Hi. This is usually a fix for other codes that show up on this model, ie B1037, B103B and B1039, (stating high resistance on diagnostic tool) Mine was a B1037 fault showing up as right side airbag, I would also recommend that both sides are done., the same fitting is located on the other side., this will save any future problems., Plus a reset tool will be needed to removed the SRS light. Thanks for the clip btw, :-)
9103 9202 9123 91C3 I have these errors, and I can't erase them with diagnostic tool, only 9007 was erased. Can you please help me what can be the problem? Thank you. W203 2006 (sport coupe cl203)
@@AlexAndreiZAR 91C3 electric ignition of the seat belt pretensioner of the left rear seat, resistance too high. constant value. 9202 electric igniter of the seat belt pretensioner of the right rear seat, voltage too low. constant value. 9103 driver's airbag electric detonator 1, resistance too high. constant value. 9123 driver's airbag electric detonator 2, resistance too high. constant value
@bsmobilecz the errors with resistance to high means that an electrical connector is faulty. Best remove it and replace it with another one or solder wires directly and then put a heat shrink tube to insulate. On the errors where you have low voltage you need to check battery output...and alternator output.
@@AlexAndreiZAR Thanks for your answer! Do I understand right that I should solder wires on connectors of rear seats, and on driver's airbags I should check outputs? How much should be alternators output?
@bsmobilecz battery and alternator output needs to be checked. Battery should have with engine off over 12.4V... minimum 12.0V. With engine on, alternator charge should be minimum 13.4V and maximum 14.5V. Again, where resistance is to high you either remove and install new electrical connector or solder wires directly. Cheers.
Thanks for the video, do you have any idea what the dtc b106D means? Component b48(front passenger seat and child recognition) has short circuit to ground, how should you proceed to fix it? w203 non facelift
Hi. In your case try to check integrity of wiring and electrical connectors going to the passenger seat. If that doesn't work than most likely the sensor within the seat is faulty. You can try sourcing a different seat from a breakers yard. Also check this link. www.mercedesmedic.com/child-seat-occupancy-recognition-sensor-problems-and-solutions/
What is the manufacturing year of your vehicle? What is the error code on the scanner? Is your alternator charging well enough? Proper charge is around (13.4-14.4V). Is your battery in good health state? At least 12V with engine turned off.
@@AlexAndreiZAR Yes everything is fine . Anyway 2003. I forget the error code i can tell . It looks like a cable is broke . But i doesnt checked it already.
Hi, I have problem with my C 180 we have localised that the SRS problem is the right passenger seat and the part where you install the babyseat can I do the same procedure? Regards Sven Sykora
there might be the case where you can find an elm32 and get cheap android obd2 via bluetooth to scan and delete codes. First of all airbag cannot be faulty. Airbag is textile part. The inflator is connected to electrical loom. Electrical loom deteriorates over time. You first need to scan for error and see exact which of the airbags is giving you error. If your C Class is 2001-2004 it is either left or right side curtain airbag, but it can well be left side or right side door mounted airbags. If your C Class is 2004-2006 then it can also be the weight sensor in passenger seat which causes SRS error. Please do check with OBD2 Diagnostic tool for errors and only afterwards proceed to fix physical electrical problem.
And also how many liters of oil with filter trica? Manual says 8L, but says too much oil and asks to remove 1L, with 7.3L it is fine without accusing anything on the panel... Have you had this experience with W203 C-Class C320 Elegance V6 3.2L M112 2001?
lamentablemente no he tenido el motor del que hablas. Consulte el manual del propietario y vea allí cuál es la cantidad de aceite recomendada. consulte también el sitio web de ravenol, mobil 1, motul, yacco y vaya a su selector de aceite, allí debería poder ver la cantidad adecuada.
I have trobel code B1027 the resistence value in the ignition circuit countaining component R12/14 drive airbag ignition squid 2 is too high what is problem bro...what can i do
R12/14 is referring to steering wheel squib. Basically you have to go to an electrician and check if Mercedes provides a repair solution for the electrical connector which connects directly to the steering wheel. It needs to be changed as it might not make good electrical contact.
