In this video we have a look at a 2005 Dodge Neon that was towed in from another shop with the symptoms of a no crank, no start. It didn't take long to find out that we could not communicate to the PCM. After a quick look at the PCI Bus we find the problem. -Enjoy!

    Hey it's really people like you and other people who help out people, for me very thankful. So I was going down the lit with you. This just happened to me today. I was trying to help my soon to be ex wife and figure out hear heating issues. We just got done replacing most of all air and intake plus Radiator, Thermostat. The thermostat worked but quite in less than a month. 2003 Dodge. Rented a compression kit because after auto Zone got home pooped hood, had radiator fluid coming out of reservoir. Had the tester in #1. Remove fuel fuses, and ignition fuses. UnHooked up battery. Was ready to start went to turn it over an forgot to place battery terminals back on. Turned the key, same garbage. Except parts of the under the hood fuse area had no power, couldn't keep an see where you were placing the wire into the connectors. I don't think I have power in the PMC. I am counting on you to figure this out. It's her daily work and running around weekend thinking she's 20 again. I had to give up after burping the car for a while and taking everything apart for the humpty Time, screw those car's. But I have to get it up working before she comes back Monday. Only if you could. Low compression. All signs I seen was worn out valves. And piston ring. She getting the Thick 4 cylinder Restore. Know much about tranny's. Mine started to hesitate 3-4 sec to 1st , about 2 sec for second. I need to get her car done. So I can get back to redoing my 1984 Honda Gyro 50nn MD. Scooter. Forgot Been replacing things she can afford. Never knew you should put your Brain on a charger to keep it going. Or have the person put it they're scanner gun and reboot the computer for higher charged battery, can do damage. I don't have special tool. She called me earlier, I told her she lost it. I have a black plague when it comes to working on rigs an now scooter. Please help me. Junk yards are closed around here. I'll have to grab anything off possibly eBay. I'm thinking water might have go into the fuze box, I don't have a garage, so had to use my patio umbrella between cars to work. Oh ya. Most of the fuze that box needed places r on one side . Stater relay box area no power.

    Lots of good tips … audio was great but the video was glitchy/pixilated. May be due to video being old or something.

    Thanks for the info.

    " Some ECMs it's just a failure to communicate "
    Cue " civil war " tune.

    Civil War
    Song by Guns N' Roses

    Look at your young men fighting
    Look at your women crying
    Look at your young men dying
    The way they've always done before

    Look at the hate we're breeding
    Look at the fear we're feeding
    Look at the lives we're leading
    The way we've always done before

    My hands are tied
    The billions shift from side to side
    And the wars go on with brainwashed pride
    For the love of God and our human rights
    And all these things are swept aside
    By bloody hands time can't deny
    And are washed away by your genocide
    And history hides the lies of our civil wars

    D'you wear a black armband
    When they shot the man
    Who said "peace could last forever"
    And in my first memories
    They shot Kennedy
    I went numb when I learned to see
    So I never fell for Vietnam
    We got the wall of D.C. to remind us all
    That you can't trust freedom
    When it's not in your hands
    When everybody's fightin'
    For their promised land
    And

    I don't need your civil war
    It feeds the rich while it buries the poor
    Your power hungry sellin' soldiers
    In a human grocery store
    Ain't that fresh
    I don't need your civil war
    Ow, oh no, no, no, no, no

    Look at the shoes you're filling
    Look at the blood we're spilling
    Look at the world we're killing
    The way we've always done before
    Look in the doubt we've wallowed
    Look at the leaders we've followed
    Look at the lies we've swallowed
    And I don't want to hear no more

    My hands are tied
    For all I've seen has changed my mind
    But still the wars go on as the years go by
    With no love of God or human rights
    'Cause all these dreams are swept aside
    By bloody hands of the hypnotized
    Who carry the cross of homicide
    And history bears the scars of our civil wars

    I don't need your civil war
    It feeds the rich while it buries the poor
    Your power hungry sellin' soldiers
    In a human grocery store
    Ain't that fresh
    I don't need your civil war
    No, no, no, no, no, no, no, no, no, no, no, no
    I don't need your civil war
    I don't need your civil war
    Your power hungry sellin' soldiers
    In a human grocery store
    Ain't that fresh
    I don't need your civil war
    No, no, no, no, no, no, no, no, no uh-oh-uh, no uh-oh, uh no
    I don't need one more war

    I don't need one more war
    No, no, no, no uh-oh-uh, no uh-oh, uh no
    Whats civil 'bout war anyway?

