@@64021233 enpäs tiiä. Mulla yks loota viel odottaa korjausta niin voin siitä koittaa asiaa tarkastaa. Se on vaan vähä eri mallinen. Niin en tiiä kelpaako suoraan vertailuksi. Ja mitä tarkotat että maa puuttuu ?? Näissähän on hyvin tyypillistä että vaikka suuttimelle menee kokoajan virta ja se suuttimen - palaa eculle missä on sitten mosfet puolijohde joka kytkee sen miinuksen oikeasti miinuksen silloin kun halutaan ohjata suutin.auki.... tavallaan ohjataan niinkun sitä maa puolta vaikka yleensä valot yms muut vemmeet toimii just toisin päin

@@ElectronicMechanicFinland Kiitos vastauksesta. Eli sähkökaavion mukaan MR7(Ruskea liitinkampa), GR19 ja GR26(Harmaa liitinkampa) nastojen pitäisi olla moduulin sisällä maadoitettuna. GR26 on piirretty erikseen suoraan maihin moduulin sisällä, kun taas GR19 ja MR7 ovat yhteen piirretty moduulin sisällä maihin. Kuitenkin GR26 ei ole yhteydessä GR19 tai MR7 nastojen kanssa. GR19 ja MR7 ovat yhteydessä toisiinsa. Yksi kuva selventäisi tilanteen paremmin kuin teksti 😅

@@MarkkuPenttila-t6r en oo näihin sen enempiä perehtynyt. Mutta tässä boksissa oli ainakin valmiita paikkoja piireille mitä ei ole ikinä asennettu. Että ilmeisesti varustelutasosta riippuen on myös rnemmän kalikoita samin sisällä. Ensin luulin et ois vaan ihjelmointi ero mutta taitaa olla kyl ihan fyysisiä komponentti eroja myös. Ja ihka ensiks kattosin miginy pinneihin se pa tankin tason anturi tulee. Ja niitä seuraisin piirilevyllä ett mille piirille se tulee. Toden näköisesti anturilta tulee kuitenkin jännite tai vastus tieto joka menee joko suoraan jonkun mikrocontrollerinnanalog inputtiin tai sitten se menee johonkin analog - > digital muuntimeen josta digitalintietona microcontrolliin... Jos on joku muunnin välissä niin senhän voi kyl vaihtaa ilman mitään kodailua.. ja toden näköisesti sellanen analog to digital muunnin on kuitenkin pintaliitos kikkura ja on erittäin mahdollista että on vain hapetumaa jalkojen välissä. Mikroskoopilla tai jollain muulla hyvin zoomavalla vehkeellä vaikka kameralla käyt huolella läpi koko piirilevyn ja hapettumat peset pois ipa alkoholilla ja hammas harjalla . Isoprophyl alkoholia saa ainakin hyvin varustellusta apteekista

Hi. Nice to hear and thanks for comment =)

@@ElectronicMechanicFinland Greetings to Finland from Moscow! You've explained everything so smartly and clearly. There is not a single specialist blogger on the Internet like you. I do not know English, but I understood everything with the translation anyway. THANKS, buddy!!!

Спасибо, дружище!!! Вы-лучший!

Реально за такой ремонт сдирают 10 тысяч рублей. Проще выбросить телевизор. Мне всё обошлось 1648 рублей за новые светодиоды и плюс 6 часов труда... (Привет, выбрасывающим на помойку новые телевизоры....

Теперь, бухаю от радости. СПАСИБО!!!!

Can u tell more about it

not fixed. car shop programmed presense feature off to get rid off fault codes

With soldering iron and sawing needle. I used needle as leverage and iron to melt solder

It was no crank no start situation.. only wisit workshop logo in dashboard

Thnx :)

Laita mailia niin palaillaan asiaan electronicmechanicfinland@gmail.com

????

Hi. Sorry i missed your first contact.. i cant fix it. There is tampering circuit inside off pcb micro controller.. if bms board is removed from battery back it needs to be powered all time with auxilary bench power supply. And still if there os same fault that regulatorncircuit failed and full bat voltage.directly to canbus module and micro controller it is almost quaranteed to be no fix. But you can send email to my channel email if you want to chat for more... Adress is electronicmechanicfinland@gmail.com Cheers and have a nice day

i.am sorry but i dont really remember. i can try ask from store where i got them if they have my shopping history easily available. I will post component numbers if i can have them

@@ElectronicMechanicFinland Many thanks

@@paulsimon1272 sorry. No luck i have no information to that. Only old markings what also is visible on video

It did not fix problem =(

That is one way what o have also thinked trugh. I have one module waiting same repair and i will try to enter Back side off module... I'll post video from it when i get it done

Le problème est que la voiture ne démarre pas à cause de contacts de relais défectueux. Le relais est vraiment difficile à changer et les modules de remplacement usagés ne sont plus disponibles. Cela signifie que la voiture est une poubelle si le relais n'est pas changé

@@ElectronicMechanicFinland vale voy a intentar se lo consigo te mando un mensaje 😅

Just gunk. No screws

In my quiq Google search i noticed that airag and belt pretensioning module is suplyed wia under dash fuse box. Fuse n.3. 5amps... So it might be nothing to do with your under hood bsm module. Are you sure that your airbag module is powered trough bsm module? If it is what is fuse number?