Hello Alex, i've got the ame fault code comin on my W209 which is based on W203 by the way. Do you think this might be the origin of the problem ? Thanks.
So why in the world would you just cut the plug out and then solder the wires back together? Why wouldn’t you just fix the plugs make it so that it has a good connection again I’m not understanding why you’re going so far is to cut the wires in the plug out and then strip the wires down and started them together. Makes no sense to me just fix the plug. What are you doing to the system by taking the plug out? I don’t understand you’re confusing me with this whole thing.
You can remove the old plug and install a new plug in. I eliminated the plug and soldered the wires together to avoid the fault coming on again due to humidity or lack of a good electrical contact. Those electrical connectors are not the best in the world. Hope it now makes sense.
Hi I have a SRS light on my C200 Kompressor and wondering if you know if I have a similar issue with the wires, it's been diagnosed on a BOSCH machine and has 2 error codes, first is B2D92 and it says Unknown Fault, second is B107B and says Instrument Cluster: CAN Signal Missing. Any idea on where to start?
@@wing0zero you must scan the car with DAS C3 Mercedes diagnostic system. Also with Mercedes diagnostic system it will walk you through what needs to be done.
I just bought an old W203 and had no idea what this meant and was scared .You are so clear and simple after listening to you Sir .Thank you .Vetri South Africa 🙏🇿🇦🇿🇦🙏
Buenas magnifico video le explico. Le cambiado la puerta que estaba abollada de mi mercedes la del desguace mismo modelo color año y referencia de airbas igual pero el macho de la puerta de la nueva de airbas es diferente la clavija he cortado la clavija macho de la de antes cortado los dos cables de la nueva y adactado la clavija enpalmando los 2 cables a esa clavija y bien de hecho .he enchufado a la hembra total al poner la bateria tirar al contacto arrancando me ha salido fallo srs en rojo es por que lo tengo que reprogramar con diagnosis? He empalmado mal los cables o clavija? Es por que al poner otro airbas hay que reprogramarlo o esta roto ? tengo que poner el de la puerta antigua? Que podria ser la clavija se ha podido desprender de los contactos como usted dice, vuelvo a revisar . Podria quitar el fallo o lo llevo al taller a que lo reseten no soy mecanico soy manitas que arias??? Un saludo y muchas gracias por tu video pero por ahi van los tiros es la puerta del conductor clavija airbas amarilla le adaptado la de la puerta vieja que es rectangular el macho la de antes era ovalada y le adactado la de la puerta anterior y el airbas de la puerta desguace misma referencia numerancion igual.
Después de instalar una nueva bolsa de aire, incluso si proviene del desguace, debe colocar la herramienta de diagnóstico obd 2 y restablecer los errores. Si los errores no se restablecen, cometió un error al realizar los cables. saludos y gracias por tomarte el tiempo de comentar
@@AlexAndreiZAR bueno pues muchisimas gracias el lones lo llevare a ver si lo reprgram con diagnosis y borran el fallo y si vuelve aparecer pues tendre que volver a revisar y poner su antiguo airbas ya les explicare que he hecho. Es que poner puerta y aleta me cobraban 400€ aun llevandole las piezas y lo he hecho yo de lujo sabia yo que saldria ese fallo me lo imagine por no averle pueste el airbas anterior pero tenia mucha faena y vi que la puerta del desguace tenia la misma numeracion el airbas muchas gracias un saludo y sigue con tus videos esta muy bien explicado
Hello, I have a problem with the error B1027 on the w203, could you explain to me in a little more detail how I can try to solve this AirBag error myself...?
The error is on different airbag. Can you show me error description? It's simple, you find out which airbag creates the error, then go to electrical connector. Eliminate the electrical connector, solder wires directly and then delete error. Work on your cars electric system with battery disconnected. Cheers
@@AlexAndreiZAR The error description is “AirBag ignition circuit 2 , driver side Resistance too high “ B1027 And the SRS control light on the dashboard is on…
@Viks b1027 error code is for R12/14 component which is steering wheel driver airbag. You can buy a used airbag from breakers yard and replace it and the check for error again(delete error and rescan). If this works then your problem is solved. If not, then the the rotating squib wiring harness is faulty (this is on the steering column just behind the steering wheel).
