Well, I finally tackled this job myself over the weekend on my 2003 C5 z06. Worked on it on a Friday & Saturday to get it done. Not gonna lie, it's a beating! The easiest part of the whole job is the soldering you do on the circuit board. Removal of the EBCM, removing the cover for access to the circuit board and then re-installing the EBCM back in place is the beating! I'm 65 yrs. old, too. So if I can do it, almost anyone with some patience, common sense, mechanical ability/experience and a little circuitry soldering experience can do it. It actually WORKED!! Everything cleared, all the warning lights that were on went off and now my ABS, traction control & competitive driving modes all work again perfectly. Like I said, it is a beating but, not near the beating of $1700 to have the job done. Thanx, RUclips!
you're welcome
@@chemicalspore - And thank you, too for posting this video.
Very good and informative video. My 2002 Z06 had similar failure indications. The dealer thought it was the EBCM, but it had Steering Angle Sensor codes as well (C1287 and C1288). Speaking with Brandon Hite of ABS Fixers in Missouri, his educated hunch was correct - I put the car in the shop early yesterday morning to have the Steering Angle Sensor replaced, they were done by 2:30 in the afternoon. The new sensor fixed the problem. Drove it home and the console Traction Control button works normally and allows me to go into Competition Driving and all that good stuff. It toggles correctly. None of the problematic DIC indicator messages nor caution lights came on.
I appreciate Mr. Hite's able assistance and being honest with me, when he could have taken advantage of me and had me send in the EBCM box. It all works now correctly.
That is awesome. It feels great to have the issue taken care of. Thank youfor watching
Nice work. Also see the wheeler Dealer C5 Z06. They have a good way of checking with a multi meter. And proper handling of circuit board.
Well done bro! Thanks for the video! I’m almost ready to tackle mine now.
let me know how it goes
Thanks, I just did this on my 2000 Buick La Sabre. The module looks identical to your's. It was hell to open and I saw no solder joints that looked bad. I resoldered all I could reach, cleaned with CRC electrical cleaner and resealed using black RTV. I thought I'd wasted my time but the light reset and hasn't returned after about 50 miles. I still don't know what I fixed. I didn't find your video before, I guess, because I searched under ABS an not EBCM.
Thanks for your video. Just did mine and it worked. It would of been a lot harder if I didn't watch your video. Again thanks for taking the time to do this video.
Awesome, good work buddy
Nice job. Gonna need to save this if I ever have to do it myself.
It's easy bro.
Wife, "Why are you always buying more tools?", Me, "I just saved us $500.00"
You said it brother
This is by far, the best video on this i've seen. Thank you for getting in there and getting a closer look at the ebcm. I just bought an 03. Picking it up Saturday. I'm pretty sure this needs to be done. The service vehicle soon message is on and I can't remember the other one, i think it was the traction control. Anyway, I have to drive it home 3 hours from Virginia beach back to my place in Delaware. Again, that you for the video, very detailed!
I appreciate that. Thank you.
@@chemicalspore I finally went to do this today. The middle bolt on the right wont budge. I think my t20 is too wide and shirt to reach that one ugh
Getting in those small spaces to see what is going on can be a pain. Try getting into yoga, than you can bend anyway to conform getting in those weird spots. lol
video ok
I know it's been a while. But my service active handling comes on sometimes. Esp if it's cold. Could a lose connection cause this?
Do you see that "blind hole" at 4:05 next to one of the mounting holes? you can drill that with a #7 drill and tap that hole with 1/4-20 tap. You then thread a 1/4-20 bolt through there which will go right through the case (without damaging anything) and will apply pressure to the cover plate whilst you start to cut away and pry the plate from the case. You continue to thread the bolt as the cover plate loosens and you continue to cut away at the RTV until it completely comes off. This will save you a ton of time/effort in trying to remove the cover plate. Thanks for the video!
That is nuts, never thought of that. Thank you for watching.
@@chemicalspore I did that and it worked great saved 2k
just did mine. IT WORKS!!!! Good Video!!
Thank you. Subscribe for more content
I'm having that problem now I'm definitely going to try it save some money
Great video buddy
thank you
Great channel buddy
I just subscribed to you as well. Yours is pretty awesome
@@chemicalspore cheers buddy all the best ...
