- This mint 2010 Chevy Colorado is fussing about the ABS and TRACTION Control system.
The code set is a C0252-"Active Brake Control Sensors Uncorrelated"...
Huh?
After digging through the service info and performing some checks, it becomes clear that some parts will be required to fix this truck.
Bonus Cluster Repair footage included :)

Ivan - Auta a dopravní prostředky
I love these repairs. The mental challenges are a heck of a lot more fun than the physical ones
Shaking a yaw rate sensor makes me think of Scanner Danner's air bag deployment video just a little lol
I was thinking the same thing lol
BOOM!
Only if it was connected to the airbags...
Yeah, *SD* got a wake up call on that one! LoL 🤣😆
He admitted that the reason it deployed was because I had manually grounded the module (for testing purposes), usually as soon as you remove the module from the bracket, it disables itself since it gets grounded for the chassis, the engineers didn't think of Danner using a jumper lol
Me too..
The soldering iron is awesome... I bought an adapter for Dewalt batteries... I have a ton of Dewalt tools and chargers so it made sense... The battery lasts forever and the iron is a big time saver and precise... I give you a thumbs up for the recommendation... Good video - I didn't find myself "yaw-ning"... LOL... PS - take a trip to New Hampshire....
Indeed. The TS100 is my primary soldering iron. It runs great on 18V Li-ion batteries. But also on 19V laptop power supplies.
I flashed alternate firmware into mine. It now has a battery indicator and a low-battery shut-off. You can set in the settings how many Li-ion cells your battery has in series. That would probably be 5, for your DeWalt battery.
it would even run on a car battery, if need be.
I don't get that people would complain about that iron. It's incredibly versatile and it can easily compete with low-mid-range soldering stations.
I've driven GM cars for a long time, but Delco or Delphi electronics have always been notorious for cold solder joints. Being an electronic tech, I've repaired many radios and other electronics on these vehicles. Great work Ivan!
I wounder why that happens
Same here, I repair GM clusters for a living
Ivan, you're getting better and better!!!!
I love these case studies. I'm a one man show so I can't afford to lose time on case study type repairs. Troubleshooting the problem like you do helps me return the vehicle to the customer much faster and keep the shop flowing.
Gotta do donuts to properly check yaw rate sensor.
In a related vein, on my 2007 Trailblazer the steering wheel position sensor was a known issue. If I parked with the wheels a bit askew the Service Stabilitrac light would light up on startup and the system would be disabled. Shut the truck off, straighten the wheels, start it up again and the light would go off and Stabilitrac would work normally. I got used to always parking with the front wheels very straight.
You know a man is talented when he makes his job look easy. Once I tried to find a bad ground, ended up burning my entire town to the ground 🤷♂️
That is the most thin looking soldering iron I have ever seen. It looks so comfortable to use as well as the ability to get in tighter spaces. Also the need for a new ebcm in such a new looking truck (2010) seems like a real quality control problem.
Probably bad solder joints in it too?
@@dans_Learning_Curve You are probably right.
OnStar: are you alright sir we determined you have just been in a blender. Would you like to pay 19.95 for the subscription for us to send help?
I enjoyed the board repair and Ivan certainly has job security when everything is electric !
Great video, great technique in verifying the need for a new module. Thanks for showing the process of downloading and using the reprogramming software. I appreciate the bonus footage and the suggestion about the ease of using the battery powered soldering iron (which I believe replaced your old butane-powered one) to make these repairs to a circuit board - there are a lot of cold, cracked solder joints out there, which can be easily reflowed to give new life to tired cluster control panels and radio/cd power supplies, among other things.
Thank you!
Like your soldering iron - would have loved to have that in 1965 when I started in electronics. I still suggest adding some more flux when you re-solder those pads or anything else. The standard 60/40 rosin core solder does not have enough flux in it to get a really good flow going. I know it looks good - shiny and all - but, it is the connection between the solder and the pad that you can't see not the wire and the solder.
