SATURN VUE NO CRANK NO COMMUNICATION CASE STUDY
HTML-код
- Опубликовано: 22 апр 2020
- Welcome back to another case study! Today we have a 2008 Saturn Vue with a 2.4 4 cylinder Ecotec engine. The customer complaint is that the vehicle is a no start and that it has no communication with the ecm. Follow along as I take you step by step through the diagnostic and troubleshooting process to fixing this vehicle. Also, some ecu programming stuff!

Much respect to you guys, I'm 75 and remember the days when you
could look down on either side of the engine and see the ground. I watched
your video which was extremely comprehensive, wondered if you can learn all of this by watching an older fellow and so-called on the job training, or is it necessary to
learn much of this at school.
EXCELLENT TROUBLE SHOOTING PROCEDURES, EXCELLENT VIDEO WITHOUT THE LOUD BACKGROUND MUSIC. I AM A RETIRED ELECTRONICS TECH AND THIS IS THE VERY SAME PROCEDURE I WOUKD HAVE USED. YOU ARE A PRO, THANK YOU.
Wow so glade to see a real true thorough honest auto mechanic, can only hope we all find someone like you. Gracias for sharing...
You have a great, informative channel. I really appreciate the step by step explanations of what you're thinking, why you're thinking it. Very logical and easy to follow. Keep up the good work.
FANTASTIC! GLAD TO SEE YOU BACK IN ACTION! Programming was not my strong suit in the past, so I'm learning from you and others.
Had my fingers crossed that the ECU ground pin fitment concern was the issue.
Glad you guys made the accurate call on this one.
Cool diagnostic video - thanks!
Eric thanks for the excellent video. Really glad you have continued with your videos. This was probably the best ECM reprogramming and troubleshooting video I have watched. From reading the schematic to checking the voltages at the ECM to doing the actual programming. Thanks much hope you and family are all well. Artie 🙏❤️
Hey man , awesome video . Only one little thing you always want to check for 5v ref being shorted
Yes! I forgot to add that he had already checked the 5 volt ref.
Exactly what I was goin to say but ya watched before I did... one thing I do is use aes lead kit connect powers grounds data lines from harness to module male pins see if it’s sometfunny like an out put causing issues
@@philh9238 I like that idea! Almost a bench test of the ecm, no? Just powers grounds and comm wires, and try the scan tool again?
Yes
@@ADVANCEDLEVELAUTO please show how to check SDVC wire is damage in Hyundai i20 1.2 2011
Thank you very much! Finally I can get an answer to my prayers.
You are one of very very few that showed how to program an ecm with detail and for that again👍👍👍👍👍👍👍 of course it takes a scanner with the programming tools but knowing how is most important
Thank you Eric. Good job again. Have a blessed and safe week to you and your family. One other check would use scope on the data wires with ECM connector unplugged and KOEO to verify comm is reaching the connector from rest of the network.
So you didn’t check the datalink? You do realize if a datalink wire or terminating resistor is bad it will cause the exact same symptom, right? Just because an ECM is getting power and ground but not talking on the network doesn’t mean the ECM itself is bad. The network it’s talking on may be the issue. I would seriously consider revising this video with this information included. This diagnostic routine has a very high chance of resulting in a misdiagnosis, and a costly one at that.

I agree and the 5 volt refs were not checked for shorts. He got lucky on that one.
Thanks for the video, I just had that same problem this morning. And this video answer lot's of my questions. Keep up the good work!