You sir are amazing I just fixed her up.
Cheap and easy repair. I am happy that it worked out for you. Keep on keeping on.
Hell yeah brother!
Very nice informative video bud..... Nothing like a job you accomplished yourself.....
Amen brother
Great video. Just an FYI on the back side of the housing is a hole about 1/4 inch in diameter. I'm not sure of the actual diameter. Anyway, there is a clear pathway from the hole to the cover held in place by the four screws. You can drill and tap that hole for a fine thread bolt long enough to push against the cover plate as you screw it into the housing. Go slow and use a razor blade to carefully separate the cover from the housing. That is much easier and causes no damage to the unit.
I wont have to worry about that anymore. I no longer have the car.
Good job! Thanks for this upload... Thumbs up from me... Stay safe... Rico
You have had some issues as well?
@@chemicalspore - Not yet, knock on wood, but it's a good video to have just in case I ever do... Thanks again... Rico
@@Ricovette subscribe if you haven't. Thank you
I have the same issue. .. thanks ill fix on my own.. also replaced outer wheel bearing easy remove entire arm
Awesome job.
Wish me luck. Diving In
Gitt R Done. Also, subscribe.
Welp I'ma try it in my 02. I'll post when I'm done
Let me know how it goes
That’s was the throttle body actuator isn’t the throttle position sensor on the other side ? And I hope this works for me !! 🤞🏻
Did you fix it?
Hi great video, thank you! Just curious how many miles were on your 03 when you repaired the ebcm?
Thank you. I am going to guess it was around 60 thousand miles or so
Im on the 2000 corvette and everything is different, no wonder i couldnt folloe along lol
That sucks
5:20 that is a lacquer they put on the board to protect it. totally normal.
Cool thanks
hanks for video - unfortunately my C5 EBCM is not that model and taking it apart shows a diffeent circuit board. Can I ask where you got the info to do this in the first place?
Ive done this before on my body control module with my Camaro. Some the Soldering points loses its connection.
I'm pretty sure there are six (6) T20 screws holding the EBCM on.
Read the description
I have the same lights intermittently coming on. The code I pulled was a TCS-C1242 (pump motor ground circuit open). Is this the same code you had?
I am not sure. I never checked the code. Have you changed anything electronics or any fluids on the car?
Yes. The car had sat for awhile and the battery died. Replaced it, and now this is happening
Is it locating under coolant pipe? :D when thermostat or anything in cooling system is changed its possible that coolant goes in wrong place
It does sit under a coolant hose.
Would a bad EBCM also throw a 1287 and 1288 code as well? I am getting 1214, 1287 and 1288. I would think since the ebcm is the "brain" the steering sensor may be getting false readings? 02 z06 only 24k miles lol..
It does not interfere with the steering, only abs and traction control.
Cool flip flops
I'll send you a pair
look like a job well done to me
I appreciate you. Thank you for stopping by
I COULD NOT GET MINE APART TO EVEN ATTEMPT A DIY , SO I SENT IT OFF TO ABS FIXER. $150 QUICK TURN AROUND.
I HAVE HEARD IT IS USUALLY A $ 2 PART.
It was not easy to do. Some solder, and it was good to go
Are the six bolts removable from the top or underneath? And how difficult are they to get to?
You can do it from the top. Not that hard, just got to have patience
@@chemicalspore Thanks, may attempt it this week.
@@DanPattonFotoZ it's not that bad
@@chemicalspore Well, went and checked mine and it has 4 bolts. My Vette is a 2000 and they are different. Been told buy a long time Vette tech that they cannot be rebuilt so I can't decide whether to remove it or not. If you or anyone else have heard different, please let me know. Thanks!
Will this fix th famous abs humming problem the Chevy avalanche has buy resolder everything
I am not aware of this hum you speek of. Sorry
Can you drive the car with this removed? My 01 Z06 has this issue and i want to get it rebuilt but dont have another car to drive...
Im sure you could but it will still throw the same codes
you can drive it .... u can do it your self just done mine ,about 2 hours
Would anyone have any idea why when I run the code for TCS it pops up “No comm.”????