Great suggestion. What specific flux would you recommend, and where can I order it from?
You can just 'Google' it - the one below is good because it has a neutral Ph and is non-corrosive. Do NOT get the cheap ones. If you only solder a little this one should last yo many years.

@@skiplazauski1497 Thanks. I immediately placed my order for your recommended flux.
Great diagnosis! And fix! But you said no parts required on the cluster! But there 'was' solder lol. Some soldering required, hahahaha 😆🤣😂 just ribbing you, ivan! Great video. Many thumbs up!
"In progressing" my Launch says exactly the same thing! 🤣
I usually use a laptop power supply with my TS100, but for those times I need to be portable, I just built a connector that plugs the iron into my 12v power tool batteries. The TS100 is by far the best bang for the buck iron that I’ve seen and used. My Hakko soldering station collects dust on my basement work bench now.
THIS IS WHY I LOVE OLD SCHOOL TRUCKS!!!!!
Great job, Excellent troubleshooting, and repair.
You had me cringing every time you shook that yaw sensor . Scanner dinner did that and BOOM 💥 ALL the air bags went off ! I thought we were gonna hear an oh sh!t
No scanner danner did not shake the yaw rate sensor… wrong…
He shook the AIRBAG MODULE, not the yaw rate sensor. Perfectly fine to shake yaw rate sensor all day
@@mikesabin8568 actually he turned the airbag module thenn re grounded it and boom 💥 thought the car was rolling .. I was just busting his balls 🏀 but thank u for attempting to tell me the rite thing. 👍👍 it just reminded me of it a little bit .. I just watched that video again last week 😂
To quote another popular CZcamsr " expensive piles of plastic and wire! Great vid, Ivan! 👍
Your knowledge on electrical components is unbelievable! Keep up the good work.
Liked
Thanks for the video!
Life is a learning curve?
HINDSIGHT IS 20-15!
Your experience is showing!
*Nicely done!*
Ivan you're second to absolutely none!!!
Nice video I wonder if the detail guy got a bit to wild with the vacuum nozzle under the seat and pushing that yaw sensor over.
You very well could be correct!
I did hear a story where the detailer got went super suds mode and inadvertently destroyed and ECM or some other crucial module on a BMW that was under the seat. One or two broken bottles of wine messing with stuff also.
You have to love GM SPS. LOL. I got my J-Box Ivan to replace that junk I had. Used for my GDS2 but not for programming yet. Have a good one my friend.
Great repair great video. Thanks 😊
Great job Ivan...I just wonder if that truck had some aftermarket suspension installed throwing off that level sensor.
Brilliant job Ivan 👍
Ugh. GM ABS is such a pile. I remember Kieth has a video about how aftermarket scan tools can't read GM steering angle sensor live data correctly. I've certainly found that to be true!
I was using the Verus Pro once and I could not read the angle steering angle on a GM vehicle, I didn't think it would not have that data. I should have tried it with the Launch Pad II but didn't think of it. I almost suspected the damn module as well since I had steering angle code.
Had a 99 Deville that suffered "Service Stabilitrak " off and on ... probably the same type of problem. Dealer could never find anything wrong. A key on-off cycle would cure it for a least a little while... Had to get rid of it soon after as more and more electrical gremlins were poking up.
Nice fix again Ivan 👍👍👍👍
Do you have a Amazon tool page with the soldering iron on it. I want to say you did at one time. I work mostly off a service trk and a battery powered soldering iron would be useful.
Good job Ivan. Thanks!
Great Video as always!
A little electronics paste flux dabbed on the joint before applying heat, would really help the solder re-flow
great diag and fix Ivan
Lots of fans of the ts1000 iron. I have been meaning to get one.
Most of those little jump boxes have a 12v plug if that's what the solder iron uses.