    I've had my '05 Neon for 12 1/2 years with no major problems (knock on wood). My parents bought it from Enterprise (yes, it's an ex-rental) in 2007, then signed the title over to me before my father passed away in 2011.

  13. Avataaar/Circle Created with python_avatars Wildturkey10121 says:

    Mr. O, these are the best videos you make, but any of them are good and I enjoy watching them. I really enjoy watching you work through a problem like in this one. I am re-watching this one just because I'm looking at buying an Autel MS906BT to help with my own cars. I've also bought front axles and brakes for the wifes car due to your videos. I plan on making restitution for your time. Thanks for the vids, your skill and time in making the videos!!!

  14. Avataaar/Circle Created with python_avatars Mathew Boyer says:

    Are you using Pro demand to get that module diagram? Could you do a video on how you find some of the common information you use like this diagram? We have pro demand at work and i have tried to play around with it and find some of the stuff you use but came up empty.

  15. Avataaar/Circle Created with python_avatars shakey says:

    Got a family hand me down Neon once. It broke almost every weekend. owned the car less than 6 months.

  16. Avataaar/Circle Created with python_avatars Joe Clark says:

    How would you check to see if the antitheft system is part of the remote keyless entry. It anyone know how to do so please let me know..thank you

  17. Avataaar/Circle Created with python_avatars Michael Spranger says:

    Pcm outages are popular on chrysler vehicles

  18. Avataaar/Circle Created with python_avatars Skoda130 says:

    Where's the follow up?

  19. Avataaar/Circle Created with python_avatars GNX157 says:

    Eric, surprised to see you charging the battery thru both posts.

  20. Avataaar/Circle Created with python_avatars Glen Atchison says:

    When did cars become driving circuit boards???

  21. Avataaar/Circle Created with python_avatars Inspired Mechanics says:

    Awesome video! Just curious… is this a possible product pattern problem for that year make and model? Do the ecm's fail alot on this vehicle? And if so.. why? Thanks for a great video and hope ya see this and respond back Eric. Have an awesome week! Later gater!馃槅

  22. Avataaar/Circle Created with python_avatars JanitorJay says:

    You should look in to getting matte screen protectors for your tools. Would not only protect the screen from scratches and oil, but also eliminate glare while making videos.

  23. Avataaar/Circle Created with python_avatars John Byrne says:

    Now you know how Chevy Chase felt, checking all those christmas light bulbs!

  24. Avataaar/Circle Created with python_avatars A LeBlanc says:

    I think at least half of your work "comes from another shop." Short of trying to hire you directly, it's still the best compliment a man can get. Thanks Eric!!

  25. Avataaar/Circle Created with python_avatars E Kop says:

    HAD 97 NEON
    NOTHING BUT LEAKS BREAKDOWNS
    GLAD I JUNKED IT AFTER 20 YRS
    ONLY HAD 167K ON IT WHEN I PARTED IT

  26. Avataaar/Circle Created with python_avatars Jason The Municipal Mechanic says:

    You should get sma compressor stickers

  27. Avataaar/Circle Created with python_avatars Antonio Claudio Michael says:

    Great video Eric O

  28. Avataaar/Circle Created with python_avatars Antonio Claudio Michael says:

    Looks like a bad ecm

  29. Avataaar/Circle Created with python_avatars Aaron Loggan says:

    Now I talk like you when I'm working on my car… I'm not complaining!

  30. Avataaar/Circle Created with python_avatars Dag-Erling Sm酶rgrav says:

    What does your shirt say?

