Cobalt BCM Coding

I replace a Body Control Module in a 2006 Chevy Cobalt with a replacement unit from a salvage yard. Using the MaxiSys MS906TS I will show you how to code the Body control module to the PCM and how to Code the Radio to the BCM.

This was an awesome help. Even a trained 20 year veteran couldnt explain how to match a new BCM for a pontiac G6 from this era. This video helped us get it done with the bonus of unlocking the stereo. You rock!!! Hope you make more videos for us coding and programing newbies. Definately subscribing. Thanks.

Installed a salvaged bcm on a 2006 Chevy Malibu Maxx SS the exact same way. and it worked. I just used the exact same part number of the Bcm. used the Rpo code for the radio and worked fine. No issues

I have a 2006 Solstice Manual Basic 2.4L

Discovered this past winter that a few inches of ice/water on floor of my downward tilting solstice from rear window leak caused BCM failure. Removed fuses/relays & battery cable. Exact part# replacement BCM from same model/year proved a positive step, except for the mileage off by 10k, the LOCKED displayed on the radio which I was going to replace anyway, and the engine won't crank.

I have done the 10-12m sequences to relearn my keys several times without success. Best doc I found is: key position to crank then release, leave 12m then off 10s, repeat twice more, remove key 1m, then it sould start. I have a P0315 Crankshaft Position System Variation Not Learned that I clear but immediately returns. No other codes but engine light remains on.

During the key relearn the security light will not go out. During initial attempts to crank, I do hear the fuel pump charge the fuel line. Security light stays solid.

When the ignition key put into the RUN position, at the main fuse panel in the engine compartment, both the RUN Crank [51] relay pulls in and the crank fuse [5] terminals are hot . Battery fully charged as I have had this car on a battery charger for weeks.

The tech on Just Ask said:
The BCM will need to be programmed with a GM Tech2 scan tool and access to GM tech site to download software.There is not a workaround for this. You will need to call around to your local GM dealers to find one to do the programming as many refuse to do the programming for customer installed control modules.

Can this scan program tool fix this ?

And just when I thought I had ECM tuning down, I'm starting to discover a whole new world of pain and suffering these manufactures continue to perpetrate on my wallet. My Cobalt is having the "auto door lock" issue where they just do their own thing all the time, in addition to that, now the trunk doesn't open.

I'm stuck overseas now, otherwise I would see what codes come up on my laptop, but HPTuners only really has access to the PCM/ECM, not the BCM. So really, if it is the BCM it's not something I can program or override or switch off certain features like I do on ECM's for modded cars for other needless sensors (like egr or downstream O2's on catless setups). HpTuners can relink VATS, and do crank relearns though, which makes ECM swaps (07 and older at least) a breeze. When I get back in a few weeks and start to fix this thing I'll report back since I don't usually get much newer than 2002 as far as swapping goes lol. Tuning is a whole other thing in of itself, but requires no special linking or programming of modules per-se. Just modifying the tune, then a quick flash.

Looks like I have to open up my wallet again if I want to stay independent. But seriously, if one of these units goes for 2k+, then why not just pick up a Tech 2?

Great video thanks for your hard work.

Remember when cars were simple to repair, and didn’t require fancy pansy scan tools, for repairs, programming electronic parts to “talk” to the engine computer before the car can start, and paying a fortune to cut an extra ignition key, and another to reprogram fobs????
Yea, I certainly do!!!!
I’m glad I still have an old truck. No one can steer me off of a cliff remotely from a laptop on the other side of this rock.

This guy in the video didn't reprogram de bcm.you need to log into acdelcodts to get all the reprogramming files for that bcm.

Hi! How to reprogram a bcm to remove code u1000 u3000? (Ranger 2016, headlights issue). Ford wants me to change the module but I’ve seen it can just be reprogrammed.. no one does it where I live. Thought of learning to do it. Thank you in advance.

I have the MS906bt and would like to code in a new AC/ Heater control on 2009 Enclave. There are no options that I can find that will allow me to do that. Nothing under HVAC or BCM and going to special functions in each area. Any ideas?

[josetrevino]

I changed the BCM, and I had placed a pin code of a Nissan Altima 3.5, 2008 and it blocked everything, What went wrong, thanks, for you help.

[richardmiller]

Great video, but in checking my MAXySYS mini I do not have the option for programming the BCM for my 2002 Silverado.

[MrJohnnyDistortion]

In an '07 Cobalt does the BCM have any influence over the blower fan switch. Switch was replaced with no results, also replaced the head unit twice, no dice. Good power to all connections and blower spins when hotwired. Any clues?

[JamesWorley]

What about programming the vehicles VIN number into the BCM ?

[TheWillingCoyote]

Am I missing something? Your video comment says that you replaced a Cobalt BCM from a junkyard and that the video will show how to code the BCM to the PCM. The Cobalt and the Solstice actually have a lot in common. I bought an identical used BCM on ebay. I need to do the same thing you did ... right?... or are there procedures that these units cannot do that are prerequisites? Thanks in advance and for posting.

[tonysteeves]

We install a used BCM into our cobalt ss . We took the car to the dealer to reprogram it and unlock the radio and they said couldn’t communicate with it. Took $70 dollars even though they did nothing. It appears in your video it is possible reprogram a salvaged bcm?

[mperlatti]

Do you have to reprogram already established keyfobs?

[kagisodeboyce]

If you try to program the BCM actually the second hand one and find out that the software is protected what is the other option?

[darcymcintosh]

I found a used one and the PN and Delphi numbers are exact just the * (1T) at the bottom is 2 digits different, does that matter? TIA

[rohanboswell]

So the problem I'm having is I don't know how to tell what type of HVAC system or radio or a lot of question it ask while I'm connecting my autel ms908spro,

What kinda program thing r u useing on ur handheld tablet thing I would like to have ur set up please let me know I have a 2010 colbalt and it need computer
