ECU Data Flow

Figure 6-53 shows the ECU control data flow when ECU replacement is required. When an ECU is ordered
from the factory, the ECU control data is selected according to the engine identification information such as
the engine serial number and pump serial number. Then an ECU is provided directly by the factory. The data
is stored in the production system network.