Good afternoon family. Your guys are the BEST!!!! Thank you for your time and valuable information 💯❤🙏✌👍
Great job, nice to see you back
Love to watch diagnosis and repair. Now I have an idea of what my shop is doing thanks
I have been waiting all days for your new vedio, thanks again its great
You have amazing skills! With my Launch X431 I can write the old VIN number on the new ECM without any online subscriptions or software reflashings
Hi Argeny, I have Launch X431 v+ the new one i think can do that too so we just need to write the old VIN # and the software should be the same this is with GM only or with other maker too do you have any information appreciate any info sharing .cheeeeeers
@@jgeorges3061 you can do it with any car brand
That is my next purchase
I just got the Launch X431. and a 08 Saturn Vue. New to scanners. Any advice on how to really use this scanner ? Also I want to get a second Ignition key but don't want to pay $70. if this Launch can do it. Also I need to relearn the crank and cam sensors and battery registration. It just won't let me do the battery registration. Possibly update the ECM also ?
Thank man you for keep your shop and channel open.
You the man! Great teacher.
You are really good at what you do, nice content.
You have great skills thanks for sharing your diagnosis and knowledge 👍 stay safe
Good diagnose steps Eric , Again , Thanks bro.
Another Excellent video!! A couple of things I'd like to add. If the ground pin is suspect you might have checked if the LOW REFs have ground in them with the computer plugged. If they do then the ECM is receiving a good ground. And while at it, you might want to check the 5V refs too, see if the ECM has at least some power. And if all this fails you might want to power it on a bench and see if there is COM outside of the car. Also an incandescent test light would work better for powers and grounds as it loads the circuit. Maybe with a 1.5 amp incandescent tail light as a test light. I've needlessly purchased ECMs and have been burnt before by power probes. Once I had a bad ground on an installed corroded junkyard engine. Another time I had another bad power due to corroded wires. The probe didn't detect the faulty voltage, but the test light did. Finally, you know what they say about the ECM being the most expensive fuse. You might want to check WHY the ECM was burnt in the first place. I've had to put in ECM after ECM on the same car at my expense, just because something in the car, some sensor or solenoid, was making it burn out again and again. Just some advice for others.
Thanks man, very informative
Thanks Eric for the video Like I always say your thorough Good luck with ur business CHEERS
thanks Eric for sharing these useful informations, 👍👍
Excellent diagnosis plan!
I got the same problem with my 2008 Vue 3.6 V6. This Video is really useful
Nice diagnose !!!. Thanks for the vid.
Great work 💪 powers n grounds 👍 good to see they made the right call. Nothing wrong with asking for a second opinion
Hey guy this was a really good diagnostic video, thanks so much😀
Thanks for sharing Bro👍
Really informative on quick steps of programming an ECM👍
Stay safe Bro❤
Ap kaha se ho Salmanbhai??
You are the man,great video!
Great job again. Love this channel.👍👍
Great job on programming
Excelent , congratulations, good job.
Great Video, lots of knowledge Brother.
Excellent explanation.
Good stuff. Stay safe.
Very good case study! Thanks for that. Putting fuel can be a good idea by the way ^^
La verdad me gusto los pasos que hicieron y como si enfocaron la cámara , y también lo de los diagramas , los felicito me suscribí hay que apoyarlos con eso y los like . Saludos form Fl .
Appreciate the videos
Good Job 👍
Outstanding, no BS.
Bro God bless Your Knowledge! Very good Trouble shooting. Not many people better yet so called mech/Techs with that type of practice.
Good job love it
Awesome diagnosis Eric! Just wanted to point out that at 1 minute you pointed at the CEL but that wasn't it. The CEL is in the lower right corner and never illuminated. Stay safe!
Yes! I just realized that. Thank you!
@@ADVANCEDLEVELAUTO hi Eric I will like to know if you can fix a 2013 BMW it's in Baytown please send me a message to generalsolutions2017@yahoo.com to explain about the problems I have. Thanks
Great catch!
Great case study. Straight to the point and you included the programming procedure for those who might not have done it before or are curious about what it takes. Something I will note, as it has bitten me before - I've been fooled by my Power Probe showing good voltage or ground despite the circuit not being able to carry a load. Once I've verified that powers and grounds are good, I'll unplug the connector(s) and put a load on the circuits (I have a 3157 bulb and pigtail I like to use) just to ensure they can carry the load of the ECM. Thanks for posting your video. I hope you are safe and well, considering the craziness lately with covid-19.
