The ECM Hardware number (HW) is an important parameter of ECM
BOSCH Motronic ME17.8.5. Each firmware (SW) is designed for ECM with a specific Hardware number.
DIUS 3 software allowed ECM programming only with firmware that was
designed for the same HW number as the programmable ECM.
Neglect of this restriction led to the failure of the ECM.
DIUS 4 software supports firmware programming for ECMs with a different HW
(changing the HW during process).
Currently, in BRP vehicles are used ECMs
BOSCH Motronic ME17.8.5 with Hardware numbers 666060–666067.
Depending on the HW numbers of ECM and Firmware,
reprogramming of ECM can be done in one or two passes.
ECM Reflash 1 pass is used in the following cases:
The HW numbers of ECM and Firmware are identical.
The HW numbers of ECM and Firmware are any of 666060–666062.ECM Reflash 1 pass
1.Plugin the MPI Interface in the USB port computer and it should now be green light on the adapter.
To check so all working you can start ”MiniMon”
on your desktop and check so the interface is communicating
2.Locate the Diagnostic Port on your Vechicle – and connect the diagnostic end of the interface MPI
3.Run DIUS 4.
4. Press the BRP button.
5. You will see the data of your connected MPI.
To read the electronic modules of connected vehicle, you must press the button IXXAT:
6. DIUS 4 will show the connected modules.
Here you can see the current HW number and Firmware number (BRP Assembly Number) 420666378.
In our example, we are using ECM with Hardware number 666062.
Open the ECM Firmware tab.
7.1. Select the Container.
The BRP DIUS Flasher 4.0 Stock and BRP DIUS Flasher 4.0 Tunes containers are currently available.
2. Select the Vehicle type, HW number and firmware (SW) you want to load into ECM.
In this example, we will use the firmware 420666373 designed for ECM with Hardware number 666062.
3. Click on the REFLASH button.
4. Confirm your decision by clicking on OK.
8. Reprogramming process in progress:
9. The reprogramming process will be completed when the Transfer Data Bytes counter reaches 100000.
After successful process completion, the status bar will change to Read INFO Complete:
10.Press F12 on your keyboard to refresh the ECM Firmware page.
The counter Used will show +1 more used firmware. This means that the firmware programming process is completed
successfully.
11. Open tab Selector.
Here you can see that the BRP Assembly Number has been changed from 420666378 to 420666373:
