Hello friends! I had to remove a seat out of a 2020 DB11 for a repair. Since seat was removed it triggered the airbag light and I need to reset it. I only see one OBD port in this car and it only gives me engine codes. Is there a second OBD that does all the body codes like the older Astons? If so, any guidance on its location? Thanks!!!!!!

 

Hi @eroc0808,

The OBD II port is the one source for all fault codes (B-codes, C-codes, P-codes, and U-codes) on this MY DB11. Problem is the tool, especially if it is a V12. A simple OBDII scan tool will only retrieve P-codes. You need a deeper scan tool to extract any other codes, or to reset certain functions such as SRS. Unfortunately, I cannot say there are any tools I've run across that can work on this system.

If you have the AMG V8, there is a possible better chance using MB compatible deep scan tools (maybe). Since I have the V12 in my DB11, I am "on the hunt" for scan tools and yet to find one, but also cannot experiment with some tools I have that work on the AMG platform.

Sorry this is probably not much help for you....

 

Thank you for the reply! I was afraid of that. I'm using the AUTEL MAXISYS ELITE that works on anything but this so I suppose its not compatible at the moment. I do believe this car is a V8, not near car at moment though, so maybe I'll run through a few Benz settings and see. Oh well. Thanks again.

 

Yes, one of my favorite tools is an Autel Mx808. I used it extensively on my AMG GTS. it read every module and I could reset many functions.

If I had the V8 I would try using the MB settings but NOT try reading the VIN. Just go directly to diagnosis.

Here is a typical printout of a deep scan on the GTS

 

BWings you're the best!!!! I went in under the Mercedes protocol and swept everything. Air bag light is now extinguished. Thank you for the tip.

 

Glad it worked and the info you just provided is invaluable insight for me.

Thank you!
