    LMAO you woke the Gremlin, you may have blown the fuse with that connector you unplugged

  2. Avataaar/Circle Created with python_avatars Arthur Newman says:

    Temps have been swinging all over lately. Way way way back when they first come out with the electric actuators. Some time with very cold or low diff fluid it the servo wouldn't shift the and lock into 4×4. Just thinking 🤔

  3. Avataaar/Circle Created with python_avatars Nick H says:

    Tool it in right after warranty expired and sold it back to dealer cause it had a bunch of crap wrong with it and still owed on it and not even 2 years into owning it it was turn ik ng into a turd …..but right b4 I gave it back to them the fro t half axles were garbage anyways so did a bunch of 4×4 drop the clutch donuts shit that was fun store up that poor mcdonalds parking lot…..lol

    Only brand new truck I've ever had! Miss my 05 colorado it was regular cab regular bed z71 off road 4×4 5speed with the mighty 2.8 4cyl chineesium knock off of the toyota 2.7 sounded just like a yoga and basically was a Tacoma and that's why I got it I wanted a yoga but the Colorado was like 8 grand cheaper was a bad arse little pick em up truck but push button 4×4 sucked and wasnt great off road and didnt ha e enough GVW to pull anyone out of the ditch cause it was a chinesium tonka truck toy…..

  5. Avataaar/Circle Created with python_avatars Kyle S says:

    I wonder if the blown fuse was due to disconnecting 3 grounds without disconnecting battery power.

  6. Avataaar/Circle Created with python_avatars Gary Meredith says:

    Mr O I am totally confused I watched this video two times whenever you test something you are the most thorough mechanic out there and I cannot figure why this Colorado is now working correctly when you didn't work on the wiring all you did was some programming I mean there are no rusties no crusties no green junk on the terminals what is that the only problem that was wrong with this truck I am lost on how you got this thing working can you please explain .

  7. Avataaar/Circle Created with python_avatars Welding Junkie says:

    Good thing it wasn’t A, B , C & S 😂 my wife has Invisalign I feel ya. Not fun to be like that.

  8. Avataaar/Circle Created with python_avatars Captain Butt nuggets says:

    I wish i had half of your knowledge and patience, I can’t wait for the day that I don’t have to fix anymore vehicles 😅and helping my company get richer

  9. Avataaar/Circle Created with python_avatars mccalejk says:

    The biggest clue it’s a scam is the person’s accent. Are we so PC these days that we can’t say this? 99% of scammers are African or Indian.

  10. Avataaar/Circle Created with python_avatars HUCKLEBERRY says:

    POS Chevy, always good for repair shop income.

  11. Avataaar/Circle Created with python_avatars ` says:

    I can't go through all 750 comments but did he eventually see the atc motor needed the engine on for that test? even if its n/a

  12. Avataaar/Circle Created with python_avatars moklock says:

    The electricals on those are so bad. Janky cheap ground splices under the hood cause so many weird problems

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

    it's all fun and games until the logic becomes illogical. 🥳

  14. Avataaar/Circle Created with python_avatars Baz W says:

    My guess is they unplugged the transfer case connector looking for a power when they were fitting that GPS 😏 they're too close together to me…. But what a pain, hopefully they'll book it in for a full service and O2 soon 👌

  15. Avataaar/Circle Created with python_avatars Victor Ringe says:

    Ignore your teeth and they will go away.

  16. Avataaar/Circle Created with python_avatars PelkBuilt says:

    Merry Christmas from New Hampshire

  17. Avataaar/Circle Created with python_avatars Someoldguy says:

    On my truck like that the dash readouts/lights don't always work. Also my back-up lights don't want to stay working. I still really like my truck. 219,000+ miles on it.

  18. Avataaar/Circle Created with python_avatars Ty Matt says:

    You fixed it by reseating the module connector.

  19. Avataaar/Circle Created with python_avatars David Sparks says:

    BAD GROUNDS CAN DRIVE ONE N U T Z !!! ELECTRONS MUST HAVE AN END TO FLOW…HUGE CIRCLE ON A VEHICLE!!! I SAW YOUR FIX ON THE TRUCK WITH THAT GROUND GOING TO FRAME…HOOORAHHHH!!!

  20. Avataaar/Circle Created with python_avatars mark gentry says:

    It's a chevy from Mexico

  21. Avataaar/Circle Created with python_avatars Brion Greco says:

    Is it 3.5 or 3.7?

  22. Avataaar/Circle Created with python_avatars Bryan Phipps says:

    Looser connection that got touched, then fixed.

  23. Avataaar/Circle Created with python_avatars Charles Reiche says:

    This would have made a great Halloween special, spooky truck.

  24. Avataaar/Circle Created with python_avatars Luis Marty says:

    Merry Christmas to you and your family, Eric.

  25. Avataaar/Circle Created with python_avatars klystron says:

    As honest as you are, the customer got his monies worth.

  26. Avataaar/Circle Created with python_avatars oldfarmer says:

    Oh the teeth thing. I know so well, the older you get the more has to be done and the more money it takes. You would think in this day and time with all the advances in just about everything known to man there would be something invented, discovered that we wouldn’t have any problems with our teeth. But then I guess that would put a lot of dentists on the unemployment line. Kinda like cars if they were built worth a crap Mr and Mrs O would be doing a cooking and farming show.

