Diagnostic information synchronization method and device, electronic equipment and storage medium

The embodiment of the invention provides a diagnosis information synchronization method and device, electronic equipment and a storage medium, and belongs to the field of vehicle-mounted diagnos.The method comprises the steps that when an MCU core receives a type of fault notice, the sending type of a fault transmission structural body of the type of fault notice is set to be a first identifier and then written into a shared memory block, so that an SOC core is indicated to receive the fault transmission structural body; and after the SOC core reads the fault transfer structure written into the shared memory by the MCU core from the shared memory block, setting the sending type as a second identifier and then writing the fault transfer structure into the shared memory so as to synchronize the fault transfer structure to the SOC core, similarly, when the SOC core receives a second type of fault notification, writing the fault transfer structure into the shared memory in the same way so as to synchronize the fa
