If non-default values for the
“ECU Instance Number”
or
“ECU Address”
are used, they will be
mirrored during a setpoint file flashing, and will only take effect once the entire file has been
downloaded to the unit. After the setpoint flashing is complete, the unit will claim the new address
and/or re-claim the address with the new NAME. If these setpoints are changing, it is recommended
to close and re-open the CAN connection on EA after the file is loaded so that only the new NAME
and address are showing in the J1939 CAN Network ECU list.
