If the conditions are satisfied at step 812, the processor code portion (e.g., first (μP) portion 630) may be installed within the processor, as indicated by step 816. If desired, code for at least one processor that does not exercise independent authority in updating its code can be installed at this step. For example, the third and fourth processors (e.g., the high power wireless communications circuitry 212 and the low power wireless communications circuitry 214, respectively), but not the second processor (e.g., safety processor 230) can be updated at this step. The second processor (e.g., safety processor 230) may independently decide when to update itself, and is not committed to being updated at a time commensurate with the software updating of any other processor. The installation process can include several steps, which are discussed in more detail in connection with
