Dude, you just described and touched on every single problem I am having with my 2008 Chevy HHR. Rear door hatch will not open (unless you put a fuse in an empty fuse position). My rear wiper on that door will not work although it does when you bypass the relay under the engine compartment fuse box. Rear left passenger door window will not roll up and down or is intermittent. ABS and Traction dash lights are on yet. There are no issues with those things. I just bought this a few days ago and I swear it feels like it is possessed. The funny thing? The car engine and transmission runs so damn well it rides smooth like a new car. I am a gigging musician who travels and needs the space in the back for some of my equipment. I thought these would be easy fixes. Speed sensors are working fine as they are relaying back perfect information and hooked up to a very expensive scanner can clear the lights but they just come on again. If I buy a new one or a used one, I hear they have to be programmed? Can only the dealer do this?
And edit to my comment, the dealer cannot fix or program these anymore, nor do they sell the body control module.
@@grumpyoldrockers1048 thats shitty, going thru same thing dash board lights come on but not the dome lights and i get a theft deterrent fault
Hi did u say after replacing BCM engine and transmission running smooth ?
Did yu change the battery to the keyfob ? Of yu did yu Probly drop the black pin with out that your car won’t work yu will have to get a locksmith to re program a new key
@@Manest3272 if you’re talking to me, yes I finally had my friend who works at with a Chevy dealer in Lake Havasu, Arizona (I live in California, but I play in Arizona all the time) put in a new body control module. Programmed everything perfect. The only thing that is not working is the traction control button probably need to have that programmed. But everything else is great now. I shouldn’t have to go to Arizona to have this done while California tells me they can no longer get these. What a crock of BS!
Very good explanation thank you for your time to teach God Bless 🙏🙏
VERY GOOD AND INFORMATIVE,THIS SOUNDS EXACTLY WHAT I NEED, WINDOW NOT WORKING, RADIO NOT WORKING, SIDE VIEW MIRRORS GOING CRAZY, HALF THE FIBERS OPTICS NOT ON OTHERS BLINKING ,
FOR AN HOURS WORK TO REPLACE IT AND $55.00 USED ONE WORTH THE SHUT
God damn bro calm down
Good overview on faulty bcm's and the consequences of interacting with the ecm and external inputs.
This could be daunting task for independent mechanics coming into a dealership, this information is spot on ...
I believe I fried the BCM on my '06 Taurus several years ago while doing an oil change. My filter wrench shorted out against the hot wire to the starter which Ford engineers decided did NOT need a rubber boot covering it. Always disconnect the battery cable or at the very least, wrap electrical tape around the band on the filter wrench on these vehicles.
My 07 suburban is doing this key on no crank, radio shuts off /on the dash shuts off /on windows heater controls sometimes it will start thank you for your video
thank you wonderful explanation on what the bcm and ecm do
Dude thank you so much I have those symptoms that my car have
I'm curious if this is my bmws issue. my carpet got flooded, and I started the car ever since doors won't lock .no ac lost all functions to windows .makes sense. I think I fried it prolly. Is it possible? Wen I started the car
Thanks for the informative video. I have an urgent request concerning a problem with my truck. This is an International truck. The DEF, check engine and the triangle lights came on. I was asked to change the Turbo Actuator. Two days later, same lights came back on. This time around, my mechanic said it's the Body Controller Module. He said there's no communication between the BCM and the Turbo Actuator. There is no loss of power from the truck. The truck runs good even when those lights came on both times. Is this really the problem? If this is the problem, can I use a used BCM or I should just go ahead and buy a brand new one? Thank you
2008 clio mk3----went to start yesterday-nothing just a clicking noise coming from BCM unit which is located under glove box--i then noticed wipers very slow and lights on dash flashing uncontrolably----tried numerous times same thing happened---rang mechanic-he said BCM unit needs removed and sent to specialist repair shop-----------cost about £350 sterling for fix --------not sure how much new one is i c one at £470 on ebay but then u have to take it to renault garage to get it reprogrammed-----would that cure my problem based on info i gave or would u recommend a new one-thanks for ur assistance
Thank you for the instructional video!