  27. Avataaar/Circle Created with python_avatars 73 Maverick says:

    The problem is it is partly an Isuzu I series. I can't stand this series trucks.

  28. Avataaar/Circle Created with python_avatars Michigan Adventure Boot Camp says:

    So, am I the only one that hits the mouse scroll to read ahead. But only scroll the video off screen to the comments. Or the classic, move your head to get a better look at what Eric is trying to show.

  29. Avataaar/Circle Created with python_avatars Wind Ward says:

    The code sequence 2H-N-4H-4L, as per your sheet, has three encoder signals changing state and one not changing state. However, I think there must be intermediate states, not listed on your paper print out to give the motor better positional resolution. My guess would be P is used for end positions, and ABC used for intermediate absolute position represented as a Gray Code sequence.

    When in doubt for an intermittent which will not repeat is clean connector contacts. Spray the contacts with Deoxit D5, cycle (connect/disconnect/connect) the connector a few times and this will, in my experience, rule out a faulty pin connection. Then as you have done inspect potential problem areas like chassis grounds.

    So, are we still quitting?

  31. Avataaar/Circle Created with python_avatars Gary Mallard says:

    YOU sound SILLY….😉

  32. Avataaar/Circle Created with python_avatars 716 auto says:

    😂😂 it always happens when you want to go home

  33. Avataaar/Circle Created with python_avatars Larry Morgan says:

    Hey Eric, love your videos – I've learned a ton! Curious about your Tech 2 scanner setup and what hardware you use with it? Looks like it's wireless, which would be handy. I know you're a busy man and probably won't find this but if you do and have a minute please go over what you were using in this video. Thanks and Merry Christmas!

  34. Avataaar/Circle Created with python_avatars DjResR says:

    Sometimes disconnecting and reconnecting works wonders._

  35. Avataaar/Circle Created with python_avatars Mark Petrassi says:

    It's called pulling my hair out problems

  36. Avataaar/Circle Created with python_avatars Old Mercedes s/w 124, and almost of grid living says:

    Eric , do you miss that time when cars didnt have "brains" to complain every little hickup in it, and turn funcktions down, what ever driver cant do?? ECU I can understand, but everything? like washerfluid, oil level, tirepressure, those basic things driver should to to, even check if any lightbulp is working, and sometimes is there fuel in tank, when its no run, just cranking.

  37. Avataaar/Circle Created with python_avatars James Martinez says:

    IDK, seems like when a customer adds AM electronics components, in this case the GPS tracker, if not properly installed can lead to miscommunications, in a 94 Honda Accord I had, the previous owner added an alarm system. Began to get service light warnings, stuttering, stalling, sometimes would turn off without warning, sometimes D4 light would go on. Finally disconnected the alarm out of frustration and lo and behold, the car worked great and lasted another 100k without major repairs. Just throwing my thoughts out there

  38. Avataaar/Circle Created with python_avatars Glenn Bokma says:

    Hello Eric, great videos. What do you think of this scan tool I am interested in? 2022 New LAUNCH X431 CRP123 OBD2 Diagnostic Scanner ABS SRS Fault Code Reader..

  39. Avataaar/Circle Created with python_avatars avid dyi'er says:

    I particularly love these types of videos. It shows real life. As a DIY, when stuff like this happens to me, I feel like I'm missing something, probably something stupid. Or it's just me. Comforting to know that it isn't always me. 😁

  40. Avataaar/Circle Created with python_avatars Clovis NeoCoCo says:

    I Subbed a while ago and your content created has really improved.

  41. Avataaar/Circle Created with python_avatars Gary says:

    Sometimes you just got to walk away and come back later good to see that we are not the only one that gets pissed off 😄

  42. Avataaar/Circle Created with python_avatars James Dvorak says:

    You've never made a stupid video. Thanks for another good one; looking forward to the next!

  43. Avataaar/Circle Created with python_avatars Kevin Payne says:

    I would bet that the connector by the battery was disconnected, temporarily when they did the aftermarket install. And the code was never cleared after it was set. And the service data does read, "Once the code is set, it will remain set and only allow 2WD."

  44. Avataaar/Circle Created with python_avatars John Petersen says:

    I loved when you said "well we fixed it till it was broke" . Doing the right thing ain't always easy, is it!
    Clarity in this one on avoiding wild goose chases and sticking to the data is great advice.
    Thanks for another good one!

  45. Avataaar/Circle Created with python_avatars K Kampy says:

    We call this fixing it to death.

  46. Avataaar/Circle Created with python_avatars joeyf504327 says:

    That aftermarket device had PWR, GPS< and CEL indicators. The CEL indicator was blinking. Is it an inhibitor?

  47. Avataaar/Circle Created with python_avatars Ray Demos says:

    Eric you sound just like Cindy brady from the Brady bunch with your S is

  48. Avataaar/Circle Created with python_avatars Chris Corts says:

    NOT a stupid video. This is the real life of an auto tech, right down to dropping a fuse into the abyss.
