A method for diagnosing vehicles in an EOL production line is disclosed. According to the present invention, the method for diagnosing vehicles in an EOL production line allows an electronic control unit provided in a vehicle in the production line to receive, from an external scanning device, diagnosis condition information (e.g. input data for checking the driving performance of a vehicle) for executing a production line diagnosis mode of an end of line (EOL) process, enter a preliminary diagnosis mode before switching the production line diagnosis mode to an active state, determine whether to start the production line diagnosis mode and, if there is the possibility of damage to an engine due to the execution of the production line diagnosis mode during the execution of the production line diagnosis mode, based on the determination result, block the production line diagnosis mode, thereby even if coolant is not put into the vehicle or the right amount of coolant enough to cool heat generated by driving the engine is not put thereinto, due to the inexperience of the vehicle assembly work in the vehicle production line, efficiently blocking the production line diagnosis mode of the EOL process and, if the possibility of damage to an engine occurs due to a shortage of coolant even during the execution of the production line diagnosis mode in the EOL process, and blocking the execution of the production line diagnosis mode in the EOL process at the time when the possibility of damage to the engine occurs.