5v USB, it may negotiate more but it's gotta start at 5 via USB.
i love the videos with you and eric o its really cool i also love your videos
Wow. Ivan. Thanks. For the. Video 🙏🏾🙏🏾
Another awesome job!!!
Amazing diag! Thank you sir!
From the moment I saw that steering angle sensor come alive on the new module, I was questioning if you ever actually needed to replace the EBCM in this vehicle. Did you ever check the steering angle sensor while you were driving the car on the old module? If it was dead while you were driving, then the old module was definitely bad. However, if it was alive and/or you didn't check it, we would never know whether the old module was faulty, or just needed reprogrammed.
Remember, the service information said that the EEPROM in the EBCM saves checksum data based on the yaw/accel sensor inputs, so even if the lateral acceleration sensor was the only problem in this vehicle, you would have needed to reprogram the old module to delete corrupt checksum data from the EEPROM. I definitely would have attempted to reprogram the old module before replacing it.
Nice job and video like always
That is a very nice-looking truck!
I wonder if reprogramming the original EBCM would have reset/fixed the issue.
Great video Ivan!!
A checksum error almost ALWAYS indicates corrupted data or a defective chip!
Good luck pulling that data and diffing it with the tools at hand.
@@anonymic79 I agree with Lustfulvengance, But it could have been a simple writing error rather than a defective chip. tiring to reprogram it first would have told us that since the GM program that was reprograming the module would have reported a write error.
Ivan is the best!
Do you remember when cars needed only air, spark, gas and a drop of water and oil? We are falling down deeper into the rabbit hole.
Hi Ivan, I agree the ABS module was the trouble but, before I would have condemned the module electronics I would have tried to reprogram it since once you buy the reprogram process from GM you can use it multiple time on a new module or existing module in the same car. I have a feeling something changed in the modules software since it would not even let you clear the error message.
That's a good thought! Should have tried it for kicks 😁
Hey Ivan,hope Pine Hollow has the holiday weekend off,watched the TS100 in action,again,time to pull the trigger,is there a link or promo on Amazon. You really do fine work! Have a great 4th!
Man, the used car market must have ballooned like crazy if they think they can sell an 11 year old Colorado for $17k. 8:52
Well optioned new Colorado Crew Cab is $35k. Unless it’s 4wd, then it’s even higher. 😳
Holy hell. I just did a search and if you want a 2010 at a price I thought they went for it would have to have close to 200k on the odometer and minor rust. You'd still have to be crazy to buy one though.
My father's 06 with 115k is a rolling fire hazard with all the burned/melted garbage electrical shit I've had to replace.
... and then there's the defective cylinder head that doesn't seal at all around the intake valve in cylinder 2. Its run poorly for about 30k with a constant shake under 1500rpm.
The 2018 Colorado with less than 15k miles I drove at a job I quit stranded me 3 times because of electrical failures.
In short, GM can kiss my ass.
Welcome to 2021
Awesome video!!... thanks man!!👍👍😎
Sir, never move a safety mitigating sensor or module whilst powered, never power such unless it is secured in it's designed location. Failure to observe such can create conditions that require the module or sensor disable, in some cases permanently...
Yaw rate is the rate of change in yaw angle not the angle. If you keep it still it should be close to zero BUT a small offset is caused by the rotation of the earth. If it is not horizontal it gets crosstalk from pith or roll. Acceleration should be zero if the car is stationary independent of the orientation. (edit: in the lateral direction, if you turn the accelerometer axis in the vertical direction it should read + or - 9.81 m/s2, [32 ft/s2] the earth gravitation)
Ckecksum error Check some of this and check some of that.
Accelerometer, Steering Position and Yaw Rate stuck in Gimbal Lock.
Ivan replaces module, fixes gauges and vehicle continues it's journey
Toyota and Lexus had a very similar issue in the mid to late 2000’s models. Wonder if they sourced from same Chinese manufacturer.
