- This video will show you how to replace the Body Control Module in a 2003-2006 (possibly other years)Tahoe, Suburban, Avalanche, Silverado, Sierra, Escalade including how to relearn the security feature so that your vehicle will start with the replacement BCM installed. This truck has the 5.3 vortec v8 engine
Just to clear up some confusion this will not work for anyone who buys a new BCM from Amazon or elsewhere like I did. The process in this video only works on a BCM that is already programmed to the specifications of your vehicle. Hence the importance of the matched part numbers. If you buy a new BCM the part number will not match and it will not have any programming whatsoever. This will require you to bring your vehicle to the dealer for programming or to someone with the proper equipment and knowledge to do so. I purchased a new BCM and plan to discuss options with the local GM dealer about the BCM programming. Either I drive my vehicle down there with the bad BCM installed, hand them the new one and have them install and program it, or install the new BCM myself and have my vehicle towed to them for programming. I have a hunch I won't save much money either way.
Thanks for clearing this up. I have pinned your comment to the top so hopefully it will be seen. I realized I stated that all the numbers matched up on mine in the video but failed to get into the importance of them matching.
Hey dave I've got a really dumb question for you I really hope you are able to answer! I've got an 03 Escalade esv and I started having a/c and other issues and thought it was the bcm that was the culprit! Sooo, I bought a bcm from a diner escalade and found the relearn secret hand shake to get it to start and work properly! Heres where the issue starts. So, the truck does everything it's supposed to but has the same problems as before, so it wasnt my original bcm that was the problem! All was good except that the truck through a permanent code for the airbag! I know once alot of vehicles hit 100k they automatically drip a code for the air bags so you will take it to the dealer to get a check up done on your system. My original bcm didnt throw this code. For safety sake, (months later) today I finally got around to changing my original bcm back into the escalade. I went to go do the secret hand shake process (4x 10 min, cycle key, bla bla bla) well to my surprise the truck actually started right away with no hesitation! It didnt do the turn over start and shut right off routine! Everything worked as it should except the little lockout idiot light on the dash was solid lit up would go out, and wouldnt flash so I could do the re-learn process! I went to clear my check engine light and see what/if my code scanner had to say. The scanner wouldnt even pick up that it was connected to the truck? The a/c & heat worker recently accept it cut in and out a bit? But the windows auto door locks, door remote fob everything works? Any thoughts on getting the dash lock light to flash so I can get the bcm to relearn the truck again. Again I've now got the original bcm the truck originally had in it. I'm guessing it restarted right away because the bcm originally came in the truck but if that's the case I cant figure for the life of me how to all the way get the original bcm all the remated again and have no airbag dash light so it's safe for the family to cruise in again.. thanks, hopefully you see this soon and are able to give helpful input because I'm sitting in the drivers seat now with the hood up... 30 jan 2020 4pm

So where did you get your replacement BCM?
I ordered a BCM off flagship one for $200 gave them my vin and they flashed it , then this relearn worked for my 2003 tahoe with no other messages. So thanks man

This is best video on this BCM repair I have seen. EXCELLENT JOB!
Rich Barnes thanks for the comment. Hope you were able to get yours fixed
Agreed
man thank you so much you help so much im so happy i got my truck turn back on again thank you so much you have to still making videos like this helps a lot god bless you
David Gonzalez glad your truck is fixed
Easy peasy! Dash came apart without a fight. Connections were easily removed. Old BCM came out quickly and after putting it in backwards, the new BCM went in the slot. Connections were quick. Going through the off/on cycles to program the new BCM took time, but went exactly as instructed. Truck started and idle came back down within a few minutes. No issues. On mine, the seat belt alarm went off continuously and the head lights only worked when manually turned on. This corrected both issues. Rebuild BCM at O'Reileys was just over $300. Thanks for the video!
Thanks. Glad it fixed the issues
If the bcm is going out would it stop you from reading the service engine code? Or the code reader from powering up/ acknowledging the vehicle?
A blown fuse for ur cigarette lighter can cause it not to power up a code reader. Have no idea why but it worked on 05 Silverado
What drove you to replace the BCM? I have a 2006 GMC sierra 1500 Quad cab 5.3 z71 and I will be driving and all the digital displays will go out. Radio, climate controls, mileage trip odometer. Will replacing this fix my issue?
Im here because my 05 Sierras dash, windowy, radio, locks, and ac just 💩the bed. Thanks for your time and knowledge. My truck only has 86k miles and runs great.
