The invention discloses a method for generating a substation detection message in an automobile CAN bus body control system, which is characterized in that: when the automobile CAN bus body control system works, a substation module, after detecting that the external electric quantity of an inputting lead pin changes, acquires a CAN message of the inputting lead pin which corresponds to the substation by searching in a pre-established mapping table and sends the CAN message to a main station module. In the invention, when the automobile CAN bus body control system works, the substation module can generate the substation detection message in real time and send the substation detection message to the main station module after detecting that the external electric quantity of the inputting leadpin changes.