Note to self: Look again at the Ford and Toyota truck quotes. Forget Chevy. And buy the extended warranty. Why make a science out of a simple steering system? I’m a retired Penn State/Pitt EE. That whole setup makes me cringe! Great video. You tamed the wild beast!
Since the initial DTC was a CRC error, did you try to program the old module?
talented young man
the more I watch your videos, the more I know I don't want new car
Ugh, I just bought one. Time to buy a new scanner.
On a used car maybe it would be a good idea to check and see if it had the proper EBCM and software for the truck. Who knows what has been changed and why. Auction cars are always a mystery. Sometimes potential buyers will sabotage them to get a better price by making them look like they have a problem so less people will bid on them.
I remember an SMA video where someone had swapped an engine on a similar age vehicle, and also snaffled the wiring harness for the replacement engine. While everything fitted correctly there was a circuit change between the models and the engine wiring harness was sending the right signals to the wrong places.
Took a while to work that one out...
Found this video looking for another ABS issue. It's a customers car, an 2006 Hummer H3, so a similar setup as this one. I have an ABS and Trac control light turned on in the cluster. However there is no check engine light turned on, and there are no trouble codes in the PCM or ABS/EBCM, so I'm a bit stumped on this one. Looking at the extremely slow live data for the ABS module, it seems that the right rear sensor is not reporting. I have replaced the sensor, and checked wire integrity between the sensor and the ABS module, and I am reading a small amount of bias voltage at the sensor end. Not sure if I should call the ABS module on this one, not sure what else it could be. I find it odd that there is no trouble codes in the ABS module, not even pending or otherwise.
Odd that it changes sitting in place. Yet the steering angle stays at zero.
Let's diagnose this....... together
Wow that’s really amazing you do great work how much would something like run me at the dealer? My TC light is in on a 2011 Colorado…. I gained some insight, great vid 👍👍
Well done
another great one !
backwards stuck tach, I wonder if the magnet flip trick is all it needs lol
**never mind I just realized it was at zero/working earlier in video, bad solder joints it is!
Man, a 2010 GM vehicle with cold solder joints? Unsurprising.
I had a 2001 Malibu. The A/C control head failed twice due to cold solder joints. The first time, it was under warranty. The second time, I reflowed the control head myself with standard 60/40 leaded solder. No more problems.
I should have done the same with the BCM. It would click the hazard relay due to bad solder joints. It wasn't until after I'd traded in the car that I realized what the trouble could be.
and this is why i like my 99 buick century.... 9 times out of 10.... just pop it into nuetral, key off, start, drive
it resets and works for another 500 miles
.
but the wires do break clean on the rear (easy repair)...... and get oil soaked and the insulation falls off on the front sensor wires
.
and cheap scanners will read the data and codes just fine
Great video Ivan! Thanks for taking your time to do the video ! Hey is that a Bosch MasterTech one or two Ivan?
Gen 1 Mastertech
@@PineHollowAutoDiagnostics thank you Ivan
Hey quick question to see what you think or maybe have seen this problem before? 1995 chevy K1500 5.7 signal wire on 2 terminal coolant temp sensor and map sensor signal goes to 5 volts after closed loop then pours fuel and barely runs.
Great job
I had this happen on my truck. GM replace the hydraulic manifold thing? Reset it all in July 8 2021- $980 , it Work perfect, then just this month near July 10th, all lights came on again. I did the push-accelerator 3 times reset. Light went off for 2 days then came back. I cant get them to reset again. What other issues could do this if parts are new? I look at the 2 30 amp fuses, how do you pull those things?
Have you tried the Milwaukee m12 soldering iron?
Brother. I really like your videos but if the steering angle sensor reads zero I'd check that first.
For sure... But no code for steering sensor so not sure what was wrong with that data
@@PineHollowAutoDiagnostics I watched the whole video. You made the right call. The codes can sometimes throw you off as you well know. I'd have checked everything you did but just in a different order. It's strange that the steering angle sensor only came back when you drove it. Weird. Great job Ivan. Love your channel.
