ABS Light and Traction Control Off Indicator - 2004 Chevy Implala

- In this video, we resolve the ABS and traction control problems on a 2004 Chevy Impala. The wiring problem found on this car is a very common problem on Chevrolets from around this time period. Always troubleshoot, don't just start swapping parts. It can potentially save you a lot of time, money, and unnecessary effort. When you see the part where I take apart the ABS computer plug, just ignore it. It is too tricky and unnecessary. The wire appears to fail further down in the wiring harness. From what I saw of the fasteners in the computer plug, there is just too much risk of messing it up permanently.

Hello again Trey. I traced out the wires for the right side and found a broken on in the loom under where the axle is. Once I repaired that I was able to ohm out the pins, which are pins 4 & 5 for the passenger side along with pins 2 & 3 that you mention in your video for the driver side. I thought I'd update you and others in the future who read this along with thanking you once again since you allowed me the ability to feel confident enough to pursue this issue. Have a blessed day.
Not sure if you guys gives a shit but if you're bored like me during the covid times you can watch pretty much all of the latest series on instaflixxer. I've been streaming with my brother for the last days xD
@Jonas Jefferson yea, I've been watching on instaflixxer for since december myself :)
@Jonas Jefferson yup, I've been watching on instaflixxer for months myself =)
Good video, I have fixed many ABS issues in the last 4 years and you tested wires that many do not and suspect the hub and just do swaptronics only to figure out that they wasted their money. I like how you tested the in between wire as this has resistance also. I fixed a Sienna this way as the sensor was good but wire was Out of Limit. bought a replacement for $20 at a junk yard as I pulled it myself and tested it before buying.
Thank you. One of the best video for this. I have 2002 Monte Carlo SS with rear harness issue. Joy on bliss! I think the wye harness joins up in the trunk. I'll start there.
Wanted to thank you for such a detailed and easy step by step video. With your instruction, I diagnosed and repaired my issue on my 2004 Impala. It was identical to your problem. Thank you again!
I have had problems with this for years. I have change hub bearing and no results. I just saw this video and pulled the ABS connection apart blew in it and plug it back in then started my car. The damn light went out! Wow!!! I restarted the car about 10 times and drove around in disbelief. Thanks!!!
I'm wondering if the sensor being dirty or corroded is the problem with my car. Never a problem until I had to drive it through shitty winter weather here, inches of snow on top of ice and all the ice, snow, gravel, and salt on the highways.
Yeah I watched a guy simply unplug and plug back in harness by tire rod on drivers side... fixed it in about a minute lol
Great help Trey! I tested resistance as you instructed, and replaced the sensor harness for $38.00. Everything works fine now, saved me lots of money and headache! Thumbs up and many thanks!
Very glad the video was useful!
Great video, I liked how you showed and explained what you were looking at and doing. Thank you
Very well done, I have the exact same problem and will go ahead and trouble shoot the connectors, takes much for sharing.
Good job of explaining this repair in great detail.
Thanks! Very well done informative video. This will give me a jump start on diagnosing the problem with daughter car.
Thanks for all the homework you did for me, I found out that I had a problem with a broken wire in the passenger side wire harness and did a splice with two barrel crimps, heat shrink and some plastic wire casing. works great with no lights. Again thanks much !
Tom McDonald what size /gauge wire did you use? Thanks
Duane St John
Duane, I bought a ten dollar harness on ebay and it was about 5 feet long with the plug already on it and it was a 16 or 18 gauge wire I believe.
Thank you, I have the same problem and I'm going to check to see if I have the same issue.
Thanks so much for the info as I need to do this on my 2002 buick century, will let you know how it goes.