I brought a BCM its now at the FORD place costing me over 300 bucks but I hope it works ! Now they are calling me saying it might not be that ! After it was diagnosed elsewhere. They want more money from me. Smh
I have issues with the horn and the wipers on my Nissan Versa Hatchback 2008. I believe the BCM might be faulty. Everything else works fine.
does the bcm control ride quality c5 corvettes?. I get a service ride control message. Scanned vehicle but got no codes
2:43 Hello I have a 2003 Chevy avalanche 1500 4x4 z71 with 5.3 liter engine, some times or every other day on initial first startup and any start up through the day , I have reduce engine power, my cluster gauges flash , my language settings change from English to French or Spanish , my rear view mirror direction info start scrambling , I get engine sensor codes going off , and the sensor was replaced 2 todays before and engine stops running for about 20 miles rough down the road bad gas smell and then it shuts off , I have to wait for about a hr then it will start but rough and then it will smooth out very unpredictable . Also on initial morning startup it back fires loud and won’t start , then turn key off and starts right up fine and runs good for about 20 miles then dies . You think it’s bad bcm or ecm
my g35x wont start. i can press the push start & all the lights/accessories turn on but no crank or engine sound at all. the lights on the dash flicker as do the inside cabin lights & then it wont turn off by itself by push of the button. i have to disconnect the battery for the car to turn off again
Described every symptom my g37x had before limp mode was activated and tranny slipped! Thanks so much,infinitis are notorious for the damn sunroof leaks, i’m wondering if the BCM can be rebuilt so no reprogramming is necessary?
Confirms what I was told.
I have a 2011 Sonata LE that has a sunroof. Sometimes it work, but usually not. I see there are two fuses that service the Sunroof: a 7.5A fuse that also has BCM on it (column 5,mrow 2) as well as a 20a fuse on column 4, row 4). I think a short to the Sunroof switch or motor is draining my battery overnight, or two nights. If I pull the BCM Module 2 fuse, will it affect anything else? Thanks.
I have about 7 BCM codes but everything is working fine besides the remote start. Which is only not working assuming because of the codes. What else could it be if everything is functioning properly?
2019 f250
I’m working on a howo truck from china that fell into a ditch on its side , after making repairs we found the BCU badly damage , burnt to a crisp, I would like to know if the door lock or window switch can cause the BCU to fail if there are shorted out ?
I have a 06 DTS it will every once in a blue say service traction control and stabilitrak. I will show up and beep for a few seconds then stop then I may not see if for a while. It is giving a BCM module code but I feel like it may be a bad wire somewhere as it doesn't seem to affect anything else.
Do you think it would be the same problem for 2009 cadillac sts the trunk won't open and the airbag light came on. Also the power seats won't move forward or backwards. The steering wheel won't adjust either.
Dome Light not working, keeps blowing fuses. EVERYTHING else is working! What is the issue now? My BCM, as described seems to be ok.
I have a 2015 silverado 1500 LTZ. My dash lights sometimes flicker, headlights flicker and volt meter will bounce between 12 and 14.5 volts. I have checked both grounds in cab by A-pillars, both clean and no obstruction. Cleaned both grounds from battery to frame and motor and replaced battery ground sensor. I do get a loss of power steering but not that often. So could a failing BCM be responsible?
Since my last diagnosis, I have replaced ground clamp and had alternator checked. Voltage regulator failed test. Replaced alternator and system is now working correctly.
Thank you for posting the fix!!
🇺🇸💪🏻👊🏻🤙🏼
would this effect my remotes? I boughta new one as I thought my old one was wore out 2010 dodge Dakota. But the lock smith said they were working fine. It must me something in the car?
With access to the BCM, can I disable non-canbus recognition since I have LEDs all over the car?
My horn don't work sometimes. But my problem in my 05 Denali, the blower for front and back heat. One will blow one day maybe the other will work the next day. One usually works but mostly the front is out. New fan new resistor
Good video thanks,
my 2012 Volkswagen Sharan vehicle starts and drives without problem but the interior lighting, multimedia radio and sunroof no longer work. Do you have any idea of the problem? Thanks in advance.
First, start by checking for blown fuse or bad relays.
OK, I have watched your videos religiously. I replaced my BCM on my 08 HHR. Everything works great except the traction control button. It used to work before I replaced the BCM but after replacing, it no longer works. Is this something that can be controlled by the BCM? And can it still be programmed in there? In other words, did somebody not program it to work sorry for all the questions. Everything else came back to life except this one thing. And of course it’s bothering the hell out of me.