Welcome back MY BROTHER !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! :)
great video thanks
Great job
OMG... It's like upgrading the BIOS on my computer, plus a VIN code...! Very informative... I will sleep a little less stupid tonite..!
Very nice thanks👍👍👍
Yes this is a blessing y'all very good I wish y'all come to Milwaukee and fix my 1994 sw2 saturn twin cam wagon
hey man this is great video i like
This was very helpful I have today exactly the same issue with the same vehicle I did check the wires and they are ok , so I got in the same conclusion I do have a scanner but I don’t have the programmer that’s going to be my next purchase
Eric, AWESOME really enjoyable to learn from a master as i was reading through other peoples comment some mentioned 120 resistor in the CAN communication what u think is a good thing to check when there is a communication problem before you change the module as u now we should see 60 ohm. cheeeers stay safe and healthy please.
Nice video.
Awesome...saty safe..stay healthy...
one thing to check before replacing the ecu is can com lines to the ecu..... good video,,. love your channel
Another excellent case study. How would an car present if one of the communication wires from the computer to the network was broken? Would the vehicle start? Is there any reason for checking those wires before condemning the computer?
I think it would crank over and start but the other modules on the data link would not communicate with it. I might be wrong though. I had a Saturn one time where the scan tool would not communicate with any modules but started and ran perfectly. I found one of the CAN circuits to the data link connector was broken. Repaired that and all good.
Sometime it starts but then it won't and if I had get engine control manual are u able to interchange or can y'all get me one
All vehicles using CAN or in this case LAN networks have 2 to 4 tiers of network, separated by speed. Usually main modules will communicate through more than one. Satellites sometimes not so much.
Good video just my personal opinion when Im cheking powers and ground I like to load the circuit with some current. The power probe is giving you that, but is not loading the circuit to say 100% is good. Here in the desert of las vegas green crusty is rare but it happen. Power probe saying there is a ground or power still not enough to me to call it good
Man you need an ig account, great diagnostic 👍👍 keep it up
You're goddamn Genius Gump … Good job man
Friendly suggestion for next video. Take pocket screwdriver and click door latch shut to disable chime.
I don't know if you noticed that with the old ECU the MIL wasn't lighting up. When you put the ignition on with the new ECU you can notice that the vehicles have two different MIL lights. The bottom one wasnt lighting up with the old ECU.
eres una chingonada primo!!! saludos
Thank you for sharing. I'd just add, for the final step, I'd wish you perform a voltage drop test on the powers and grounds for the ECM.
Back probing the wires is a voltage drop test. The ECM is the load. If he unplugged the connector and then tested the wires that would be unloaded and an inadequate test.
Also make sure the 5 volt reference is not shorted to ground causing the issue
Great video and diagnosis. Do you have anyone in NW suburbs of Chicago?
Just as a heads up, before condemning a module besides checking power and grounds (should be LOAD tested)...you should also make sure none of the voltage regulated module outputs (typically 5 volt references) are not shorted as well. Many modules will "shut-down" if their output voltages are shorted.
And check the communication wires going to pcm
The men of the video is the best ,
Useful, informative video, thanks Eric!

I really liked your video and I know this is an older post but I'm wondering if the j2534 programming tool would help me program an older vehicle. I have a 2002 Saturn Vue AWD 3.0L V6 which I had replaced the ECM (OEM Refurbished) but I can't seem to find anyone to program it and the GMC dealer isn't sure they could do it.
Trying to find out if it's dcm or engine control manual for 2007 2.0 manual or should I try what u did in this video?
Great job......could you put links to the pass thur device you used thank you.