This is the best video for this problem
Had this issue several times on my 2004 Impala. Turned out once to be corroded connections inside the bearing harness. Second time it turned out to be a pinched bearing wire - the strands were slowly breaking one by one. It would set off the three lights (ABS, Brake and warning centre) when you were turning.... when you hit bumps... heck even at a stop and when you hit the accelerator. Odds are - if you have the three lights come on erratically - backing out of a driveway and coming on when you turn and pass over the curb... or driving along and coming on when you hit bumps... or turn the wheel sharply... its a WIRING issue. Somewhere, either the wiring is shorting out - as you saw here - or its not making a good connection. GM's harnesses are notorious for letting water / salt in through the top and corroding inside. Check these first before some mechanic says - oh, its the bearing... cause these are expensive. and a pain to change if they are seized. And the ABS control module doesn't go that often... I go through wrecking yards all the time looking for shiny new parts and NEVER see shiny new ABS control modules. So don't let some scammer mechanic say its one of those until you check all the harnesses, the wiring, and the bearings. And bearings more often fail on the passenger side... since the tires on the passenger side fall off the pavement and hit the shoulders and ruts there more often than the drivers side tires do... I have many miles on the Impalas I've owned so learned the hard way. Hope this helps someone.
Ranger Rick thanks man your comment somewhat helps me seems like you know what you’re talking about I need help. Just yesterday I noticed the” trac off “ light and “ABS” light were on and also the “Service Traction System” light. Don’t wanna take it to a mechanic because I feel they will try to scam me. Idk what to do
Im having same issue on 03 impala. All 3 lights coming on. Damn thing scared the crap out of me one time, went to stop at a intersection and brakes felt like they werent going to stop. Felt a crunchy/grinding(like it was trying to engage or something)feeling in brake pedal and thats when the damn trac control lights came on. Slowly been getting worse. Now lights come on just backing out of garage, or slightly turning wheel.
Thank you so much because of your video i can now avoid a costly shop repair. Turns out my wire was completely disconnected from the hub sensor. again thank you :)
funny thing I checked with my meter on both rear hubs and the harness and got the same readings , but when I swapped sides with the harness it always says the right rear sensor in the codes , even after clearing the codes with my autel maxidiag, but it won't clear the right rear sensor at all
thanks for helping at 4:00 min in i looked and just needed to push plugs together
cody Nothanks I wish I was as smart as you!! After reading your comment I looked down at the wire and noticed it was squished between the AC lines and had been worn through!!
41 ohms sound right on my right wheel wire plug?
I have a 2003 impala ls 3.8 w the same problem, I also noticed your Rpms run about 700? So do mine is there a specific reason for that?
Thank you for a good video !!
Just came across this video and our 04 Impala has the same lights showing on the dash but when the car initially begins moving like coming out of a driveway it makes a devil of a grinding noise, could this repair possibly take care of the issue? Thanks for any help. Bob
I know this is an old video but I had the exact same problem. Watched this decided to go down to the driver wheel disconnected the plug from the sensor unclipped the harness about three clips back to give me room to work. Then peeled back the harness cover found the yellow wire was broke bout 6 inches back from the plug. Patched it with a wire connector the electrical tape it for protection the placed the harness sleeve back on. Plugged it in and no more error. Hope this helps someone.
I think that's the best way to go you don't need those stupid sensors on the front wheels anyways old cars you never had them and you don't need them on the new ones
Would that be related to why on my Monte Carlo, same as Impala, has the BRAKE light on in cluster? But E brake is fine, so idk..
@@freddygranado3217 These cars aren't so new anymore ;)
Have a had that problem when turning since I bought the car 4 years ago. It engages the traction control and has almost got me in a wreck several times. It dosent happen all the time either.
Awesome, mine does make the noise at low speeds while turning. So I’ll definitely get that checked. Thank you so much.
Did you figure out what the problem was?. I have the same problem
Great job! Now, I would have taken the ohmmeter to the old wires and checked the resistance once again to show that the wire itself, and which one was broken causing the high resistance reading.....
what color is the signal wire in the back?
