In this video I have a look at a 2005 Jeep Grand Cherokee That came in with the dash lit up! ABS, Trac, Engine light etc. I find out pretty quick it has a no communication with the ABS module. Let's see what we find. -Enjoy!

    Perfect Video to teach troubleshooting WK electric gremlins. Once the signals get into the BUS they get lost is space. Eric's testing the connector for power and ground and working bus was exactly the right way to find the problem. Now to find a cheap DIY scope to verify the two Canbus wires.

    Thank You for your help and inspiration. If you weren't 500 miles away would be at your shop in the morning!

    After multi high priced scan tools were used (many dollars), I found a bad ABS module on my '98 Dodge. My opinion is ABS is useless.

  3. Avataaar/Circle Created with python_avatars G R says:

    Hello love ur videos. Quick question, on a chrysler 300 c 2006. Abs module wiring harness, coming out of the module towards the vehicle there is a black cable that is cut. I have looked everywhere for the other side of the cable and wiring diagrams dont show a black cable. I have the abs bas light on. Please help.

  4. Avataaar/Circle Created with python_avatars revscott58 says:

    Does anybody know if any testing of the ABS module can be done on its pins with a multimeter? Or would the ohm settings voltage in some way do damage to the module? I also wonder if the same codes could be coming from FCM, or PCM? Blessings.

    nice video, very helpful

  6. Avataaar/Circle Created with python_avatars Greg Hofacre says:

    Thanks for the great video. it helped me diagnosis my caravan with the same Teves ate mk 20 module. Sent module to Module Masters for repair. Abs works great after the repair. Used foxwell nt630 elite for diagnosis.

    What scan tool are you using? The green one.

    Hi dear, I have 05 jeep grand Cherokee hemi 5.7L, and the error code c1243 and dash light is on all the time and shown in the system G sensor is not working, I change it but same no improvement at all, please advice.

  9. Avataaar/Circle Created with python_avatars Adan Lopez says:

    I'm curious too say, u made the call on the abs mod, question is would you still comdem abs mod if it was showing erratic voltages on the network when plugged in? In the vid You would think the mod its fine since it didn't do that or drop the network. Love the content by the way

    Got a 2008 2500 recently I lost my abs system uo121 and p0501 … This has shut off my exhaust brake and all and related like speedometer. I don't see any bad wiring at the sensors. One thing I found that started at the same time is the reverse lights stopped working and I noticed they work..key off…when in reverse but there's no power key off . I will need to check my abs module for power and ground and power key on …but like I said I know reverse is showing no power key on but has key off power . Would there be a possible ignition switch wire issue to look for ?

    Muy interesante. Amigo espero un día ser igual qomue tu en mecánica

  15. Avataaar/Circle Created with python_avatars Generic Username says:

    Is there a way to diagnose if CAN signals are working if you don't have a scope like that? Any way to do it with a DVOM or test light ?

    Very informative to watch!

  20. Avataaar/Circle Created with python_avatars Christopher Barnes says:

    I have noticed that you switch between a regular test light and your home made test light with the larger brighter bulb i assume the home made light loads the circuit can you help me to understand when testing circuits when to select the home made style or the regular style light?

  21. Avataaar/Circle Created with python_avatars throttle bottle says:

    lol, maybe they spliced the front wheel speed sensors together to fool the thing and not replace one or some chinesium alarm/immobilizer/logging or vehicle motion pickup?
    nothing surprises me anymore at finding stupendous things

  22. Avataaar/Circle Created with python_avatars throttle bottle says:

    it's a jeep, the whole thing needs to go missing……………

  23. Avataaar/Circle Created with python_avatars Curtis Roberts says:

    The scope is such a beautiful tool for these types of diags.  I got my MicSig (just a starter for now; it's what I could afford!) about six months ago and in no small thanks to you I'm leaning a lot more of how to use it.  Found a blower motor that would intermittently speed up when hitting bumps in a Cheevy with only 34k miles.  Without the amp clamp to catch the power spike and the psm signal being measured to prove it was internal to the motor not the control module it would have taken a lot of work to try and find a short or some other issue.  With the scope I had proof and it did solve the problem and proved the new one no longer spiked.  Not only was it easy but ensures warranty pays and we don't get a charge back!  Same with a cam actuator solenoid.  Signal is good and solenoid it outside the range.  No circuit tests needed.  The digital visual proof that comm is there while the malfunction is there eliminates a tedious GM procedure on testing the part and circuits.  What i'm trying to say is thanks for being a great teacher and skilled mentor big guy!

  24. Avataaar/Circle Created with python_avatars Pete Medina says:

    Cool diagnosis look forward to a part 2 hopefully.

  25. Avataaar/Circle Created with python_avatars Adrian Martinez says:

    Just a thought. Wouldn't it be interesting if when ever you did a segment on a particular brand of vehicle you also wore a hat with that brand name, such as a Chevy hat for a Chevy, Ford for a Ford and so on. All just for play that is.

    What ever happen to your Jeep? Is it done for also?

  34. Avataaar/Circle Created with python_avatars Jared Brooks says:

    I am confused, if there is no comms problem, wouldn't the can signal be skewed ?

    GREAT DIAGNOSIS WOULD LOVE TO SEE PART TWO…, IF POSSIBLE THE PROGRAMMING DONE WITH AN AFTERMARKET SCANNER NOW THAT WOULD BE SOMETHING VERY NEW . MAYBE WITH ONE OF THE LAUNCH X431 SCANNERS OR JUST AN AFTERMARKET ONE BECAUSE YOU DO HAVE THE KNOW HOW AND THE EQUIPMENT AND ONE OF THEM SHOULD HAVE THE CAPABILITY . ALWAYS ENJOY LEARNING SOMETHING NEW ON YOUR CHANNEL THANKS YOU FOR YOUR TIME ! ! ! JUST CURIOUS IS ALL WELL WITH KEITH DEFAZIO JUST ASKING BECAUSE HAVEN'T SEEN MUCH FROM HIM LATELY THANKS AGAIN ?

  46. Avataaar/Circle Created with python_avatars Jason Michaels says:

    Why was the sensor lead tapped into anyway?

  47. Avataaar/Circle Created with python_avatars jon gone gone says:

    uh oh, back to the wiring, no extra fuses needed.