Bonjour Alex, J'ai le code défaut b1035 "dispositif d'amorçage de coussin latéral avant gauche: résistance trop forte". En"défaut permanent" sur une classe c320 4 matic break de 2003. Le problème est uniquement le connecteur que vous supprimez? La panne provient à 100% de ce connecteur? Il suffit de supprimer le connecteur et de brancher en direct les fil les uns aux autres? Ensuite rebrancher la batterie et effacer le défaut à la valise diagnostique? La panne ne peut pas venir d'ailleurs ? Merci Hello Alex, I have the fault code b1035 "front left side air bag priming device: resistance too high". In "permanent fault" on a class c320 4 matic break of 2003. The problem is only the connector you are removing? The failure comes 100% from this connector? Just remove the connector and connect the wires directly to each other? Then reconnect the battery and clear the fault in the diagnostic case? Could the breakdown come from elsewhere? Thanks
Hello. Yes, connectors are problematic. This b1035 is mainly happening on the w203 non facelift. Once you eliminate the connector and make a direct connection you just have to reconnect the battery, remove error codes with a diagnostic tool and all should be working without any errors. Thanks for commenting and watching my RU-vid video. Cheers
Merci beaucoup pour votre aide, j'avais une erreur B0137 au côté passagé, j'ai suivi le tuto et j'ai pu effacer l'erreur à l'aide d'une valise diagnostique. J'ai uniquement nettoyé et démêler les connecteurs, cela à suffit
1. Asegúrate de que el motor esté apagado y la llave esté fuera del encendido. 2. Localiza el botón de reinicio en el cuadro de instrumentos. Es posible que esté cerca del velocímetro o detrás del volante. Este botón puede tener la forma de un pequeño orificio o un botón físico. 3. Inserta la llave y gírala a la posición "1" (posición de accesorio) sin encender el motor. 4. Mantén presionado el botón de reinicio durante aproximadamente 5 segundos y luego suéltalo. La luz de avería SRS debería comenzar a parpadear. 5. Continúa manteniendo presionado el botón hasta que la luz de avería SRS deje de parpadear y se apague por completo. Esto puede llevar unos segundos. 6. Una vez que la luz de avería SRS se haya apagado, gira la llave a la posición de apagado y retírala del encendido. 7. Espera unos minutos y luego enciende el motor para verificar si la luz de avería SRS se ha restablecido.
Hello guys I have been complaining about my W203 C200 with it going in limp mode. Guys fuel pump malfunctioning can cause this. Since I replaced the pump with the universal one I have never experienced limp mode
Salut. Din păcate am vândut masina, însă, orice w203 trebuie sa vina însoțit din fabrica de schema de siguranțe. O poți găsi pe usita de vizitare a panoului de siguranțe din habitaclul mașinii, mai precis, cum stai la volan, deschizi ușa de la sofer, scoți capacul de pe lateralul bordului și în suport pe capac trebuie sa fie schema împăturita. Dacă îți lipsește o poți comanda de la orice magazin de piese auto după codul A2035450200. Bafta
What do you mean? System is active and working. Fault is gone. Remove the electrical connector, solder the wires together, delete error with diagnostic tool via OBD II port, job done!
Salut. Este problema de conectare a mufelor. Sistemul este cu comunicare pe canbus. Dacă un contact este imperfect atunci apare aceasta eroare. Fa o scanare și vezi care airbag iti este afectat. În video am eliminat o mufa și am legat firele direct între ele. Am șters eroarea cu o diagnoza delphi și m-am scăpat de notificarea srs din bord. Stima.
My c220 will not start lately, the battery is new, everything lights up in the dash but the starter will not crank :( I also get the same error in the dash, could it be the same error or do you think it could be the breaklight switch? I have ordered a obd2 scanner but could it be a quick fix like this?