Tank you for details
Thanks for the video. Today I began to have the same issue with my 2005 Impala, and the little bit of online research that I've done so far indicates that the problem is difficult and expensive to diagnose and repair properly. I'll stop at AutoZone tomorrow for an ABS code reading to see if I can get a good starting point to proceed from. My problem is identical to that of others that I read about, the brakes pushing back the first time that I apply the brakes at slow speed after having been parked in a lot, then the ABS and Traction Control Off indicator and warning lights coming on, then the warning light soon turns off but the ABS and TRAC lights remain on. But fortunately (so far) the brakes perform normally while driving at normal speed. The problem occurred this morning moments after I stopped to check and add air to my tires to bring them up to 32 psi cold, so now I'm wondering if the tire pressure sensor system is in any way related. WTF, what can go wrong with a simple electrical wire between one end and the other barring a traumatic physical injury to the wire? Is it defective copper stranding or molecular problem with the copper? A wire cannot oxidize if it's properly insulated from exposure to air. Godammit, the more sophisticated that these cars' sensor systems are made, the more trouble we always have because the warning systems themselves go bad. (I'm also dealing with an airbag warning light that I had ever since I bought the car used.) But in any event, there's no way that I can spend $1,500 or more on this car to repair this. For one thing, the +/-20 MPG that I'm getting sucks, and I need to have a complete diagnosis done because beyond that, the car runs great.
The one thing that I'd try first if the sensors or wiring harness are suspect is contact cleaner on the plug connectors to clean any oxidation or dirt, and then proceed from there. The worst case scenario is a bad control module or worse, a bad pump. Mama said there'd be days like this. Thanks again.
I had the same problem the same code and I watch this video and then exactly what you did I checked it found a broken wire about 8 inches from the plug to the ABS sensor I offset cut the wires the top and bottom the new wires through there and have them twisted I solder them and cover them with heat shrink and it only lasted one day and the same codes back what's wrong I have four brand new wheel hubs I am very confused is this situation
Love your very helpful video. Can't wait to check mine out. Can you buy twisted wire somewhere or do you just make it?
Bart Jones I just made the twisted pair with 2 wires. If you clamp two ends in a vise or get someone to hold them and then chuck the other two ends into a drill, and you're off!
BBB Industries offers free access to the Technical Service Bulletins (TSBs) issued by GM and other manufacturers. This is a treasure trove of information on known problems with GM and other vehicles. For example, my 2010 Equinox has similar issues, and in looking at the TSBs for my specific vehicle I noticed PIT5062C (the problem with the 2010 is not mentioned in PIT5062 A or B), which describes a bad splice in the wiring harness under the carpet just in front of the drivers seat, as well as a large plug that gets loose from the connector and lets the pins corrode. The plug and connector are located ahead of the front passenger seat and mounted in a high position sort of behind the outside kick panel. That TSB has pictures, but the complete TSB with the pictures is not easy to find. Alldata and Mitchell don't have this TSB at all, as far as I can determine after searching both of them. This is just a small example of what you can find if you dig deep enough. The dealers will never mention these easy fixes. Another source of inspiration is a TH-cam video by Tony Lester, who dug deep on his own and found a really bad ground on his 2014 GM truck located just under the bottom left corner of the inside of his windshield under a dashboard panel. Misapplied insulation kept the "grounded" wires on his truck from making good ground contact, causing all sorts of electrical issues.
I can't see where you have the red jumper wire connected under the hood. Anyone?
Hi there & great video, I have read many others about the Traction Control service light & ABS light coming on but I haven’t read any with it making a loud noise while the lights are on. When they go off the sound stops. I have an 02 Impala so is my issue completely different because of the loud sound I hear when the light indicators come on?
I can't say, but this vehicle did make noise when turning at low speed. I would suggest checking the abs outputs to see what it looks like.
Mine made a load noise when I accelerated like a grinding noise but I think it was just the brakes reacting to the perceived slipping of the wheel. That is also when the traction control light would light up like the wheel was slipping. The wheel was not slipping. Mine was a faulty wiring harness on the left front wheel. After inspecting the wires I found a discoloration on the wire, sure enough when I pulled the wire it came apart. spliced in a new abs wiring harness and now it is running like it should no more alarms no more noise. I like my impala again.
Mine does the exact same grinding and lights go off after the grinding stops mines a 2013
Could this issue be effecting my transmission at all?
Does it cook popcorn?
There is actually a bulletin out there for these. No. 03-05-25-008. Not certain if it covers the 04 Impala though. I have also seen this on Cadillac Devilles. You can get the jumper harness although it is a little pricey. I have seen this happen where they break down between the main harness it goes into and the wheel speed sensor connector.
