Peugeot Expert (no start, no crank, no communication)
Вставка
- Опубліковано 10 чер 2020
- This Peugeot Expert van wouldn't crank, I scanned for faults and had no communication with the engine control unit, next I checked fuses and all were ok.
So then I went straight to the ECU and looked at the CAN Bus waveform, it was messy.
The next thing I did was unplug the ECU and the waveform improved, I went on to check for powers and grounds at the ECU,
I was missing a power supply so I jumped the wire with battery voltage.
The waveform improved and the van started, so I just had to find the broken wire.
I soldered the broken wire and cleared the fault codes, the van ran fine.
Thanks for watching. - Авто та транспорт
excellent advice and absoloutly no BS like so many others,its guys like you that make UA-cam worthwhile.Thanks a mill.
This guy is a fantastic mechanic, technician. he has a very good calm mindset and hardly has any fancy equipment, he would get a job in any garage with these skills. There is no shit just straight talking. Perfect.
Thanks Chris
great diag with out the aid of a wiring diagram outstanding
Well done Matt great diagnosis
Thanks mate
Great video Matt, thanks for sharing, I have a Citroen Dispatch ( 2014) no problems at the moment but ill be checking it out when the weather improves! Mick
Thanks for watching Michael
Great job Matt...seems you get all the broken wire jobs...🤣🤣
I go out of my way to look for them 😜 thanks for watching
Nice work Matt. I have been so well impressed by your use of the wire tracker I bought myself one. Not the same manufacturer but I think they all function very similarly. Thx. Cheers Pal
It's been a big help, I seem to be using it a lot on my wiring jobs lately
@@mechanicmatt871 Hello. Was this a hdi engine ? How often do you come across dead ecu’s, and is there any pattern to these failures ?
Thanks.
Good job Matt
Thanks for sharing
Thanks for watching
Great video Matt I'm tempted by that power tracker as it would have saved my embarrassment at a job yesterday (I'll post it tomorrow) on a transit cheers my friend, Sandy
I forgot I had it, it was in my shed and I found it doing a clear out during the lockdown. Ended up using it a lot now. Thanks mate
Nice find matt 👌👍
Thanks for watching
Great find mate I like the power tracker can be a life saver 👍👍👍👍
Thanks mate, it's been a big help, I keep getting to use it lately
Thank you that was a good video you really made it clear
Thanks for watching Greg
Hey Matt Same van same place same tug on same corroded brown wire should be 👍. It's for pussey cat charity lady it's cost her £ 2000 so far in a couple of garages with still no fix and same symptoms as yours. So thanks for info.
update.. all buttoned up no codes all seems good and back on the road thanks again.. But what on earth caused all this on the same little brown wire as in your video?
Hi there I wad wondering if you cold tell me what 2 wires you first used to bridge out? I have the same fault with my friends van thanks
thank for video
Thank you Stephane
Were can i get pin layout having similar issue
Great video Matt. I have a similar problem with a 2010 Fiat Scudo except mine cranks but won't start. I had a new key made this week in case that was the problem but the key guy showed me it's the body control module not working or not getting power! So it looks like a broken wire again! Since you made this video gleaned any new routes for testing? I now have a similar tone tester for broken wires but I'm struggling to get the snail clamps to release on the ecu plugs a video on releasing various plug fittings would be helpful. Keep up the good work. Cheers
Great video but it will help if you also show where exactly the fuses you checked are located and where exactly you connect your oscilloscope to check if it gets volts. I have the same problem and really need help. Thanks once again for the awesome videos!
Thanks for watching, I'll have to start showing the wires that I connect to. Cheers Matt
@@mechanicmatt871 Thanks Buddy, I have a situation that which a 207 had flat battery symptoms, and even after replacing the battery the next day all is completely dead....no crank, no ECU communication, and continuous economy mode after a few seconds. The inertia switch was previously removed by the previous owner
you can hear a relay clicking under the dash when turning the key and the instrument panel does turn on.......any ideas?
@@jacqueshanekom822did you fix this probem? I have ecaxtly the same issue with my 207
Wish you was in Liverpool mate
Would like to see an in depth use of that power probe short finder thanks for the video .
No probs, thanks for watching
Iam vary great full good master u have Peugeot 206 with similar problem like this my is permanent fault communication with the column height ECU on bsi I check all the wireing OK I change the bsi and comm 2000 not OK pls what can I do next need help pls
Good video, hopefully it`s the same fault my job has :)
Hopefully, it may be a common fault. See if any wires are broken near the bell housing side of the gear box when you open up the wiring harness. Thanks for watching
@@mechanicmatt871 All wires are fine, :)
Good work Matt! Can you share what diagnosis program/Appliance you used at the start of the video and what connector you used? I'm searching for something to diagnose my own Peugeot expert II for a different, but similar fault.
I started checking in this with a launch scan tool, to get an idea where to start. Then I used auto data so that I could check powers and grounds and can bus at the engine ECU.
I don't have access to auto data any more, I have been told that it doesn't have pin data now, it only has wiring diagrams.
Thanks for watching
So ok i have just had this issue come up with the dashboard looking like disco light flashing on & off with lost mileage ect ect ect, it turned out the be the wiring loom on the ABS pump but also could be the ECU loom as well because both looms are connected, i have not looked to find what's causing the issue as yet, but if i keep the loom up in the air it stops the fault so just zip tied the loom up for now,,,cleared all codes an everything fine now!!!! Hope this may help some folk out there!