So I have a 2009 Saturn Vue and thought the starter was bad (single click when trying to start it). I put a new starter in and hooked up the two wires around the top terminal of the starter (power I believe) and plugged in the wire with the plastic clip (purple wire). Went to start the car and it didn't even click. Went back under the car and noticed a black and white wire hanging down with the end of it looking like it broke off of somewhere. Any ideas where this black/white wire goes to? Also now I'm able to shift my gear shifter without having the keys in ignition and/or foot on the brake. Another thing is I was able to scan my car and it would read codes. Ever since that black/white wire is hanging my scanner won't read my vin/codes/any info on my car.
personal preference; I like to 'load' test my powers and grounds.
If im using a autel scan tool, do you need to use the pass thru to program a replacement module?
Hi I have 09 but it has a lot of rust in underneath and recently I found 08 with some issues ,wanted to know if I can fix it with the parts from 09
For a 2006 Vue. Would trying to start the car and getting no crank. But instead a smoking in the engine possible electrical short be caused by a faulty ECM???
Question. I have a 2009 saturn vue, rear latch is not opening. I checked the fuse, when pressing the open switch I can hear the latch trying to open but the voltage is low. Sometimes it will work on its own. Any suggestions or wire schematic you can provide me.
I would just do the 30 minutes procedure and thats it. Works everytime.
Super Like!!
What is the type of computer analyzer that you used and its cost?
Gavin I think we have a bingo !
Nice
I have a 2002 Saturn Vue to start it i have to crank it once and it doesn't start but if i take off the black cable from the battery tap it on the post and then try to start it .It will start every time but i don't have any power stering or gauges and the security stays blinking. need help fixing it.
What scanner do u recommend let me know
Hello Erick, Im having the exact same prblem, is there any way I can contact you ???
what are you using to read the codes and things with .. I have a cheap ass scanner i got at my local walmart .. it does the needs for my personal auto`s. But id love to be able to scan more system checks, dop more and reprogram ECMs with ... can you offer info on the unit you are using on a good unit close to the one you are using
Thanks
Like your videos,how much it cost to program a pcm on a car ,thats the only thing i can't do, just starting on a electrical problems on a vehicles...all the electrical diagrams i do it thru my phone thats a pain,....
My care wont start its a 2009 UVE XE. saturno same issue as the one in the vídeo algo the key is stuck and wont realice it frontal the ignición. Can you help me..
My 2008 Vue at the beginning was failing the crank, it was starting slowly, and I got a battery thinking that the problem was an old batt, but when I changed for a new one, the problem continued and now the car doesn't start at all, the battery's charge is normal, but it doesn't start the engine, I guess I have to change the starter, I hope after doing this my problem is solved.
Yesterday my battery went dead I tried to start my car doesn't crank and my gauge and my gasoline meter is AS empty and I got food tank do you know what can be the problem
GOOD LOOKING OUT , just one question do i need an lsid to do this programming and thanks again !
No sir , not for this one
@@NewLevelAuto HELLO Keith, hope every thing is good and good luck with new home question one person wrote u can do this programming with LAUNCH X431 that he has and i have the new LAUNCH X431V+ HE SAY THAT WITH LAUNCH you can write the old VIN # without buying any online software if YES is LAUNCH will do other CAR maker too or only GM CARS any information would be greatly appreciated and buy the way I really enjoyed the seat wight life course other day. cheeers and stay safe and healthy.
@@NewLevelAuto THANK YOU SIR , ALWAYS GREAT TO HEAR FROM YOU AND THANKS AGAIN KEITH !
Mine does crank but no start no communication. Tested all connections everything pans out. ECM?
Thinking this is the issue with mine. But before it stopped starting, an auto store read a code for the throttle actuator needing replaced. But then my Vue did all these same things when trying to start it.
Hi there! I have the exact same problem on my Saturn Vue 2008 2.4,I live in Georgia ( country ), i’m seeking for help,is there any way that i can contact you ?
Why do I have to tap my fuse box and everything light up some times can some one help me. With my 2009 Saturn vue xe 2.4l 4cylinder and stability track comes and go.