15 bucks on amazon for the harness
Nice very helpful
Also have heard that on the 2006-2014 series its not uncommon for the wires to get in contact with the chassis and rub it and short out.
Tumbleweeds can cause this issue as well, I was driving thru Kansas a few weeks ago and you could not help but run over the tumbleweeds they were everywhere. That is when my problem started. Dang old tumbleweeds one must of got caught up in the wires and caused my damage. All fixed now, just spliced in a new abs wiring harness. No more alarms. Maybe I need a cow catcher for tumbleweeds on my impala.
Hello Trey. Thank you for the awesome video. You mentioned pins 2 & 3 for the driver sensor. What are the pins for the passenger side please? My open is on that side. Thanks again.
Impala Lover I'm not real sure which pins that it. You might search for a schematic or physically trace the wires. That's what I had to do.
Okay. I appreciate it. Thanks again. You really helped me out a ton. Thanks for taking the time to make this video.
I have a 2005 my light came on and it said to service Trac control took it to a shop they replaced both axles and both front wheel bearings but the light is still on. I don't want to pay anything more until I find out what it could be from !! PLEASE HELP ME!!
Great information video sir.. Was just wondering what size or gauge wire should someone use? Thanks a million...
18ga should be fine. (18 gauge)
More important than the gauge (size), is its flexibility. Both of my cables in the front had broken the wires internally due to the minute, but continuous flexing while driving. They were broken where the bottom of the suspension meets the frame (not too far from the connector IIRC). You wouldn't think that it would break there, but it did.
The way that you find a broken wire is to look around where the cable flexes for a bulge in the wire. Grab the wire from either side and pull. If it's broken, the wire will continue to stretch until the insulation breaks. This is what I found on three of the four wires on my Impala.
The factory harness was about $150 (per side) from my dealer, and it was not likely to last any longer than the original. So I replaced mine with "Olflex" superflex cable (10 million cycle rated) that I got off of eBay for about $40 (I only needed a foot for the entire job, but this was the best deal that I could find at the time). Flexlife-10 is another option. We use this type of cable in our robot cells where we may build 250,000 parts per year.
A better option is to buy a 3 foot chunk of 18 gauge "Superflex 2" from TQWire for $3.50. Use marine-rated butt splices (shrink tube ends) to keep the water out. Since this is an individual wire, and not a multi-conductor cable, you will have to use one wire per conductor (you will want to replace both conductors per side). The TQWire wire is a better wire than the Olflex (441 strands, quite a bit higher than the Olflex IIRC), and being an individual wire as opposed to being part of a cable is of no consequence.
Thank You pretty helfull
Thank you
Does this work with 01 Pontiac grand prix as well? If so please comment asa0
emovampylady 1 it is the same its the same car different body
I just had to have mine fixed and it was the Hub it was broken. Had it replaced last week and the indicator is off and when I press the Traction button on the left of the steering wheel it works. Before it didn't. it was on the Right front tire.
Dorothy Owens - Good deal! I'm glad you got it worked out!
I have a 03 impala ls, and my dad told me to just turn the car off and back on, and it should fix it. He said those impala's have glitches in the computer system.
Hes right I turn my car of and back on again and it stops
thanks
Anybody have any idea if this is the same on a 2000 Impala LS ?
Yes 00-05
@@malcomspicer3026 I went to check mine and found my CV boot was bad by the time I got it replaced I was done ... I haven't even got back to check it again
What patients, good troubleshooting have to be an ex Local 3 electrician...lol
cleaner the ground connector ABS down of the car in the drave side has roost oxide . cleaner with sandpaper .
Thank you for this info
both lights are on in my 03 when I brake from speed the back wheels feels like its shaking what does that mean
I got the 1218 code for ABS
See now my issue is different.. 03LS 3.8 with the traction warning, brake warning and the low brake fluid warning (fluid is full) everywhere I've brought the car I never get a straight answer
0Sideswipe0 Hate to hear that. Would be an interesting diagnosis if you were closer.
Trey Clanton yeah.. I'm in ri not sure where you are
is a wire of ground .
Lost me at electrical
Here were are again

I fixed my Chevy Impala problems by getting a Honda Accord lol 😂