Did u find out the problem? Having same issue
Great video! So, my friend said that if I live in California I should definitely buy one programmed to my VIN number instead of buying one that fits my exact car off eBay because apparently I would then have to go have it programmed or otherwise it wouldn't pass smog in california?
Very effective just brought back my Tahoe from the mechanic cause he couldn’t program it & look I saved my self some money
Yeah I had a coworker tell me he paid like $180 to get his programmed. I told him he could have saved a lot of money by hitting the subscribe button and watching my videos. I am glad you were able to get it fixed.
Hello. I have a 2004 suburban. And I keep getting these issues, no crank/half crank it will eventually start, ABS and Parking brake light, TPMS, Service 4wd,and Service Brake System. Are these issues that can be cause by the BCM? Just trying to get some answers.
I've replaced the ignition switch, checked the pcm for corrosion on the connectors, brand new starter, checked fuses, checked ABS and engine grounds.
Here is a link to a video that might help you. This is not my video bit may solve your problem th-cam.com/video/XSApoE5tUtQ/w-d-xo.html
Did you replace ur bcm to fix these issues? Did it work? Im having similiar w my 04 avalanche although it starts everytime...but serv messages park brake and i have 0 as odometer but truck had 190k+ avg and instant mpg not working either, speedo does
My 03 Silverado single cab drains my battery... it keeps passing power to my power windows even after turning off the truck and taking the key out... do you think the bcm would be the problem??? I have to disconnect the negative cable if not itll drain the power out
I am not sure what would fix that. It may be easier to pull the window fuse rather than the battery cable, but that still doesn't fix the problem. Best of luck to you though
I’m trying to program my BCM, it’s not working. I’ve tried several times and by looking at your video I see that my security light stays on and does not flash. Do you think that is the problem?
What are the symptoms of bad Bcm?
Anyone purchase a dorman BCM from RockAuto ? and will that work?
Great vid. I also ordered an eBay bcm and had my Vin programmed. However upon completing that relearn process I now have a “service airbag” displayed on my cluster. Error code B1001. Now I have to either go to the dealer or find a mechanic that can utilize a scan tool to make the airbag module (SDM) communicate with the new BCM. The headache continues.
Did you ever find out the air bag issue? I did the same and mine has the damn airbag light on 😭
If I get one with the same #’s will I have to do anything to program the mileage or. Is that not affected with the BCM?
Thank you for the help but the heater thing on my truck slides off from the right side it doesn’t pull off like yours did I felt stupid
Hopefully the rest of the replacement went smoothly for you
My ac turns on and off I changed everything would it be this module a possibility
He is telling the truth. This works. No scanner.
where did you bough the replacement , was preprogramm it or new or from a junk yard? need to know I have problems whit mine is a 2003 silverado
maricarmen flores I purchased mine used from eBay. Would be the same as getting it from the junk yard. It needs to have the same part number as your original BCM and should work after the relearn process. It is my understanding that it will need to be reprogrammed by dealer for the factory stereo to work. I have an aftermarket stereo installed and did not need to reprogram. Hope this answers your question
You done good, fella’! Searched for over a week.
Well done, You blew everybody else away that I've seen do this. Clear and concise.
Born Again Torinos thanks. Hope it helped you out. As soon as I get a chance I plan on doing the MAF sensor
I'm a little concerned that the factory stereo might not work after changing the BCM. I have a 2003 Yukon. Today it has started saying the rear hatch is open when it is closed. The interior lights are staying on so I pushed the override so they wouldn't drain the battery.
I'm not sure on that one. That is something I read on a Tahoe forum but since I was dealing with a aftermarket stereo I didn't have to worry about it. You may be able to get that info from a dealership or mechanic weather or not it will need reprogrammed
Hey dave does the bcm control the remote door locks?
Anyone know anywhere that will program a bcm for a 2001 Saturn l300? I've called just about everyone and no luck, im trying to use a used one from the junkyard because I can't find a new one anywhere because obviously Saturn has been discontinued. Thanks for any information.
I Replace my BCM, on my Chevrolet Colorado 2006, put the key at ON 10 minute but the Security Light never turn off, ANY Recomendation?
I have a 2001 GMC Sierra. Replaced my BCM with same part # . Procedure worked. I now have a security warning lamp every time door is opened and air bag warning lamp is on but no dtc scanned. What have others done to resolve this?
