I'm an apprentice car mechanic and was working on the HV system of my 2014 Fortwo Coupe(replacing a wire where a mouse had chewed through it after the car has been standing for 6 months). and I was taking all the precautions! (HV disconnect, gloves, rubber boots, etcetera ) and when I plugged the HV Disconnect back in I get the message: HV System Workshop : so I took a bosch EsiTronicII and checked all the fault codes and went over it and they are all good and deleted. but I still have that dumb ass message in my dash. is there any way to get rid of the message without going to an MB dealer and having them use their pricey Star system?