Good to hear from you sir I mean the name of the wire tracker you used
www.amazon.co.uk/PWP-PPECT3000-ECT3000-Electrical-Circuit-Tester/dp/B0719JV971/ref=mp_s_a_1_15?dchild=1&keywords=power+probe&qid=1624777520&sr=8-15
This is like the wire tracker that I have.
Thanks
I have the same trouble today the launch no had comunication with ecu it is a 408 2012, go try it tomorrow
I had a similar problem with 2012 Expert no crank, solenoid clicking. Has already clean battery earth on drivers floor. Battery 12.8v drops to 11 ehen trying to start. Got new battery still the same.
Measured from battery neg to body some resistance showing. Varied when batteryneg lead moved. Stripped off neg lead and replaced with 25mm flexi.
Crimped big copper lug. Started fine cranked fast. Put original battery back and started fine.
Neg lead had gone high resistance!! Job done and I was thinking new starter motor. 😂
I wonder if some body ecu problems, sensor problems are created by Neg battery lead problems.
I had a Citroen today, no crank.
The engine block had battery voltage when cranking. It had a bad ground.
Thanks for watching and your comment
Hi Matt which pins on ecu was missing a power feed your answer will be highly appreciate thanks
Hi Joel, I can't remember now, all I know is that it was a brown wire I think in the centre plug.
My berlingo ii no cranking and battery lamp flashed but i hear noise in fuse box under the hoad your advice pls.. Regards
I would check for battery voltage at all of the fuses and make sure their is a good ground connection near there. The noise may be a relay clicking on and off due to bad contact
good master the pls tell me the wire tracker you use i wii be very greatfull
I use the powerprobe wire tracker, it has been very helpful. Thanks for watching
Matt what year was the expert you were working on. Mine is a 08
I'm not sure of the year, it may be slightly newer
I am having the very same problem. Can I ask which color wire on the brown block loom was actually broken it would help me a lot. Thanks for the video
Hi Patrick, I really should have shown a close up of that wire whilst making this video. I don't know off hand but I'll try and find out and let you know. Thanks for watching
It looks like it was the brown wire in the brown (centre) plug. This is powered with the ignition switched on. Try giving it power if it hadn't already got power. I jumped mine from the red wire with 12 volts on the black plug. Try using a fuse in the jumper like I did. If in doubt you may get a free wiring diagram from carmin STD app in the play store.
@@mechanicmatt871 thank you so much matt for helping me out and your great video. I appriciat it!
Some job matt
It was thought to have a faulty ECU, turns out to just be a broken wire, thanks for watching
Le doy arranque y no ases nada lleva algún fulsible en la bateria algo d s eso
Hi Matt, hope you're well! I was wondering if there was a way I could contact you directly? I am currently experiencing the same issue with my Peugeot expert. No communication with ECU. Fuses are all ok (ECU has also been sent away and scanned - it is ok too) I'm really at the end of my tether here and can't seem to get help from anyone locally. I am based in Kilmarnock, Ayrshire. It would be good to talk with you and hopefully acquire your services? Thanks, Andrew.
Hi Andrew this one ended up being a broken wire, it was a small brown wire in the centre plug in at the ECU. This wire is powered with the ignition switched on, to let the ECU know to switch on.
It was not any of the thick power wires or thick ground wires.
If you take of the cage at the ECU and remove the electrical connectors, it may be worth trying to put power through a fused jumper wire to the brown wire and see if it starts.
If it does and you want to find the break in the wire, on this van it was near the bell housing at the top of the gearbox.
Thanks for watching,
If this doesn't help let me know.
Can you share on what pins do you have to have power and on what pins ground. I have the same problem
Hi, I started at the engine control unit, the four thick wires, two power and two grounds.
Then I checked for the 12 volts feed with the ignition switched on, I think that was pin 69. Also I checked for a good looking can bus signal. Thanks for watching
I dont have any power on the wires that are going to the ecu, abs module is geting power, any idea what could it be? All the fuse are oke and no demaged wires found. Coms with all the modules are oke, only the ecu is the problem
Definitely needing a wiring diagram and follow the wires back to a fuse or relay.
You could try jumping power to the two thick wires that should have it.
It's easy to test the two that should be ground by connecting a test light to battery positive and seeing which wires light up the test light.
@@mechanicmatt871 any idea which colour are these thick feed wires or ground. Sorry for all the questions and thanks for your time
Pls sir tell me the name of the wire tracker you use
Puegot expert ..engine speed no signal..ground to earth no short...after trying to jump start.
The problem was a broken wire?
Yes Salvatore, just a broken wire stopping this van from starting. Thanks for watching
Our 2011 peugeot van was exactly that, a corroded (1cm length) brown wire in that same location. So what is going on?
That's good that you fixed yours, glad the video helped
@@mechanicmatt871 ive got the same problem a wire from stopping it from starting i had someone out and located it towards the air box me stupidly drove off with out asking witch wire it was not its cut out again and refusing to start
where do you get the tool to find broken wire
Hi Mark it was probably from Amazon, it's usually Amazon or eBay that I get my tools, I read through the Amazon reviews before making my mind up when getting something new. This power probe wire tracker has been very helpful. Thanks for watching.
Where did you get that beep tester?
It's usually Amazon that or eBay. That I get my tools from. Thanks for watching
Tengo el mismo problema ,lastima que este en otro idioma y no en español
El problema que tuve fue que el pequeño cable marrón en el conector central no tenía energía
Gracias por ver
@@mechanicmatt871 gracias por su respuesta
No pin 😂 no nothing just generic info