@@ElectronicMechanicFinland thats what i saw in autodata. Ill check what fuse exactly it say it is amd ill post it here. Maybe im wrong and miss see something.

Riippuu kai vähän että onko noi isot sulakkeet vai pienet?

th-cam.com/video/tA0cG2IyHeI/w-d-xo.htmlsi=q7pZ2V22n5sPoDH7 Tuossa täysin sama ongelma ku minulla ja tämäkin kaveri väsäsi tuommosen kyseisen rele systeemin 30:see sulakkeeseen ja siitä virta juurikin tuosta sulakerasian tapista.

Why bother? Inside off microcontroller have rom or flash memory area for store programming off device and i have no orginal sorce code for that. Offcource it migh be possible to reinvent the whole micro controller functionality and write totally new code but it would be extremely difficult

I changed one bms canbus trans reciver chip and now batt blinks some error code. It needs bosch computer software for diagnose. So no progress

@@ElectronicMechanicFinland Hi. i've found one bosh computer software for diagnose on the web...

Really? What u can do with it and where u did found that? Can u share it?

Salut. Désolé, mais je ne peux pas faire de différences entre les unités. Je n'ai réparé que ces deux appareils que l'on peut trouver sur ma chaîne

a year late but im busy with it a sparta bike almost brand new but dead battery as wel prob ballanced wrong but im also installing a allie expres bms so i dont have 2 pay money for service because they block the battery if u dont pay its all mony making busnis u can better buy a diffrent pack built ur own battery u have alot of cells when u dismantle a pack so chance is that 1 group is bad and maybe 1 or 2 cells have low voltage buy a spot welder for 20 bucks and have fun on saturdays in shed🤣 u build a pack in 1 hour if ur handy less

I have doldering station with integrated desolder gun like link above. fi.farnell.com/proskit-industries/5ss-331-dg/spare-desoldering-gun-140w/dp/2474821. It will usually do the work but gets easily clogged and needs maintance. I prefer solder wig always when it is possible. It will do the trick and dont get clogged

One done and a other one needs same thteatment but i dont think that i am willing to film it xd or if i do then it will be edited much shorter video =)

I have done now two units and third is waiting on my desk =/

Probably you are using 20v measuring range from meter and backlight circuit is higer voltage so meter cant show you voltage because it is overshooting. You need to turn multimeter to dc voltage and i am quessing next bigger range to be dc 200v... Range selector needs to be set higher value what you are actually measuring. Otherways meter overshoots and shows over 1 what means measure reading is higher that one selected range voltage. In that case meter tries to tell that voltage is higher than 20 volts...... If your range switch is set to 20 volt range

He somehow deactivated heating circuit from camera... It can be done with propper diagnostic tools... Camera itself is really fragile and i dont suggest to open that. Or atleast i didint found any fault inside off unit

Jaahas xd ranskalainen aina yllättää. Siitä ei valitettavasti ole kokemusta

Any generic automotive relay with 12v coil voltage rating and something like 20 or 40amp current handling capacity... Ou and normaly open relay contacts so it Will Make contact when energized

@@ElectronicMechanicFinland i had 20amp twice in a row and keeps burning it i can't understand why

hi . i think that fuelpump is not your problem becouse it is protected with 5 amp fuse what is not enough to brakedown relay.. But insteed Fuse n 10 what is 30 amp fuse and it is for engine managment control devices example ignition coils, injectors, allkind a solenoids and walves. It is big enough for that kind a problem that it melts relay but not 30 A fuse. Check with disconnected car battery what is resistanse mesured from fuse n.10 and between car body (minus or ground ) if ohm reading is low as 0,5 ohms then it could melt relay but not blow fuse. I dont know right reading for ohm meter but i assume that it should be something like 5 -20 ohms.... if you are measuring that low ohm reading that means that tahat n 10 fuse circuit is somehow short circuited to ground and that might explain whay bsi modue relay is failing and that explains why that new external relay is also melting..... please do the mesurment and report ohm reading and we can try figure it out

@@ElectronicMechanicFinland what do you suggest in this case to be done

Well. If ohms reading is low then IT need to figure out what Part is causing that short circuit. That might be tricky without shematics but i would first just unblug connectors. Ign coils. Solenoids and and basicly everything what is related for engine management..... And see If resistance Will rise up

I dont think that connections are problem in sam units. And old word sentese is "dont repair it if it is working" xd i dont have enough knowledge what comes in really faulty sam units. I havent repaired even one yet. Even that unit what i opened wasent faulty and real fault was bootlid control module

cosa intendi per relè 5?

@@ElectronicMechanicFinland HI. Inside the Siemens control unit there are 5 relays. One powers the air conditioning fan but I don't know which one it is. Do you know what each of the 5 relays powers?

I have one unit opened on My workbench and i can try figure it out. Please give me couple days and will write what i can find

Hi friend. This module what i am working on is difrent and there are 13 relays=( but i watched that My video and you can see fuse F11 40amps and it is for Air blower- Air conditioner. The fuse is located near by 30A fuse and relay what is directrly under IT IS that what powers The fuse and Air blower.

In My video Time stamp 14:51 you can see empty slot in left down corner what is for ecu and Fuel pump. Right next to it on right side under The 30 and 40amp fuses IS The AC blower relay
