What scanner are you using and where are you plugged into for scanning?No codes to report. SRS light dors goes out sometimes but mostly on. Suspecting Transmission harness as it has not been replaced yet. Speedo is on and off now too. Mostly off. No check Engine Light but the Radiator light is on since I bought it and it has just had the trans rebuild and rad replaced.
Not sure if your scanner will read thru the 38pin connector (with a proper 16pin to 38pin cable adapter). I highly doubt it will work. You need to be able to scan the other codes (which Im pretty sure are stored) thru the 38pin (that you cannot read thru the 16pin. As well, you will need to be able to erase the SRS codes your getting (and any others you read and find) thru the 38pin) OR head to an proper indie shop or borrow a decent 38pin scanner to obtain some readings thru that port. No way around this with your present scanner, imo.Yes it has the 38 pin in the compartment under the hood and the standard ODB connector by the steering column.

The scanner does live data as well as atored data. It have 3 layers of screen many of which have sub menus. What doesn’t generate a code? Disconnected the MAF sensor and it stalled.
And you read the scanner from the 38pin connector already?I don't have any trouble codes but I just realized I do have a Radiator trouble light on. I didn't think much of it because the last owner had the tranny rebuilt and the rad replaced because water got into the tranny lines and rusted the tranny. Trans works good and run cool but that light is on all the time. I read it could be fans.
Does the adaptor from the standard OBD II 16 to 38 pin work? I would expect an OBD II wouldn't have transmission codes.And you read the scanner from the 38pin connector already?
Transmission codes need to be read from the 38 pin.
When a tranny light comes on, it needs to be investigated (ie. codes to be read) and then it has to be erased at the 38 pin connector. The CEL for the trans do not just disappear on their own after an issue is addressed.
All adaptors that connect to your std 16 to the 38 pin (under the hood) are not created equal.Does the adaptor from the standard OBD II 16 to 38 pin work? I would expect an OBD II wouldn't have transmission codes.
thanks you khomer2All adaptors that connect to your std 16 to the 38 pin (under the hood) are not created equal.
Also, some (good) scanners cannot read the tranny codes from the 38pin for these older MBs.
I'm not sure about your scanner and you'd have to check even if the supplier/company even sells an adequate 38pin adapter for your scanner and that will be able to read the trans codes on your w202.
We use both an Autel md802 and foxwell nt644 for all our vehicles (neighbors included )
C3 - and there is plenty of discussion/assistance for those that use this. Read up on it to familiarize yourself with it, if you havent done so.thanks you khomer2
The scanner was Amazon's top seller and runs the ISO9141-2 software.
I have been looking at scanners specifically for MB. iCarsoft Genuine Mercedes Benz I980, MB Star C3, for an older 1994 Benz with likely transmission codes what would you recommend out of the two you listed? I was starting to think about throwing a Purge Valve and Crank Sensor at it. No code on the Purge Valve so it's sound electrically so I am buying a hand vacuum pump to test it. Crank Sensor, I was going to pull the cable and see if it generated a Check Engine.