My father has a 05 grand cherokee, crank but no start and every time you turn the key the wipers cycle about a dozen times before finally stopp9ng in a random place, a bunch of codes for losimg connections , what do you think
My vehicle is ford ecosport 2015 modle. Ford has asked to bring my vehicle for recall(door locking programming system) and after that fog lamps not working. They tried everything by reprogramming with updates, fuse & relay replacement etc but still now they cannot identify the issue. What can be the problem could be?
So once I get the replacement BCM for my truck does it needs to be reprogrammed?
Yes
My brake light and high beam light on instrument cluster never fully turn off on mine. Suspecting a bad BCM. 04 Silverado
Ok I have a question, if i disconnect my BCM i have to disconnect the battery first? Then Remove the BCM and put things back in that order?
If i Remove BCM so i can get the part no. I will have to have it reprogrammed? Also After I remove it and put back the original one Will the car start with no issues? As I want to drive it back to the Programmer so he can program my ECU but i need to remove it to make sure I am getting the correct part. His Autel Scanner Read 284B2-89910 but I cannot for the life of me I can't find that part no. All the ones on Ebay or at online Dealers say 284B1-XXXXX but none says 284B2-89910 for the reason I must remove it to make sure what is the correct part no.
Thanks for your reply.
The drivers side passenger window has been randomly rolling down for about 7 years. My wipers sometimes stop while it's raining and then resume whenever they decide to
Also, since it communicates with other modules it can even create drivability issues with the car.
Wow this is everything that is wrong with my Kia Sportage 2011 - when I start up, for a few minutes the dashboard is fine but nothing works, then after a few minutes the blinking starts.......turn signals, lights, windows don't work. The guy who looked at it said that the BCM is faulty and I remember a few years back water was coming into the vehicle from top of the windshield that was not properly sealed.......seems it got into the BCM which is under the dash. Now I can't get a BCM because Kia no longer manufacture for the 2011 model. I have been searching every website I know of, but nothing.
What my tech can't tell me is if there is a way to modify the BCM since I can't get a replacement or does it mean my vehicle is now dead and done for since I can't drive at nights without lights.
Can a fCM cause my starter to not start ? Starter can jump from bolts but can't start from jumping from fuse , or from key . fCM was dented in fender bender
Could a faulty Bcm prevent the car from actually flipping over? I have a g37 2013
Hi. I changed engine in my Ford Kuga 2013. Which pcm should I use. The one on the previous engine or the one on the new engine’
Hi guys, I have a pb with my keys not detected when engine is one or off on my X5 f15. Do you know where can it’s be? Key battery, keys and bdc have been changed, but the pb still here. Any suggestion?
well explained Thank you (UK)
I'm having absolutely no issues with my car, BUT I lost a key and wanted a replacement from the dealership where I bought it. And they can't code the new key... Is there any possibility of it being the BCM? That's what they said last time (they've tried various things - it's been 8 visits - one year since I asked for a new spare key...)
I have all of this problem, , should i replace my BCM?
my unit is 2017 ford ecosport. The control module is insde the driver side door.
My problem with my Pontiac torrent is, the power stays on after I take the key out of the ignition. The windows roll up and down, the wipers turn on, the headlights turn on etc…, all without a key. Could this be a bcm problem?
Doed bcm supply low pulse the injectors and make the diesel car jerk? Specific to ford figo.
is it the BCM when i have things activate on their own. Horn stays on, Rear dome lights stay on, one rear window goes down on it's own, Rear winsheild wiper is sporadic, cd disc changer is always running. i have disconnect the battery when i park. its a 1999 Jeep Grand Cherokee
I had my bike (2016 Road Glide Special) off the tender for a while *2 weeks*. Bike started up fine moved the bike. Fired up bike again, VINERR code popped up. Bought a new a battery. No luck... All these codes all popped up-U0001,U0100, U0121, U0140, U0184. All the gauges all not working correctly. Thought bike would reset after a ride, nothing. Can you give me any answers to these issues?
