| description | It is hereby disclosed a method of writing software objects into a rewritable nonvolatile memory (245) of an electronic control unit (215) of an internal combustion engine (100), wherein the method comprises: receiving an access request from a memory writing device (300), generating a seed code, transmitting the seed code to the memory writing device (300), generating a first key code on the basis of the seed code and a first identification code, generating a second key code on the basis of the seed code and a second identification code, receiving a reference key code from the memory writing device (300), comparing the reference key code with the first key code and/or with the second key code, and enabling the memory writing device (300) to write software objects into the rewritable nonvolatile memory (245), if the reference key code corresponds to the first key code or to the second key code. |