That might be a gm question. Call 1-866-522-9559
No com. Means no communication
Hi, i have a 2003 c5 corvette, and sometimes appears the error 28-TCS C1296H ( entering in the manual diagnostic, it appears as H, History). Do you think that opening and cleaning the electronic PCB could resolve the problem? Regards from Italy.
This car is 2003 as well. If you are having the same issue, this should resolve it if you follow this video. Cool that you have a C5 in Italy
I lost and cannot find the middle torx bolt while I was putting the module back in. Does anyone know what bolt this is so I can buy a replacement?
Call a place called "coastal corvette" +1 321-269-4995
Would it be the same on a 2000 corvette?
I am Not sure but I feel the anatomies of electronics or the same from 2000 to 2003
Bernie, My 2000 has 4 bolts and I have been told they cannot be repaired. If you find out something different please let me know.
Can the 99c5 be repaired? I heard they were not repairable
If you can get the casing open, I do not see why it wouldnt be. usually it is some bad soldering on the points that makes it lose connection. But I have also heard that the 2001 and back Vettes were not fixable.
I hate that module I get messages until I turn off traction control then everything's fine so I just always turn it off
Yea, they are a pain. Thanks for watching
Does anyone know if it will work on a 2001 ls1 camaro I believe it will?
I have a 2002 Camaro that I have yet to have issues with. I am sure if you pull the EBCM apart and look for bad solder points, you could refurbish them.
@@chemicalspore
I pulled the module off but there is not back plate as noted in your video it is just a plastic housing with no screws that I can see so I'm not sure if I should pry it off and end up doing more damage to something. I can seem to find any info or video on a camaro ls1
Mine is a 07 trailblazer, the traction control light comes on, and it applies the brakes and heats the rotors, anyone seen this?
I have not. You might want to call gm
@@chemicalspore Thanks, maybe I will get their opinion before I take it apart.
@@Cylinder-Pro-aliasWonderdust could be alot of things. Maybe you have a crimped hose or line. Check your fluids, the calipers could be locked up.
@@chemicalspore one caliber is new, the master is new, I recently bought this suv and put the engine in, they lost a puck out of one caliber and bleed the system off, then I could not get the pump to prime, had to crack the tubings at the pump even on the new one to bleed it. Anyway, 500km later, starts setting the traction control fault light, then I notice the brakes, (both front for sure) dragging , so it is escalating.
@@Cylinder-Pro-aliasWonderdust have you scanned the codes?
Can you run the vehicle with that part off?
I'm sure you could
Hey got her put together worked great. Thanks for the video. The grey clip for the big plug came off and cant figure out how that goes on... might just zip tie the plug. Anyhow your video was very helpful and to the point
what relay number？
T72M5D・・・・・・・←？
I do not know
BUT ... WHAT is on the other side of that pcb? Leaking caps?
I dont understand the question.
Why did mine have six bolts?
02 corvette
I messed up. They are all 6 bolts
what relay no?
T72M5D・・・・・・・・←？
I have no idea lol
Ideas on best place to buy a replacement one of these, or who can repair it besides a dealership. I sound like a moron, but im a driver lol.
I really do not know. You could try an electrical shop and show them a video like mine. All it is some soldering and you are good to go.
@@chemicalspore Was it easy to obtain the part, its not obsolete?
@@davelyons9959 i just took it out and repaired it myself. Not that hard
@@davelyons9959 Parts aren't being made on older vettes. Not on mine, it's 2002. You have to look for refurbished. If you get someone else to replace it, keep your old one and try doing steps in this video. I don't know why mine has the TCS code come up with check abs, check traction control, check active handling with only 47,000 miles. That just sucks.
Are 1999 C5 that different??
I really have no clue on that. I have not seen one for that year. I heard that it is but I cant see it being to different.
@@chemicalspore The forums say non repairable. I hope not.
@@TeamLazers holy shit
@@chemicalspore yeah, that's $1000 problem now.
@@TeamLazers send me pictures at chemicalspore@gmail.com
man oh man would i be sad if mine was automatic
My camaro ss is not. Has 110 more horse power than the vette
The dealer wanted to charge me 2000 to repair this, wtf.
Ass holes

@@davelyons9959 There are people who can refurbish it for you on ebay.