Hello, if you have a bad bcm, could that cause all your sensors to throw a high & low voltage code, like P0118, P0122, P0223, & P0443. I change all the sensor connectors & sensors. Van still will not start. Have new spark plugs wires, spark plugs, & coils. No spark, even have new ECU. All fuses, & relays are good. New battery, alternator, starter, & water pump. Checked wire harness, & wires. They look like they're in good shape. I checked all my grounds, they were still connected well. What could be the reason for them codes still? My bcm is malfunctioning for sure. I noticed I had experienced some of those symptoms ya mentioned in the past. I was having ECU problems, but didn't realize I was having bcm problems, as well. Help.
Sell the car for parts
@@apppleboi2858 , No sir. Why would I do that and it's the engine harness, at fault. I'm repairing my engine harness, and replacing the ECU connectors. Ya know, when you do research and then proper diagnostics, it's easy to discover a proper solution to an electrical problem. Just ordered an aftermarket harness, to replace the bad wiring on my harness.
Kool video. Thanks for the information. Now I just want to be clear That is if I am having multiple symptoms, like the door, lights, dash flicking, wiper etc all at the same time? Not just one, correct?
It doesn’t need to all be at the same time and problems can be intermittent.
I have a 2017 Porsche Macan. I try to use the key fob to open my doors but they won’t open. I stick the fob into the fob slot and turn it to start the car I get nothing. I hear a clicking sound in the BCM box. Do you think the BCM is no good ?
Will the symptoms always be on/off problems. Could it cause issues such as things not working correctly rather than simply not working?
Yes problems most likely will be intermittent
Good afternoon.Pls can a faulty BCm make my infiniti ex35,2008 not to start and it had no key flashing on d dashboard whenever i press the start button
Need help; mazda cx5 with interior lights malfunction, headlamps dim, lock actuators malfunction and click constantly, trunk won’t open at times, car alarm won’t set occasionally, heat/ac does trippy stuff, radio acts up and now CEL with codes p013A, u0401:00 and u3003:16. I’m thinking it’s BCM but alternative solutions can be passenger side ground wire bolt has been painted during possible previous body work creating issue grounding (apparently a common issue with these vehicles) but ground wire could create some of my issues but doesn’t match everything. Wondering it 02 sensor code (p013A) is a separate issue or somehow connected to ground wire issue or even BCM faulty? Any suggestions?
I have a 2013 Ssangyong Stavic - Car has automatic locking at 50kmph. However the car will continue trying to lock the doors after they have already locked. And will then unlock as the car slows down. So car is constantly locking/unlocking the doors while driving. The aircon also works intermittently. Sometimes will be really cold, and other times feels like the heater is on with the same aircon setting. - I also have an electric window on the drivers side which is very slow to go back up. Could these all be symptoms of a faulty BCM?
Did you ever find out if the problem was your BCM? I'm having some of the same issues as you were,on my 2002 Dodge Stratus Sedan. My A/C blows cold then next min blows warm (I've already charged it & checked for leaks), My 2 back windows won't roll up or down, my horn honks intermittently and my dash lights flicker sometimes.
Hello.
I have a ford transit custom 2014 and ambient lights, radio and alarm are not working if the ignition key is not on position 3.
Can I get some help?
Hi great video, they have made these vehicles do hard to work on. I have a 19 Kia Sorento, LX V6 AWD, when I open the doors the interior lights don't come on. Tested the Map/Dome light assembly and it's works 100%. What would be the next step, replacing the BCM or is there a designated relay for the lights?
Take it to someone who knows what they’re doing- electrical issues are best diagnosed by a professional. These newer cars are so sensitive with their complex wiring and sometimes dozens of control modules that its not worth saving a few bucks trying to do it yourself
Check the harness for the driver's door. Pull out the bellows and look for broken wires. It's a common problem. Pull the wires one at a time using your index finger. If the insulation stretches, the conductors are severed. Repair wires.
Thanks will check that out. The bellows you mean the rubber covers that hold the harness in the doors?@@Wildcat5181
Could it cause issues with the climate control on a Ram? May be HVAC module since screen says climate off and stays off yet fans work. I noticed weird issues like cruise stopped working then started working a day later. Hl says out but on. Did get the code that BCM lost communication, no HVAC code
Well explained! Thanks…….
Thanks for the low down
Any one can help me Sir, my wiper spray water is not working, is it because of the BCM? I have searched and tested the fuse, all are working fine
This was very helpful!
my nissan cant detect my key fob and I cant start the car. no lights on dash except the key and step on pedal. I suspect its the BCM...HELP
Try new battery in fob first
Plug your fob into your dash. Dead battery or not. Should still start the car. Fob slot is about knee level on driver side
Did you ever figure out what the problem was ?