So, you telling me I could put a new BCM in my 2008; Chevy Express Van, and perform that key relearn and it will start right up.?
How about pick n pull for a used one? Or a non dealer source? 2001 chevy Silverado. Amp test immediately identified BCM circuit. Pull that fuse and no more draw. Now for the fix…
Perfect way to explain it thanks
Glad to here it. Thanks
Why do all you guys get bolt and screw size wrong. You are actually telling people the socket size. If you tell someone you remove a 10 mm bolt and they loose the bolt. When they go to hardware or AutoZone and buy a 10mm bolt , they will find it is 6 times larger then what they have.
So I replaced the bcm and the truck fired up and runs fine without the relearning sequence. I still have no power to locks, windows, ac, or dash cluster.
Would have helped if you explained why you are changing the bcm. Gm makes junk with cheap chinese parts which often fail
Any idea if this will work for a 2000 Silverado?
Ceasar Luna it should be the same procedure. I am not sure if it is located in the same spot. Make sure the replacement bcm has the same part number
Hey, I have an issue in my 04 1500 Suburban; when Im driving and pass for a irregular ways ( Cause I live i Mexico) the locks use to unlock, sometimes the ABS sign on the panel lights on, sometimes the engine turns off! Could be a problem of the BCM?
Tnx
I ordered a bcm from amazon and did the relearn process but my truck started the first time and now one of my charging ports doesn't work my obd port doesn't work my airbag and security lights stay on🤔
I got a used BMC from a 2004 Tahoe for my 2005 Tahoe Different numbers would that be a problem
I am pretty sure the part number needs to match up but you can always try it
@@daveaffolter9697 okay: thanks for the advice it's appreciated I will give it a try👍
Hi Dave big question for you Sir. I have a 03 yukon denali and my battery keep dieing, some say its the cluster not shutting down while parked at night also my radio is pulling power(fuse) too also amp(fuse) my question is can a bad BCM cause these units not to shut down when they suppose to my battery is dead like the next day but when charge everything works like they should.
There are many things that could cause your battery to drain. Also the battery could be bad. I believe the radio and a few other things draw some current for a few minutes after turning off the car(not positive on this). With mine the bcm caused the battery to die because the vehicle would randomly think the door was not shut and the dome lights would come on. Plus if it was locked that would cause the alarm to go off. Sorry I can't give you a definitive answer but good luck with it. I do know that I have had electrical problems with all four of my vehicles that had the vortec engine.
Did you ever get this fixed? I have the same issue on a 05 Yukon
I'm having the same problem any solution?
My battery was dying I used an infrared camera in the middle of winter to see what circuit was draining it. Came back to a 3way USB charger I had plugged into the lighter socket. I ruined 4 AGM batteries because of that bad accessory.
I had the right rear door ajar always on and my brights wouldn't work and my fog lights wouldn't turn on. I followed this to the tee on my 2003 Chevy avalanche and now my brights work again....the fog lights work again....and no more door ajar so now my inside lights won't always stay on thinking the door is open. Thank you for posting this was awesome. FYI I do have the factory Radio it now has a permanent red light on all the time but it doesn't work now so that part is true. I'm putting a Double Din in soon so I'm not worried about that.
So if I get a bcm from a Silverado that has steering wheel controls and put it in my Silverado that doesn’t have those control will it work and will I have a those controls?
I'm Lil confuse so
turn key 🔑 on 10sec til secure light is off do it 4 times
than wait 10 minutes
repeat all that 3 times?
Any idea if this works on 2003 Chevy trailblazer
Not sure if process is the same for that model. You could try checking out on of the trailblazer forums and see if anyone can help you out. Most of the people on those forums will happily answer your questions if they can
thanks for the uninstall portion of the video. I took my BCM out yesterday and the pins on the black tab had corrosion most likely caused by the leaking windshield (windshield now replaced). I cleaned the BCM board and all connectors, added dialectic grease the the plugs and no more dead battery this morning
That's awesome. Sometimes things work out
Was your dead battery the only symptom?....I troubleshot my draining battery to the BCM, but have no other issues caused by it.... like those other folks above. I dont want to get a new one only to get into more headaches like airbag lights etc if maybe I can just take it out, clean it, look for any bad solder joints, and put in some dielectric grease like you did.
@@stevehellwich463 Yes, my only issue was the parasitic draw causing the battery to go dead. Once I cleaned up the corrosion and applied the dialectic grease, I was good to go. Well worth the effort to get in there and get it done.
