Diagnose Pre-1998 Mercedes for Free & Easily(8-16-38 Sockets)

[@BenzAddiction]

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?

[@BenzAddiction]

@brandonfowler6013 TBH I am not sure, just use what is available, that's just decorative:)

Hello World Blink. A1 in three weeks of research and sharing. Thank you ! Went down the rabbit whole with Jaguar electronics..Now it's Mercedes turn. Read 1 pair behind the audio head unit so I got my Krone punch down tool out. Now we talking connecting a light globe for the vehicle to make it purr and Ohm. The path of least resistance, keep it simple, bring back analogue 🙂 Oils are not just oils.

[@BenzAddiction]

You are welcome 😊

[@Mrphantom1988]

Thank you! I copied your blink system. It lights on when I hold it for 3 seconds, but I am getting no blink after that at all. That goes for all pins, same thing

[@BenzAddiction]

That's weird 😕

[@Mrphantom1988]

@@BenzAddiction Rick's pdf file for error code says, no blink or 1 blink is no error but Mercedes USA pdf file doesn't say anything about no blink. Any thoughts?

[@MohammedAldawsari7]

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!

[@BenzAddiction]

Hello, there is no fancy thing as long as you keep your wires safe and insulated. Just follow the diagram and good luck 👍

great service. very educative .Thank you regards

Thanks mate

[@raymondr7769]

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.

[@BenzAddiction]

👍 👌

HI. Is it possible to reset the SRS light on a 1997 Mercedes W210TD. Thanks

[@BenzAddiction]

I think it is possible with this method.

[@RuudyL]

The best thing to do is not buy a Mercedes, otherwise you are just looking for trouble

[@BenzAddiction]

Yeah, we love these dramas :)

[@chrisforrest7034]

Actually 96 was the year ODB2 was introduced.....

[@BenzAddiction]

Thanks mate, fingers crossed 🤞

[@salehalsabahi3484]

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

[@BenzAddiction]

Thanks bro, It depends on the fault, you need to count the numbers then based on the number find the fault.

[@kendallmullenix5694]

Any update on this? Trying to figure out how to reset codes for my TCM. I replaced the conductor plate twice now but I’m not convinced the code has been cleared properly using the OBD2 port. I’ve read I have to use the 38pin port to clear it properly.

[@brandonfowler6013]

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!

[@brandonfowler6013]

Update, I reset the code and then went for about a 5 mile drive. The ASR light came back on but not limp mode.

[@BenzAddiction]

I would do a google on this...

[@BenzAddiction]

Better than the limp mode 😉

[@petter7252]

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?

[@petter7252]

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.

[@BenzAddiction]

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.

@@petter7252 Hi Petter, yeah, same here, my car is a R129 1999 but still has 38-pin connector, I was wondering if it has a different diagnostic system. Thanks for your attention, if I find something I will keep you posted, maybe @BenzAddiction can help us meanwhile.

[@George-f8m]

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

[@BenzAddiction]

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.

[@bernardwarr4187]

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

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 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)

[@BenzAddiction]

@@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.

[@st.dardust_garage]

Thank you very much

[@petartodorov2714]

Thank you

[@BenzAddiction]

You are welcome

[@danludwig3679]

You have to check each pin individually? How do you decipher what the code means?

[@BenzAddiction]

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.

[@danludwig3679]

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.

[@BenzAddiction]
