The self diagnosis and recovery method for doubling common bus resource and processor of a full electronic exchanger comprises: an initial state self diagnosis and recovery step(101-106) in which a self diagnosis test is executed for memory, data line and message input/output hardware by test set modes at an initial step, and if the test result is abnormal, the information of an error generation position is outputted to automatically recover the error state; a loading state self diagnosis and recovery step(110-125) in which self diagnosis test and recovery are executed for occupation possibility for doubled bus resource at the load state and as to whether the occupied bus is normal and is transferred to a normal loading state; and an one-line state self diagnosis and recovery step(130-148) in which self diagnosis test and recovery are executed for serious error generation during one-line program process at the one-line state, a normal operation of a periodic bus, a transmitting/receiving path of processor doubling information, and a periodical bus deviation.