Can the bcm lock your electrical back brakes impala lt 2014
Hi there, I have a 2019 Chevy Equinox which has all sorts of intermittent electrical issues such as some or all power windows don't work for days and sometimes all work, sometimes the driver side door won't lock/unlock and sometimes it does, sometimes the interior lights works and sometimes it doesn't, sometimes the display changes from audio to android phone and vice versa and sometimes everything seems just fine and so on and so forth. This has been happening on and off since almost a year now after I bought this brand new. All fuses and relays seems good. Neither the Chevy service center nor auto electrical technicians can figure out the problem. Already spent some $$$ and these issues still remain, though the car drives great otherwise. Could this be the BCM issue or something else? Please advise. Thank you.
Damn dude I am having the same problems with my 2008 Chevy HHR . I was beginning to think the car was possessed. The problem is the car runs great.
@@grumpyoldrockers1048 LOL, the invisible predator in the car is getting energized by sucking up the charges. But jokes aside, after carefully watching a lot of videos on TH-cam, I bought a multimeter and a test light and am about to diagnose the culprit myself in piecemeal by first checking all fuses and relays again and then the connectors, modules, harnesses and finally the ECM, PCM. Have you found out the problems in your 2008 Chevy HHR yet?
@@earthlycreature8772 oh yeah I know what the problems are. OK the main problem is the ABS and traction light are on. Did a live road test and the wheel sensors are great and all four work in tandem and are giving great readings so we know it’s not the wheel sensors. We clear those lights and we can drive it for miles and miles. Not a problem they won’t come on. Soon as I turn the car off, and turn it back on, Bam the lights come back on. The rear hatch lock won’t open. But there is an empty fuse in the main fuse box number 11 if you put a fuse in there, the hatch will open and close perfectly. But that is an empty fuse slot. But somehow it bypasses the BCM. Same thing with the rear window wiper, it doesn’t work at all, but we jumper the relay and the rear wiper works perfectly! Then I have an intermittent Door window switch. Sometimes it works sometimes it doesn’t. all these things as described in this great video are controlled by the BCM. I’ve checked the BCM for faulty, wiring or ground problems, that’s not it. I’ve got a bad BCM.
@@grumpyoldrockers1048 Please share how you made out? I am getting ready to Get a refurbished Pre-Programmed BCM for my 2010 Impala.. I took out the BCM to get the Part number off it and opened it up to look at the board and It looks Perfect.. So I am hesitating on buying the newer one.. I have been having intermittent No Crank No Start issues the Usually Start with Warning Chimes, Service Everything Messages, Gauges go Crazy back and forth, Door Locks on/Off Constantly, Shifts get Rough BUt not Limp Mode and sometimes it actually goes into limp mode.. Once I shut it off for a while then begins a No Crank No Start... Most of the times a can Disconnect Battery and then it gets back to normal.. Took it to dealer and they got me for a $800 for diagnosis fee and New Starter.. Worked for 2 days and No Crack No Start.. Finally get it Started and Limped it back to Dealership.. They had it for 3 weeks and Couldn't recreate the problem... They were leaning towards Bad BCM and wanted $450 for new BCM and wouldn't charge me for labor... I took it back from them and it worked for 5 days great Until this Past Saturday... Any Help from anyone would be much appreciated.
Would the BCM have anything to do with parking lights staying on all the time?
What vehicle do you own?
Did you ever figure out what the issue was?? Im having problems with break light and rurn signals not working. 😔😔
hi... good explanation but there are things I don't understand, my 1998 Buick Regal, the Power locks don't work, I only opened the driver's door with the beeper and the trunk... but the beeper broke and I bought two new but I can't program them, even if they work half as before, because the power locks don't work...so I got the electrical schematic of the system and I checked it completely and it seems to be fine, the actuators are working and have current, the same with the switch the doors... when you press to open it sounds a click click in three little boxes that look like relays and at the same time in the circuit relay it also clicks....so I bought a new one and it continues doing the same thing, I put the original one on it back and now it closes when you press to open and when you press to close it sounds three bells...also when you put the car in Parking it locks instead of opening...it drives me crazy and I don't know what to do...I know this post It's long but it seems to me that you are a person who can help me... a strange thing is that when I move the relay it stops working and clicks and then I move it from new and start to close...