Stormer324 check the fuse box for blown fuse which is designated for the starter motor. Srs is for airbags and has nothing to do with engine starting or brake system!!!
Stormer324 have you finally solved the problem ? I’ve encountered the same issue recently and finding it difficult to solve. Your ideas will be helpful.
Hi Emmanuel. CAN Bus is a generic term. CAN Bus means Controller Area Network. The BUS stands for means of transportation for transmitted data. Development of the CAN bus started in 1983 at Robert Bosch Gmbh. The protocol was officially released in 1986 at the SAE conference in Detroit, Michigan. This means that you don't have only 1 Can bus on your car. So in order to help me out please tell me the error code which you got from the scan tool.
SRS actually means - supplemental restraint system. It can mean a lot of things. My SRS error light was refering to driver door airbag having faulty connection in plastic clip connectors.
@@AlexAndreiZAR ye, i understand what you did but I would like to know if I can modify the installation in case it is my airbag that is giving the fault.
Good video! It helped me quickly identify the location of the problematic connector. I didn't cut the connector, I just cleaned and tightened it better. If the problem repeats itself over time, I will solder the wires. PS. It is not mandatory to remove the door seal.
hello friend I need help. I have the c240 2004 and the left rear door was hit but I got the door fixed it Works now. but the srs drive to workshop light is on, does this also work for the back left door?
@@airgundestruction2405 it is not bypassing the sensor. It is bypassing the connector due to imperfect electric connection. Please do scan your car for error before doing anything.
Just brought a 2003 mercades c240 This error is on my dash I see that this is the problem? I know for a fact that my motor and transmission is good Could this cause the check engine light to turn on also?
Toy Gun my engine check light didn’t come on. My seat belt wire was disconnected under passenger side seat ,SRS is dealing with something with the seat belt system
The SRS is strictly refering to airbag safety systems. It has nothing to do with the engine. If your engine light comes on you should do a scan with Xentry/Star MB Diagnostic Tool or any OBD scanner and search for the given error codes. In most cases cause of engine check light can be a faulty Lambda Sensor, or a MAF sensor.
Hi has anyone had this problem and what did you do to fix it ? SRS light is on The component or signal line to the component S68/4 ( passenger side seat belt buckle restraint system switch) has open circuit or short circuit to positive thanks for any help I can get!!!
Joe D. Hi. What you are speaking of is different fault which is shown in the video. You have a faulty connector or the seat belt restraint has corrosion on ground. Please do a Star Diagnosis check diagnostic and give me the fault code so I can better help you. BR. Alex Andrei Zar
Alex Andrei ZAR thanks for the reply but I found it . It was the connecter under passenger seat It was actually broken and wasn’t connected at all so Idid what you did in the video to it and it works now SRS light is gone off and ran a diagnostics on it and it passed thanks alot for your help and video ⭐️⭐️⭐️⭐️⭐️
@@joed.2830 Have you ever done anything like this before with sawder machine? I have no experience but in very handle and think this is very easy fix that I can handle
Salut, poate poti sa ma ajuti, masina e un w203 facelift am da din setari heat booster cu testerul si cand am terminat codarea mi a aparut in bord mesajul SRS, problema este ca cand dau scanare cu testerul nu imi da nici o eroare totul arata ca e ok dar mesajul tot este in bord. Ce as putea sa fac?
SeRo Lunarrosa din pacate nu te pot ajuta fara un cod specific de eroare. Recomandat sa scanezi cu diagnoza star si nu cu una generica. Heater boosterul e preîncălzitorul de bloc motor. Srs este defectiune de airbag sau contact imperfect la vreo mufa sau cantarul din scaun fie cel de șofer fie cel de pasager. Acest din urma defect e specific la w203 facelift.
Just did it in my car but it remains the same. What I discovered is that current did not reach this connection from the main source that supply current to the driver’s door. What step do I take.
Hi! Not being there surely doesn't help me to provide you with a fair answer. Do a scan with a diagnostic tool and check for errors. Tell me what is the error code. Be mindful, if you did this like I've shown in the video you need to connect a diagnostic system, scan for errors and erase errors. Whatever errors do come back they come back due to present or existing defect. Thanks!
