Please download the Mercedes-Benz fault code manual using the bellow link:

The MB Fault Code Manual covers 1988-1997 Analog & 1993-2000 Digital Codes.
There are basically 3 methods to diagnose a pre 1998 Mercedes-Benz:
1. MB Star
2. OBDII Adapter
3. Blink Method
in this video I am going to focus on the third method as the most simple and available method.

The easiest and most available method of diagnosing a pre 2000 mercedes and it is free too, for me it was the only way to clear fault codes on my convertible top module. Please download the fault code PDF, which is in the description. Thank you for watching and subscribing.
I am making the code reader. What is the clear plastic junction piece called and where can I find one?
@brandonfowler6013 TBH I am not sure, just use what is available, that's just decorative:)
@@brandonfowler6013 thats a domino connector.
great service. very educative .Thank you regards
Thanks mate
thank you for the video. I've a china-sd too. Same Problem for example with W210. With the advice of your video I can help myself a little bit more. ☝
Thank you Oliver, I learnt this the hard way...
Thank you for posting this video! I’m in the same boat with my 96 SL320. The foxwell and C3 could not communicate with my 38-pin connector. Going to try this today and see if it works.
👍 👌
Thank you very much for the video and the link. I hope it help me to find a combustion failure...
Thanks mate, fingers crossed 🤞
Thank you
You are welcome
Thanks for your videos, always very informative and because you're based in Australia is even better. I have just bought a '96 Sl500 r129. As this video was done about 9 mths ago have you searched anymore for an OBD scanner that will diagnose the r129 fully including Roof and Suspension ? Thanks George
Thanks mate, the situation for 96 year might be better and you might be able to diagnose using a OBD2 Scanner. I am not 100% sure though on the brand you should use.
can I simply run 2 wires from 12V DC LED light and from the negative wire a switch wire? no fancy block as yours😂. I've seen even more sophisticated self made OBD readers. I don't want to over do it. is the block important? thank you very much for all your helpful videos!
Hello, there is no fancy thing as long as you keep your wires safe and insulated. Just follow the diagram and good luck 👍
I like your video and your explain but for example if i need to check the electronic transmission 722.6 ? If there is fuolt ! How many times will light?? Please answer..
great service. very educative .Thank you regards
Thanks bro, It depends on the fault, you need to count the numbers then based on the number find the fault.
First of all, thank you for this video! I made a code reader to diagnose my ASR light and limp mode for my 92 500sl 16 pin connector. I'm in the US by the way. I tested the "Electronic Accelerator / Cruise Control / Idle Speed Control (EA/CC/ISC) w/ASR". The book says it's
"Closed throttle recognition signal to engine control module (HFM-SFI or Left LH-SFI) Fuel safety shut-off to engine control module (HFM-SFI or left or right LH-SFI)". Can you point me in the right direction? Thank you again!
Update, I reset the code and then went for about a 5 mile drive. The ASR light came back on but not limp mode.
I would do a google on this...
Better than the limp mode 😉
HI. Is it possible to reset the SRS light on a 1997 Mercedes W210TD. Thanks
I think it is possible with this method.
I can’t pull the codes on this W202. I have a LED tool, it works on my w124 but can’t get it to flash any codes back
Even form socket number 8?
@@BenzAddiction I can see which pins have connections. I tried them all. I get the LED on with the button, but no flashing? Many thanks for any advice
would this work on a 2001 CLK w208? I'm european so my car does not have OBDII onyl the 38 pin
Should work
@@BenzAddiction Thanks!!! I'll let you know so you can add the info to the description ;-)
@@BenzAddiction Where did u buy that plastic thing that holds the wires and how is it called? (sorry i'm neither english neither expert on circuits)
@@st.dardust_garage I think that is called a wire terminal. But you do not need to have that simply use duct tape to secure cables.
Thank you very much
So I made the testing circuit, but when I press the button, nothing happens. If i reverse the circuit but not connect 16 , i have led light. So I have 12 Volts on all test points but when I push it to ground with the button, nothing happens afterwards.. Why is this?
I checked my wiring again, diode was wrong way around, but I still have trouble getting it to blink on error codes, the led lights when I press the button now. But no blinks after i have pressed it for 3-4 sec.
Just check your circuit logically again an refer to the diagram shown in the video, soon I am going to use the same test light on a W124, good luck.
You have to check each pin individually? How do you decipher what the code means?
All this data for codes are available online if you google it. Positive and negative is always fixed, the data cable (green) is for different modules.
Thank you. If I’m having starting issues, what pins would you recommend checking? The car was running great and then it stalled and won’t start. Just replaced fuel pump. No change.
@@danludwig3679 These modules are not very sophisticated, I would start 1. Checking fuel pressure 2. Pull a plug wire and check for ignition while cranking. If it is fuel related, fuse and pump relay to be checked. Ignition related: might be coil...
@@BenzAddiction thanks again man 👍🏼. Fuel pressure is good. I will check for spark.
Actually 96 was the year ODB2 was introduced.....
In some countries...
1996 USA Mexico and Canada
Boa noite. Para apagar avaria do Air bag luz srs, consigo fazer dessa forma ? Retirei o volante com a chave ligada
The best thing to do is not buy a Mercedes, otherwise you are just looking for trouble
Yeah, we love these dramas :)