.thanks in advance for your help...if you have a email is better but is up to you.
Did you readmy problem...please let me know
Can anyone give me some insight? I have a 2019 GMC sierra my left side DRL stopped working when my truck is in park but my right side does work also when I put it in drive the left side DRL does work? Can anyone explain
hi i have problem with my head light, they are always on even when switch is on zero and cant connect to central electric with diag is it possible that my bcm is at fault? i changed my comfort module for new one same issue.
My bcm is faulty my bcm has pink colour code but can I replace it with any other colours like green, blue, yellow etc will there be any compatibility
I sent my car to the dealership mercedes...and they said . That I have a bad cluster...so I change the cluster..and I still having the same problem...and they said that they need to continue the diagnosis...and the cluster price was 1800 dollars...so I need to go to your place

Got a faulty bcm for Kia seltos 21 car was not starting,
After replacing the old bcm to another car started.
Old bcm if you kind of bended it would start.
How can I identify the fault any advice please?
do you need to reprogram the bcm or is it plug and play?
Is your shop located in the Los Angeles area? I was told I need a new BCM for my son’s Civic. Thanks
Could one of these be the issue if my obd2 port not communicating?
How about transmission issues or not engaging in a 2014 jeep Cherokee, and the only dtc is a body control module one.. replace bcm?
Did that fix it?
Short & sweet, nice vid! I’m considering 02 Jag XK8 but windows, rooftop and seats don’t work. Seller is saying it may need new control module. But I heard programming it can be difficult. Any suggestion or experience with this? Thank you
Match up part # and find someone with the correct programming scan tool to do it.

My car all of a sudden electric windows ( only front ones ) stop working my windshield wipers stop working and my ac all at the same time including my key is sometimes not even detected on my bmw f30
Good
I have complete and total power failure on a Dodge Journey 2011. It's not the battery nor any fuse (and I'm very certain; I'm a motorcycle/aircraft tech). Seems like the BCM is the only single point of failure that could cause a complete failure of all things electrical when everything was running just moments before, right?
Yes, I am CERTAIN it's not the battery, alternator, or fuses. It gets annoying getting advice from the student-level every day.
The only other suspect I have in mind is the TIPM but that's an even bigger hassle to replace, it sounds like.
Sadly VW cloud the issue by having a control module in the doors as well as an overall control module (comfort control module). Makes it hard to know which is faulty
Dou you have to reprogram the new used BCM on a 2010 Nissan Altima? If yes how do you do and how much it costs?
Yes
i have no dash lights no blower fan no windows no horn no signals no electic seats no seat heatser 2012 golf tdi hatchback. my radio works and my alarm goes on at random times. is this my issue
Is BCM something a local auto shop can repair?
It's not difficult to replace the BCM. However for some vehicles, the BCM must be reprogrammed after replacement.
sometimes, the pins can be resoldered as a DIY. On Dodge Caravans, for example, the plugs on the BCM (and instrument panels) sometimes get cold solder joints that crack over time with vibrations.
Thanks
Thanks allot
My RPM and Coolant guages like to go up and down. Even at idle. Maybe BCM
Does the BCM affect TPSM?
New sub here thanks
Thanks bro 😊

Good day Mr. I had a Mazda Capella automatic motor 2.0 lt, year 2001, here in south américa it's 626 Millenium and the cabin lights fail and radio, I was restore the 10 amp fuse, and radio start work but cabin lights don't, can tell me where it's the BCM located, and where I can buy a same parte by internet, thank you for your cooperation y explain.
Can a failing bcm cause the engine to run poorly, like misfire, run rough, almost die if you put it in gear? So basically can a bad bcm module disrupt the can bus signals such that the ecm can’t operate properly?
I wouldn’t think so.
@@dirtcheapmedia3390
It absolutely can!
My car was sputtering like it was gonna die!
All gauges went haywire! Lost power steering and the power locks were going up and down!
Had the BCM replacement under warranty!
But now it's happening again with no warranty! 😂
May need to replace a SECOND time!
Absolutely!
I had to replace mine due to:
Sputtering, loss of power steering, gauges going crazy AND Power locks going up and down by themselves!
Good Luck to you Sir!