Yeah, thanks for your response and concerns. I tried to erase the error but was impossible as it showed error is permanent. THE DIAGNOSE SHOWS: ( RESISTANT OF THE DRIVER’S DOOR AIRBAG HIGH. ) My observation is that maybe there is another connector after this one you showed on your video before the central airbag that is malfunctioning because current did not get to this point you displayed on your video because I changed the door airbag too.
@@nero73357 hi! you need to search for connector responsible for the door airbag. Try and trace the electrical wires which come from the door and go into the main electrical loom. You can also change the electrical connectors if you have possibility to do so with brand new ones. If you have changed the door airbag and put a new one in then you need to reset the crash sensor data. Which is a totally different problem.
@@nero73357 you need to find it. I really don't know where it is. Take the door card off, trace the electrical wires from the door airbag and see where it goes into the car.

Salut! Nu, urmareste videoul si vei observa ca pt stergerea erorrii este nevoie de o diagnoza care sa citeasca si sa stearga codul de eroare. Daca reparatia este facuta corect, dupa ce se sterge eroarea din diagnoza, nu o sa mai fie probleme.
@@emanuelmaxinan6073 da, dar numai daca eroarea ta vine de pe acelasi manunchi de fire. Ce model de w203 ai? Facelift sau non facelift? Daca e non facelift eroarea de SRS poate sa-ti vina de la airbag cortina stanga, airbag cortina dreapta, airbag din usa stanga sau din usa dreapta (ambele pe fata). Mai sunt W203-uri ceva mai echipate care au airbag-uri si pe usile din spate. Daca ai un cod de eroare pe diagnoza vei putea vedea in descriere de pe care airbag vine.
am aceiasi problema la un c kompressor din 2004 , am facut procedura doar la conectorul din pragul din stanga , am eroarea R12/20 , dupa ce am sters codul SRS si am pornit din nou - face din nou aceiasi problema, Am de asemenea un tacanit ce vine din zona bordului ca si cum ar fi un acuator sau compresor etc...care continua timp de 2 minute - chiar daca opresc motorul si scot cheia din contact,....Orice sugestie apreciez mult!
Despre eroarea de airbag îmi trebuie codul și descrierea exacta a erorii ca să te pot ajuta. Tot la scanare o sa iti dea un cod de eroare pt tacanitul din bord. E vorba de motorașul sau motorașele electrice care închid și deschid fluxul de aer de la aeroterma din habitaclu. Ca sa remediezi aceasta problema trebuie să dai jos tot bordul.
@@AlexAndreiZAR nu am alta eroare cand scanez ce ar fi legat de motorasul din bord precum spui (credeam ca sunetul are legatura cu airbagul) ...dar problema cu SRS-ul a venit simultan cu tacanitul din bord care dispare dupa 2 minute ( fie motorul pornit sau oprit- si tacanitul apare imediat ce pornesc masina - )

Hendy Rukman my logic would say it would be on opposite side. Basically to be sure you can do both sides. There are connectors on both sides. Then after you do it you just have to delete error with diagnostic tool.
Похоже, что с начала вам необходимо произвести диагностику прибором который способен читать банк с ошибками SRS!!! При помощи такого прибора можно попробовать стереть ошибку из банка и узнать в какой конкретно зоне именно в вашем случае, случилась данная ошибка. Я слышал истории, когда такая ошибка выпадала в следствии того, что автомобиль где-то хорошо был подмочен, но после того как его должным образом просушили, оставалось, опять таки - удалить ошибку из банка. На сколько я верно понял, в данном ролике причиной являлось физическое отсутствие контакта в штекере подушки левой двери и возможно кстати тоже - в следствии попадания некогда туда воды. Человек, срезал штекер, зачистил изоляцию, скрутил провода как было по цвету, пролудил оловом, одел 2 термоусадочные трубки. - Он устранил причину! Теперь ему останется подключить вышеупомянутый прибор, чтобы удалить ошибку из SRS банка.
