I.ECU Data Reading/Writing
1. Obtain the related ECU.
(1) Method 1: Obtain the desired ECU type through brand > model > engine > ECU in turn, as shown in Figure 3.

(2) Method 2: Query the desired ECU by entering a value in the search box. The search categories includeBosch number and Search, as shown in Figure 4. For example, search for the MED17.5.25 engine by Search, as shown in Figure 5.


2. Click [Direct Connection Diagram] to obtain the ECU connection diagram, as shown in Figure 6.

3. Connection: Connect the ECU and PCBOX according to the information provided in the connection diagram. The physical connection diagram of MED17.5.25 (using the BENCH mode line) is shown in Figure 7, and the physical connection diagram using the gearbox adapter is shown in Figure 8.


4. Read the chip ID, as shown in Figure 9.

5. Back up the EEPROM data and save it, as shown in Figure 10 (the figure shows the save page of the read data).

6. Back up the FLASH data and save it, as shown in Figure 11 (the figure shows the process of reading FLASH data).

7. Restore EEPROM/FLASH data, as shown in Figure 12 (the figure shows the file selection page).

II. Data Processing
1. Click the [Data Processing] button on the main page, as shown in Figure 13, and select [IMMO Off and File Verification] ([DTC Shield] is not currently supported), as shown in Figure 14.


2. File verification and IMMO off (process: select file > connect network to obtain > save file), as shown in Figure 15.
