my 2003 e320 got 60,000 miles. the srs light is on. i have the obd2 diagnostic tool for mercedes. but my question comes to check for the srs codes it tells me to plug in the 38 pin map, i couldnt find the location to plug in the 38 pin map. or do i need a adaptor to convert the 38 pin map to obd2 ? I APPRECIATE ALL YOUR HELP!

 

I don't know the answer. I saw a 1/2 inch thick book specifically on OBD2 system at the parts store this weekend. Should have got it.
