    Abstract: This paper introduced a type of temperature model whi ch was applied in the online diagnose.Described the model building approach and di agnose algorithm.This model deprived usable information from the engine control model(ECM).And it would operate synchronously with the engine.The model would de tect and isolate the failing of the coolant system.
