VVDI Prog Read Opel Corsa-D RENESAS V850 BCM

How-to: calculate PIN code from Opel Corsa-D BCM dump. Before calculating, you need use xhorse vvdi prog programmer to read out dump file from Opel Corsa-D BCM.

Procedures:

Step 1: Read dump from BCM

Remove BCM and disassemble the cover to take PCB out.

Solder wires on PCB according to the wiring diagram. In this example, we take VVDI Programmer as example,the diagram show on the software.

In VVDI-Prog software select “2-MCU”–>”RENESAS-V850”–>”D70F3379”

Select “P-FLASH” and click “Read” button

It will take several minutes to read out P-FLASH data from BCM

Save the P-FLASH data

Then open it with a editor, like HEX Workshop Editor

Step 2: Calculate PIN Code from Dump

Now you can calculate PIN code from BCM P-FLASH dump:

Open dump from FLASH and read value from address 3FD0 3FD1 3FD2

In this example,I have value F8 9A 5D

Double value from address 3FD1

Now we get value:F8 9A 9A 5D

Open dump from EPROM and read value from address 0010 to 0013

Save value,i have in EEPROM dump to address 0050 to 0053

In my example i have CC A8 A8 65

Now open HEX calculator and make value FLASH XOR value EPROM

In my case,F89A9A5D XOR CCA8A865=34323238

Ignore 3 and find value 4228

Now read reverse the value and it is PIN code: 8224!
