Hello Forum need help. I have an 05 SL500. The batteries are fully charged. I turn the key all lights on the dashboard. I borrowed an scanner from an friend an AUTOLOGIC. Scanned the vehicle for fault codes there were none. I checked all the fuses to be good. I checked the starter relay and tested it and when manually it turned the starter but car will not start. With the computer it sees the keys and bank number. It see when you turn the key. It seems that the car is in park. What are these two fuses that are under the dashboard and what do they do? Thanks for any help.
