1. A communication error diagnosis apparatus for a vehicle, the communication error diagnosis apparatus comprising:
a processor configured to transmit a request message including diagnostic identifiers for diagnosing a plurality of controllers that perform vehicle functions and sequence identifiers of the controllers to the controllers depending on a sequence to receive response messages, and configured to analyze a low voltage differential signaling (LVDS) communication errors between the plurality of controllers based on the response messages received from the controllers; and
a storage configured to store data and algorithms driven by the processor,
wherein the processor is further configured to transmit a request message for requesting setting of a parameter for performing diagnosis of a first controller performing a first function of the vehicle among the controllers to the first controller, which is a master, the first controller configured to set the parameter and to release the setting of the parameter after performing diagnosis.
