The invention provides a fault processing method, device and apparatus and an automobile, and relates to the technical field of automobiles. The fault processing method comprises the following steps that: a first E2E message is sent to a first slave node, wherein the first E2E message comprises a CRC signal and a COUNTER signal; a second E2E message sent by the first slave node according to the first E2E message is received, wherein the second E2E message is used for indicating whether CRC signal verification of the first E2E message fails or not and/or whether the COUNTER signal of the first E2E message is abnormal or not; according to the second E2E message, whether a communication fault exists in the first slave node or not is determined, when the communication fault exists, a verification fault code and freezing frame information are stored, and the freezing frame is used for indicating the first slave node and LIN bus communication fault information detected by the first slave node. And the slave nodes d
