM 'thinks' the pedal is depressed when it isn't. The brake pedal position sensor is not a simple on/off switch like the good old days. The sensor is also most likely not the problem. Fretting corrosion on the BCM connectors will change the voltage the BCM 'sees' from the BPPS and will change the actual counts as seen on a scan tool in BCM data. The fix is to work the BCM connectors a few times to clean off the fretting corrosion and the problem will go away for a while. You can do that yourself easily by disconnecting the battery with the key off and disconnecting the BCM connectors with the blue lock lever and disconnect and reconnect the conectors a few times. Don't side load the connectors. You could also use a product like deoxit but you would need the cleaner 'D series' and the protector 'gold series' to make a lasting repair. Then the BPPS learn should be done to zero the sensor and your lights should work properly again.
Welcome back Rodents.
It's been my experience that the fretting corrosion at the BCM issue doesn't set any DTCs in the Gen 7.
nothing against you guys... youve allways helped me out i just thought it was messed up that one dealer says one thing and the other gives me a print out of 11 codes granted i paided for the 11 codes but the dealer that told me one code i bought the car from them... just saying doesnt seem right but so far so good lights are off in the car and my wife is off my ass so its all good!!

Good to be back. Thanks.
I'll be here from time to time but not an every day thing for quite some time, maybe I can add something useful from time to time.
I'll beg to differ with your statement pertaining to DTC's and fretting corrosion on gen7. Check out SI doc 2535089 or bulletin 08-05-22-009C, whichever way you can access it. That bulletin should be updated to include later model years but I guess it's too much trouble. They don't address a lot of things in SI anymore, I gave up sending feedback as the answerback usually included the fact that I was right and numerous requests to change SI were made and ignored.

My bad. You're absolutely right. The OP even gave the text of a c0277 06 code, I was just too lazy to look it up. I really need a vacation where the sun is shining.

Your expectations are too high. You want a vacation AND the sun to shine at your vacaton destination. Maybe your luck is better than mine. I'd be happy with just one of those, my heart would skip a beat or three to get a sunny vacation. Doesn't hurt to dream though.
We were thinking about a Caribbean cruise before the hurricane season arrives. Last time we went to Hawaii, it rained 9 out of 10 days (which I thought was statistically impossible there).
