Abstract
A method for diagnosing leakage of electronic parts and servicing guide of a driving state for a vehicle in a battery management system is provided. The method includes normally driving the vehicle or stopping the vehicle by cutting off a relay based on whether electronic parts broken due to insulation resistance breakdown are required for the driving of the vehicle. In addition, the method includes services a guide required for each broken electronic part about a driving state of the vehicle, by stepwise measuring insulation resistance of vehicle key on, engine starting, an operation of load parts such as a driving motor in the vehicle, an air conditioner, and a low-voltage DC-DC converter, and the like.
