The dealer might be able to tell you who flashed the BCM. There is also a small chance that there is a warranty.

Emphasis on might and small.

JohnWR,

Thank you so much for helping to determine why my door locks are not working. It surely sounds like a software issue. I will get that looked at when I get the brake pedal sensor calibrated.

I am seeing the light at the end of the tunnel. Once the door locks and brake pedal sensor calibration are done (hoping the calibration wakes up the cruise control) the rest for me is straight forward with installing the balance of the interior, some brake work, more polishing, a little touch-up paint, and paintless dent removal.

I finally got a chance to look up cruise control troubleshooting. Under Cruise Control Inoperative/Malfunctioning is this Diagnostic Aid: "Inspect for proper operation of the stop lamps." So there is a pretty good chance that the BPP sensor is the problem there.

Thanks for the technical encouragement. I have to call my friend at Link Automotive in Rolling Meadows, IL. I would much rather he help me, if he has the capability. With the good weather here, I've been heavily distracted catching up on desperately needed yard work. :(

JohnWR,

I am emailing my mechanic friend. I am mentioning that option codes AU0 and AU3 are likely needing to be programmed into the BCM. Are there others to include to get the alarm system and power door locks operational? I also wonder if menu item #7 AUTO UNLOCK will automatically show up in my DIC.

I wonder if option codes can be added, or if all the codes are cleared and you start over from scratch.

My friend who owns Link Automotive in Rolling Meadows, IL says he can take care of the programming of the BCM and calibration of the brake pedal sensor for me. I will bring all my FOBs in case he needs to reprogram them. I have to assemble enough of the car so water won't get inside. But I still want the interior stripped in case he wants to check something behind panels. I also want to wait for the rain here to stop being a threat. We've had serious flooding in the area. I have to drop the car off, not wait for it, so I don't know how long it will sit outside in his parking lot.

That's good news. The RCDLR should not be affected, but sending the fobs along is certainly a good precaution.

I've had my Sky at my friend's auto repair shop for 3 weeks now. He finally got past his rush of work since COVID-19 lifted around here.

He called and asked me if the BCM was replaced. I told him I assumed so because my odometer states 9500 miles when it should state around 120,000 miles. He told me that using his equipment (I assume the Tech-II talked about here so much) he was able to get into the BCM software but was not successful in getting the brake light calibrated, nor getting the power door locks to work. He reloaded the software from scratch and got the same negative results. He was able to work the power door locks through his equipment so he feels the trouble is with the BCM. He said the BCM installed in the car has the correct part number though he cannot tell if it is the original one. He has a remanufactured BCM on-order from a personal source and will try that one. If it doesn't solve the problem, he says he should be able to return it.

With a remanufactured BCM, I requested to increase the odometer reading to reflect the actual mileage of 120,000 miles. He responded saying he did not see a menu option for the odometer, but he will keep that in-mind. He thought the odometer reading was stored inside the instrument cluster. I told him the Sky forum says it is stored in the BCM.

I will continue to post what happens next.

If he can operate the door locks with the Tech2, the problem is not physically in the BCM.

I am curious about how he "reloaded the software".

I got a call today. My Sky is all good now with the brake lights, cruise control, and power door locks working properly. Unfortunately I couldn't get to the shop before they closed so the car sits in the shop waiting for me Monday.

My friend suspected the BCM in the car was not the original one, and it was installed without proper programming. The (new replacement) remanufactured BCM gave him all the right prompts including the opportunity to input the odometer reading. Given all the information I have gathered from the car itself along with it's Carfax history, I estimated the actual miles to be 120,000, not 9,500 so I instructed him to input 120,000 miles.

He did not mention anything with regards to the adding of TPMS, and I forgot to ask him about it. I assume he was not able to add that 2008 feature into my 2007 Sky. He did tell me earlier that such features are VIN specific.

Cost to me is going to be just under $800. Money Pit jabs me one more time. For the money alone that I put into it, I could have bought a nice low mileage Red Line. My countless hours in the car can't be tabulated to a dollar value. We better get a lot of joy out of this thing when it's done.

Glad you are slowly getting your car back into shape. I just took the cover off mine tonight, giving it a good clean up tomorrow and hopefully be ready for a few months of top down driving.

Ha, I went for the "nice low mileage Redline" thinking the same... 6k later...

Our 2007 Sky is back home with everything working properly, so I now have brake lights, cruise control, and power door locks. I wasted so many hours on all that. If only I knew then what I know today. The problem was 100% related to the old BCM and/or the programming to it when it was installed. My friend said that he suspects it was not the original BCM. He was unable to reprogram that BCM, but the new (remanufactured) unit was wide open for him to program everything the car was equipped with as well as setting the odometer to reflect the actual miles on the car. He also mentioned setting the ABS so I might not have had working ABS until now. He was not able to cheat the system to add the 2008 model year TPMS feature, but no great loss. I am happy I have 100% of the car finally functioning as designed.

So now I can move forward with the balance of this mild restoration project.

I'm glad that you got this sorted out. The TPMS would have been nice, but it was a long shot.

I assume the data had to be downloaded from GM. Is this correct? Some more detail about the reprogramming would be really helpful for the next 2007 owner that has to replace a BCM.

JohnWR,

I just got off the phone with my friend.

He told me his Tech-II equipment has all BCM related data permanently stored inside it to program the BCM.

Because of my multiple issues, he went an extra step and updated the software in the ECM and IP. That cost me extra because it cost him extra to download it. He said the annual GM subscription for that is crazy expensive so he pays as needed. He did not know if the ECM/IP update did any good. He wanted to make sure there were no hidden gremlins so he did that update only as "precautionary insurance" the car would be perfect for me.

I agree, the TPMS would have been nice. But it's good to have my Sky working right, even without TPMS.

I have been busy on my Honey-Do list, now trying to squeeze in a little time here and there to get the balance of the car complete since it is back home in our garage.

TPMS is not worth worrying about. Mine has never worked and I dont miss it. Its just another bell to maintain that doesnt work when it does work.

Thanks for checking on that.

The lazy in me missed the TPMS when I switched cars this morning, but I have survived this long.
