4. Upon reset, the ECU will no longer show up on the J1939 network as an AX141100 but rather as
J1939 Bootloader #1
.
Note that the bootloader is NOT Arbitrary Address Capable. This means that if you want to have
multiple bootloaders running simultaneously (not recommended) you would have to manually
change the address for each one before activating the next, or there will be address conflicts. And
only one ECU would show up as the bootloader. Once the ‘active’ bootloader returns to regular
functionality, the other ECU(s) would have to be power cycled to re-activate the bootloader feature.