I had brought my 03 silverado in to get a transmission done, lost 3 and 4, new ones in now and the thing shifts better in 1 and 2 but still won't grab gear 3 and 4 and my tail lights act very wonky only 1 lights up at night, any ideas? Gonna try to clear codes see if it shifts fine, new shift cable as well
My 03 Silverado 4.3 will be driving then start dinging which causes the Brake and ABS lights to come on and flash
@The Man Delorean Nope the truck is 100% other wise only, does it maybe once every couple weeks for maybe 30 seconds
I tried to replace BCM in my 2006 Suburban with a used BCM numbers matched. When I try to do this procedure my security light stays solid. It never flashes so I was unable to get this to work. I did go through the motions and turned they on and off 4 times waiting 10 minutes in between but I ended up putting my original BCM back in. My mechanic says he has a guy that will reprogram it for $250 but I'm thinking to buy a scanner that is capable of reprogramming. Any feedback on this?
It's 3 times wait 5 seconds in between
Why is mine stuck is security lock now like it did it 3 times but towny did it the fourth it won’t blink it’s locked now?
I have a Cadillac CTS 2009 which I suspect will need a new BCM as all my radio Chaco and nav, everything in the centre cluster is dead.
Can you help with resetting sequence
So I don’t have to go to dealer as I’m n the UK
Sorry, I am not familiar with the 2009 CTS at all
Could bmc be reason why I have no power to trailer right turn signal
Thanks. I read somewhere that you need to clear the engine codes because the ECL will be triggered after swapping things out. Not sure of this though.
Okay so how would I clear the codes when the truck won’t turn on because my bcm isn’t programmed to it and the code reader can’t connect?
@@sinn100iq9 Might need a dealer 🤔
I love this video not a bunch of bullshit like most of the people here on TH-cam all they do is talk talk talk talk bullshit about stupid things that I love about this video get to the point get it over with and it’s done because peoples time is very valuable and other videos treat you like a stupid kid this one treat you like a man get it done boy that’s what I like about it.

Will it cure my problem with AC control and temp reading on rear view mirror? Changed temp sensor in behind grill and got different rear view.
thanks thanks
Can I do that to cadillac cts 2003 after I changed the BCM?
The process worked but my rear access is still on so I’m assuming the bcm was not the issue for me
I have rear asses open service ride control air bag servise astavility taction control brake abs light blinkings and come off while driving have to restard the truck for it to go aeay help!!
I am not sure what the problem could be.
Tks ifix my tahoe 2003
Glad to hear it.
I have a 03 GMC Sierra, that won’t turn off.. even after key extraction. Could bcm be the culprit?
I am not sure on That one. It may be related but could also be something else electrical. Maybe ignition switch
Would like to get a quote on a BCM for my chevy thoe.03
My 4 small gauges don’t work and the gear indicator, and the electric windows or locks and the obd won’t communicate, it powers up but won’t connect to the scan tool. I was told that it sounds like the bcm,
I shorted something out behind the radio but can’t find any blown fuses. Does this sound like it could be the bcm? Tia
Did you find out if it was your BCM. I have the exact same issue.
I'm wondering too I watched my gear selectors lights fade and my clock reset.
I have a 2004 tahoe that doe not want to start after I unlock the doors with the alarm remote, sometimes it doesn't want to start I wait a few minutes and it starts right back up again. Could this be a problem with my bcm? Thanks in advance.
I am not sure on that one
I have 2001 GMC Yukon n I replaced it and still won't start
Hello Dave. We have a slightly different scenario with our new BCM in our 2005 Tahoe. I have installed a pre-programmed replacement but our engine started right up on the first turn of the starter...not a bad thing by itself, but it did create the need to pull the fuel pump relay to keep the engine from starting. Even with the fuel pump off, and following the steps you discussed in this video, I can't get the security key lamp to blink and then turn off after any amount of time. I elected to just let it sit for more than 15 minuets to see if the light would turn off, but it did not. So we are left with a new BCM that apparently I can't learn in to the car. Any ideas what else I can do to get it to learn it in? Is there a way to trick the computer into thinking that I have initiated the passcode learn procedure that I can try?
I do not know what would cause that issue
Thanks for your instructions. This procedure is useful in the chevy Trailblazer 2005?
