Car did not crank and radiator fan full blasted

I have a 2006 SLK280 sitting for years due to electrical problems. I decided to fix it today because a random cop decided to drive around my neighborhood to find abandoned car.

I bought a new battery and after the replacement, the car did not crank and the radiator fan full blasted. Also, I cannot scan the car with my obd2 scanner(bluetooth scanner).

It has a lot of codes, mostly battery related(see pics)

what should i do?








I will push the car onto my driveway tonight then continue fix it.

Alot of meaningless codes can pop with low voltage battery. Unplug the fan....Hook Up your new battery....and erase all codes. After that whatever codes appear might be more relevant.

I’d start looking near the fan.