  31. Avataaar/Circle Created with python_avatars zoidberg444 says:

    Holy shit Eric. 200K subs? Shit i remember when i was your 3000th odd subscriber. hahaha.

    Great diagnosis, even if i am allergic to Chrysler! Catching up on the weeks SMA videos tonight.

  32. Avataaar/Circle Created with python_avatars J U says:

    I've always said Neons were disposable cars. Dirt cheap and built the same way. Drive it till it breaks, junk it, and buy another one.

  33. Avataaar/Circle Created with python_avatars old-school says:

    vantage pro fixed ?

  34. Avataaar/Circle Created with python_avatars Kevin Morrissey says:

    Drain the capacitor for 4hrs+ by unhooking the battery cables and ziptie them together..

  35. Avataaar/Circle Created with python_avatars Mr B says:

    got your vantage pro back booting then ….
    diag wouldn't be the same without it .

  36. Avataaar/Circle Created with python_avatars Douglas Gagnon says:

    Great videos, I see you are using an autel scan tool on many of your videos. What model is it? And is that what you would recommend to me to get. Our shop has a Snap-on modi鈥檚. It showed a wiring diagram is that part of the tool or a separate option/software? Any help appreciated.

  37. Avataaar/Circle Created with python_avatars Lake Nipissing says:

    Interesting… this is a case where the other shop which had the car聽would have "fixed" the car by "throwing" a new computer in it… but after a month – they didn't.

  38. Avataaar/Circle Created with python_avatars dave1135 says:

    I saw the title, and thought, hmm, no crank,no comm…I bet it's a bad TIPM. Lol

  39. Avataaar/Circle Created with python_avatars Scott Yakoubian says:

    Sorry if this is a stupid question, I鈥檓 just a DIY鈥檙. Can the ECM be programmed easily or does it require special equipment? Thanks.

  40. Avataaar/Circle Created with python_avatars PoncianaPat1970 says:

    Nice work Eric.

  41. Avataaar/Circle Created with python_avatars Paul M. says:

    a chrysler/dodge with a bad ecm, imagine that. nice one, thanks

  42. Avataaar/Circle Created with python_avatars DeadKoby says:

    Seems like a fair diagnostic. Searching for answers rather than just "trying this and that"…. Hopefully a GOOD ECM is in the salvage yard for chump change. I hate to spend a fortune on worn cars. Once a car gets to a certain point in its life cycle, I only fix the things that affect safety and reliability…. If it starts, moves, steers, and brakes properly, the rest can just be ignored…. I have a feeling thar car is getting to that phase of life.

  43. Avataaar/Circle Created with python_avatars Shaun O says:

    Just a thought that hit me when you said you weren't sure the 5 Volt reference was supposed to work with the ASD off. The ASD relay聽feeds battery voltage to outputs while the five volt obviously feeds five volts, but feeds that voltage to聽inputs.聽 That five volts would have to be available with key on or the PCM would never see the crank signal it requires to ground the ASD relay in the first place.

  44. Avataaar/Circle Created with python_avatars Bill Maxfield says:

    nice one Eric. Very logical Thank you!

  45. Avataaar/Circle Created with python_avatars Hola! GrumpyGene's World says:

    So I was thinking Yeah I know that's not normal but I was thinking that it's 2018-2019. Why don't all devices that can send and receive data do not or not set up to send the schematics and manual to the user. that would save a ton of time and a ton of extra expense for repair shops not including end users who d.i.y repairs. I get it they want you to bring it back to them So they can gouge your pockets as your only option is to bend over and let them have their way with your wallet or purse if the person does not know better to take it to a quality and reputable 3rd party shop. Maybe I'm retarded thinking this would be somthing they would ever do..

  46. Avataaar/Circle Created with python_avatars Crystal says:

    Nothing better than ice cold beer and an SMA video on a Friday night

  47. Avataaar/Circle Created with python_avatars Richard Gill says:

    Nice job as always

  48. Avataaar/Circle Created with python_avatars Michael O says:

    Eric do you use the 908 to do skim keys in dodge/Chrysler/Jeep?