Cool so you saying that was a programs on the bcm I can buy one at junk yard and do exactly you did easy I have a 2001 Tahoe and after market radio my problem are speed monitor light stay off and my parking lights,license lights and third brake light don’t work should I be ok with your steps lmk ty
It is a relearn process between the key/ignition and the bcm. This may take care of your issues it also may not. Could also be shorts in the wires, badd connection, blown fuse, etc. I am not sure if the speedometer light is connected. These vehicles tend to develop many issues in the dash cluster. I have had many of these with different dash issues. Hope you get your truck fixed. Sorry I couldn't be more help
i bought a 04 silverado that had the driver side airbag deployed, do i need to replace this part like you did?
SO did you loose your original/accurate Odometer reading with the install of the used BCM? I watched another video of a Saturn and the used BCM had a reading of 200k miles while the original BCM had a reading of 140k.
Nope. Odometer reading still accurate. I am pretty sure the odometer on these is stored in the dash. I know if you replace the dash on these you have to get the odometer reprogrammed
I bought a used one but the numbers do not match what should I do everything else is the same
You could try it. It might need reprogrammed at the dealership. Could always try and if it doesn't work out the old one back in
What was the problem in the 1st place?
I have a 2003 Escalade ESV, I had the "rear access open" issue. After lots of playing with the rear latches & sensors I bought a used BCM from a Tahoe (same part#) and did this relearn procedure and it worked like a charm, started after the 3rd 10min cycle. Rear access issue is now gone, but now I have airbag and stability lights on -_- the struggle continues!
Good luck with it. I have had many electrical issues with this generation GM vehicles
Whats the best way to remove the connectors. Hesitant to pull on them.
squeeze the clips on the plugs top and bottom.
I order mine from advance auto parts for my h2 hummer do you think this process works on mine
Not sure.
Honestly I tried this many times and it never worked then when I gave up I left it on for like an hour and it cranked up and started working it was magical.v
Sorry you had the trouble, but glad to here it is working
Will this work with 2001 Chevy impala 3.4
I am not familiar with the Impala, sorry
Tienen q coincidir todos los numeros o nada mas los de arriba?
I replaced my bcm in my sierra 06 and did the procedure. It starts but my radio is still picking up interference and my air bag light is on all the time
I do not think that either of your problems are related to the BCM. The airbag light may be a fuse or possibly the front impact airbag sensor. The radio interference is strange. Could position be a bad ground.
VERY good video.
Thank you
You have to get it programed
what if your truck crank up on the 3rd time
Great video and very informative..! I have a 2007 ext Cadillac..any chance that you can tell me why my backup/reverse lights stay on? I replaced the brake switch on the brake pedal...someone said the relay to the backup/reverse lights burned out in the ON position but I cant find the rela ... someone else said that the relay to the backup/reverse lights is in that little BCM black box that your working on?
I have heard of people having to replace the fuse box to fix that problem. Was also told it could be the park neutral safety switch. The bcm also has something to do with the reverse light. For a temporary workaround you may be able to pull the fuse if nothing else is on that fuse
@@daveaffolter9697 Thank you so much for your input... much appreciated!
Would it work with a junkyard BCM?
It should as long as the numbers match up. This was basically a junk yard bcm. I got it of ebay used and was not programmed to my car. All I did was the steps in the video.

Hey I have a 2003 Tahoe as well. I ordered the BCM from Amazon but it wasn’t the same part number. I asked a dealer friend and they said some part numbers were changed years back but are the same as OEM. When I replaced my BCM the security light came on but didn’t stay on. Do you know why that could be?
I don't have a clue on that. You could try the relearn again
Did you get the BCM with the different part number to work?
Yes. I had to bring it to the dealership though so they could program it. $97 SMH
@@clarencespencer5143 Did you install the BCM and then tow your vehicle to the dealer for programming? Or did you drive your vehicle to the dealer and hand them the new BCM for installation and programming?
Thanks in advance!
Oh no I installed it myself using this video and then tried to program it myself using this video but it didn’t work so I had to get it towed.
What would cause your oil pressure to be slammed on Max like that? Cluster or the sensor?
I am not sure on that. I do know that cluster, along with all of that style I have owned (4 total) had cluster problems. GM really blew it on those clusters.
My personal experience tells me it's the sensor, easy I guess, disconnect the sensor to see if anything changes. If it's the cluster nothing will happen when you disconnect the sensor.
What stopped working to warrant a NEW BCM?
On this one the doors would randomly say the were ajar. This would make the alarm turn on (usually the middle of the night). Replacing the bcm fixed the issue