Having the same problem with my 11 equinox,just got a 919e scanner,scanner shows values but you dont know what is a good or bad value instead of letting u know.
I work on those ABS modules. Total pain in the ass and commonly can't be repaired!
Honestly makes me think very poorly of Bosch and the like
My longitudinal accelerometer sensor signal stays pegged...is it part of the YAW/lateral sensor under the seat?? I cant find any info on the longitudinal sensor.
I have a 2012 chevy colorado 2.9. Runs great till it warms up and I stop. Then it just dies no clunking out like it's stalling or nothing just dies. Fires right back up let it set for a minute then it dies again. Can fire it back up floor it all is good till I let off the gas and let it idle and it dies. Any ideas. They say fuel purge canister valve and an ac delco oem filter can be causes on the 355 nation site or a map sensor. Starting with oil and fuel purge valve. Just paid 3700 to get timing done as well
Hey Ivan, What is the model number on that Bosch pass through device you were using in this video? I need to get me one of those ;)
Whats sps and when do u usd it? Never seen u showing it. Can u not use ur scanner to program?
I have a question concerning the ABS/Traction control on a 2013 Nissan Sentra where there is no DTCs and yet the traction/ABS and sometimes Brake warning lights come on, and most times it happens before the car is even moved. Have you ever seen this type of issue Ivan? Just curious as I would think that anything that causes the lights to come on must start with some sort of major fault and a resulting DTC.
What kind of laptop is that are you using
a GM with a bad ABS module, I'd have never guessed! LOLOL
i had bothservice stavilitrack and then aservice absmessages on my 2008 sierraafter much head scratvhing i foun the fuses were bad
Dude how the hell did you pull that ebcm connector off
the thing about the yaw sensor is you don't know how level the ground is. Even if you're in a shop
👍 good job
Does your Thinkcar Thinktool Pros Scanner work with GM OBD 1 Trucks? I was reading up on it on Amazon and it does show an OBD 1 connector. I looking for one to work on GM .65L diesel engines. Thank you
Nope OBD2 96 and newer only 👍
I'm confused!! You had the acceleration sensor in your hand and tilting it changed the g"s that it was reading? Tilt has little to do with accelerating unless the weight inside is not balanced by the opposing restraints? I don't get it. Not moving should yield "0" not -.5 or anything else. Making it change value should be determined by starts and stops (shaking). And yes. That guy must be responsible for Air Bag deployment (with other sensors?)
Where did he order the ebcm from ?
Since both ecbm showed 0 steering wheel angle, I wonder if reprogramming the original would have fixed the problem... NPR.
Perhaps. But replacing the module is the most reliable solution 👍
Hello & thanks for such great videos. I have a situation where my 2005 Colorado goes into "Reduced Power" and then shows the message "Traction Fault". Would you happen to know anything about this? I have gone to soo many places & dealers & they can't figure it out because they can't replicate the situation because it only happens randomly. So when it happens, I get stranded for a few minutes, I shut it off, wait a few minutes and then I'm able to get going again. Now the weirdest is that EVEY TIME this happens, my power locks stop working, so I have to disconnect the battery for a few minutes and everything works back to normal again.... any advise? It would be GREATLY APPRECIATED!!!!
Scan all modules for codes
Where are you located I j have a truck with the same problem
I'm not much of a fan of GM anymore. The fact they can't maintain their websites to work with common browsers is pretty lame. Let alone $40 to get the data to program the expensive part you just bought from them.
$40 is a drop in the bucket. A little annoying to have to update my programming computer every time I need to program a GM though (not very often). Process is super simple once updated though.
But it's cheaper than taking it to the dealer, who would have also recommended the replacement of all the other modules, as well as the steering wheel, steering column, steering box, tie rods, idler arm, steering knuckles, and the entire engine and transmission assembly, just to be on the safe side.
the chevy i did i did with my launch and it came from dealer
