Come along with Eric O. at the SMA shop as he has a look at this Jeep Compass with an ABS Light, 4WD light, and Traction Control Light on and a code "C1041 Left Rear Tone Ring Performance" code stored in the ABS Unit. Now mind you this vehicle has a new speed sensor, pads, rotors, calipers and a new wheel bearing all on the left rear. We soon find out that "NEW" does not mean "GOOD" - Enjoy

    I replaced my hub and now traction control lights came on. One step forward. 2 steps back

    I'd travel the 690 miles to have Mr. O look at my vehicle. There is no one where I live that would do the things he (Mr. O) does in his videos near me. NO ONE!!! Even the dealership where I live are under investigation for ripping off consumers by both BBB and the FTC

    Hi Eric,
    I just replace the front drivers side wheel bearing on my 2010 Jeep Patriot 4wd 2.4. I know I broke the little black tab that is connected to the speed sensor and now I get the ABS, Traction control light and the 4wd! light. Is there a way to replace the little black tab that sits against the bearing? Thank you for your videos they are a great help for those of us with no clue… lol

    Nice. I live in Dupont. Dealing with similar issues. Have my 4wd! ABS, and TRACTION CONTROL light on.

    Please put on the seat belt, just to stop the noise on your video from the warning chime. Great work otherwise.

    What is a drag test

    Excellent video. Great troubleshooting skills.

    The best part of these sensors is that they are current based, they alternate between 2 current levels. Since it is 6 and 14 milliamps (for one from a 5th gen Grand Caravan), both of which is <20mA, the current rating of a standard 5mm LED you can literally hook an LED in series with the sensor and watch it alternate between dim and bright as you rotate the wheel.

    So the manufacture records a pulse train on the magnetic strip ring and you read that back like a cassette tape.
    Defect in the magnetic material possibly? Keep other magnetic items like magnetized screwdrivers away from that magnetic strip or you'll cause problems!

    I fixed mine in 10 minutes with PB Blaster

    Its the Relay Box behind the drivers side headlight

    ***I made the mistake of buying a used 2010 Jeep Patriot. Why Chrysler uses such cheap-ass wiring, coupled with some bad engineering is beyond me. I have probably spent 8-10 hours chasing down faulty grounds on this vehicle. That there doesn't sound like much so probably times that by 10 if you want to put it into days wasted…
    ***lol I was unplugging some of the electrical plugs because from time to time that's what you have to do if there's issues with a particular warning light that keeps popping up once the vehicle is started. The n that would fix that issue but then, it would cause another warning light to get triggered. Then it's back to searching out other plugs to unplug-plug back in scenarios..
    ***I ran into the issue of ''Not Starting'' so I traced it down to the ''Relay Box'' which is located down below the left headlamp, next to the left running lights & the inner front left wheel well. Placing that Relay Box there seems suspect in the first place. Why an engineer would do something like this had to be for guaranteed problems that would benefit their Dealership's Repair Facilities… Out of all the areas under the hood of their vehicles, I mean putting the vehicle's main Relays down where they'd be subjected to condensation, salty slush and the worse corrosion you could expect is just mind boggling….
    ***The results of the last time I worked on it & was able to get the ''Battery Warning Light'' to Stop coming on whenever I started the engine, then the ''Front Seat Heater'' stopped working, I fixed it then, the ''SRS Airbag Warning Light'' came on the very next time I started the vehicle. I belong to a couple of Jeep Forums. One is for Jeep Patriot Owners. The Patriot line, just like the Compass line is loaded with issues that all seem to be related to the ''Rustbelt States''. Almost all the folks in the Patriot Forum that are plagued with issues like mine are in those states. The ones with the least amount of issues live in warmer areas of the contus. I know from experience that Chrysler knows all about these issues since they run tests prior to releasing new models. In other words, if an issue goes into the 2nd model year, then Chrysler is aware that it's a combination of poor engineering & low quality parts. It's a shame that Chrysler doesn't seem to care about these flaws caused by engineering designs
    ***This afternoon since it's a sunny day out I'll be changing the cvt filter because there's a whining noise. Then back to getting our ''Everyday Driver Vehicle'' fixed so my Wife can park the ''Spare Family Vehicle'' which is what the Patriot is. Just an emergency vehicle to use. In fact I'm only keeping it for that reason.
    Okay, I am done bitching about our Patriot. Eric, thank you so much for uploading all the repair & diagnostic videos to YouTube. You are helping so many folks out here who probably don't have the finances to just get rid of a vehicle & buy another one/newer/new one to replace it, I'm sure you are well respected by thousands of folks out there. You Rule Eric – South Main Auto Repair. & thanks again…. MD……….

