Abstract
A method and system for detecting fusion of a relay are provided to more accurately diagnose fusion of a relay by adjusting relay OFF order when a vehicle engine is turned off using data regarding whether fusion of a relay was detected when the vehicle engine was turned on. The method includes detecting whether first and second relays have been fused when a vehicle engine was turned on and adjusting OFF order of the first and second relays when the vehicle engine is turned off based on whether the first and second relays have been fused.
