Troubleshooting Mercedes Benz Cars


1. Look for the OBD port on the driver's side dash underneath the steering column.
2. Plug the OBD scan tool into this port. Put the key into the ignition and turn it to the 'II' position. This will turn on the electronics in the vehicle..
3. Wait for the scan tool to read the trouble codes. These codes will appear on the face of the scan tool.
4. Check the scan tool menu for the meaning of each code. Write down the problems with your Mercedes, based on these trouble codes, and bring the information to your mechanic or dealership. Or make the repairs yourself if you are able to.
