Automotive ECU Read/Write Operation
As a multi-functional programmer device, the Multi-PROG device supports
reading, writing and cloning ECU for some common brands of automobiles,
which can be used for automotive ECU repair and replacement, etc.
Usually, the ECU of each brand of automobile is provided by third-party manufacturers,
and the common automobile ECU manufacturers are Bosch, Siemens, Continental,
Marelli and Delphi, etc. The Multi-PROG programmer supports the reading, writing and
cloning ECU of common brands such as Bosch and other manufacturers.
It supports BMW MSV90, MSV80 and other series ECU reading, writing and cloning,
supports BMW B48, B58 series ECU reading ISN, supports Mercedes-Benz SIM271
series ECU reading and writing, supports VW Bosch ECU MED17 series reading, writing
and cloning.
Operation steps:
1 Select the module type‘ECU/BMW/1-Series’ menu, and select MSV90 as shown in .
Figure 8.2.1.
2. Connect according to the wiring diagram shown in the software. Attention: choose the
appropriate ECU cable plus, the device comes with 8 different kinds of ECU cable plus.
3 . If the ISN is required, the ISN will be displayed in the device software after reading the
EEPROM. If the ECU needs to be cloned, the EEPROM and FLASH need to be read and
saved, and the saved data should be written to the ECU to be replaced.
Operation steps:
1. Select the module type ‘ECU/Mercedes/C-class’, as shown in Figure 8.3.1.
2. Connect according to the wiring diagram shown in the software. Attention:
choose the appropriate ECU cable plus, the device comes with 8 different kinds of
ECU cable plus.
3. If the ECU needs to be cloned, the EEPROM and FLASH need to be read and saved,
and the saved data should be written to the ECU to be replaced.
