I changed the 12 v battery in 2015 EV Smart Car and ignition key was on when I placed the positive cable to the battery. This caused many problem lights to come on and an error message stating "HV battery problem, take to shop" I live 80 miles from the nearest Smartcar shop and don't feel like that is necessary. I would like to cancel out the error message to see if it comes back on or not. I don't know how to cancel the error message. Do any of you?