    New means cheaper to manafacture not better quality!

    New does not mean oem.

    Cool how that did work out

    You could put a small screwdriver on the magnet and see if it's magnetic all around.

    Eric do we know each other because I really like females only. Sorry for the confusion.

  21. Avataaar/Circle Created with python_avatars Martin Kucic says:

    Wear your seatbelt or you will be givin a ticket and you will go to seatbelt hell.
    Where they make you play musical chairs with seatbelts.🥵

  22. Avataaar/Circle Created with python_avatars J.O.A.T says:

    Eric, I am older than you. I have been working on vehicles for well over 30 years. All side work. Mainly brakes, exhaust, and I have done motors as well. But watching your videos has inspired me. I have taken things I have learned from videos and am using them in my repairs. I really like the diagnosing part. I have scanners. I have even purchased an oscilloscope so I can pin point the issues in those stubborn wheel bearings. Thank you.

  23. Avataaar/Circle Created with python_avatars YH says:

    "Life doesn't give you seatbelts" ROTFLMAO. Great job Eric.

  24. Avataaar/Circle Created with python_avatars Lyndon Chappell says:

    Fascinating diagnostic.

  25. Avataaar/Circle Created with python_avatars Thomas Devine says:

    Texting and driving reaction time is is the same as drinking and driving. Testing and driving is probably the same. Testing and driving without the seatbelt on puts you at the top of the stupid list, sober and still making stupid decisions.

    just like new cars doesnt always mean good. like tesla and kia all garbage

    Eric, thanks for the video, learn alot from you!!

  29. Avataaar/Circle Created with python_avatars jmccoy85 says:

    Awesome video eric!!! I recently had a 2012 jeep wrangler with a wss circuit fault code pro demand identifix and my snapon solus ultra said i should see a square wave from .8 v 1.6v on the signal wire……wrong!!!! I did some more digging and research and checked our component test feature in our snap on triton scanner and it stated that the abs module is looking at small voltage and amperage changes and then it started to make sense to me. I SWEAR half of my battle doing diagnostics is having correct service info and accurate description and operation info

    awesome video ty 🙂

  32. Avataaar/Circle Created with python_avatars ROBBIE SUN says:

    WOW all that work would cost $500 where i live…all due to poor quality parts when new??

  33. Avataaar/Circle Created with python_avatars Cliff Medina says:

    Hi Eric, I need your expertise….

    I have a 2001 Taurus that I am on my wits end with. The brake pedal sinks to the floor.

    I have replaced the master cylinder twice…Advanced Auto, after market……Still goes to the floor. All the brakes calipers, rotors and brake lines have been replaced!

    No Codes on the ABS. I have a Launch X431 pro Mini Scanner. I have pulled the ABS and tried to clean in Ultra Sonic and blown out. Activated the valve via scanner seems to be alright No Codes for the electronics Module.

    I must of did a full bleed 10 times now….Still goes to the Floor?????????? WTF could be wrong???????

  34. Avataaar/Circle Created with python_avatars Christian Libertarian says:

    Well, I have a 2007 Jeep Compass (same color), similar problem. I am not going to buy a computerized oscilloscope (more expensive than the vehicle is worth). So, looking at the length of your video, I am guessing it will take the stealership an hour to figure out what's wrong, then $500 to fix it. My Compass may be trash.
