- Use other devices (I.E Xhorse VVDI Prog) to read out the D-Flash and EEE data in the KVM;
- Use Mart tool to generate new key and data;
- Finally write back to KVM.
Take Range Rover for example:
- read out the D-Flash and EEE data in the KVM
Dismantle the FK72 box from the Range Rover.
Open VVDI Pro to follow the wiring diagram to remove the components (6 in total) and then welding wire.
Plug the MC9S12 Reflash cable to VVDI PRO and start to read out the D-Flash and EEE data in the KVM.
Reading with VVDI Pro.
Land Rover… RFA encrypted (MC9S12XEQ384)
Later I will encrypt the “Chip unencrypted (FE)”.
First read out D-Flash and save, then EEPROM and save.
Load KVM_EEPROM and Load KVM_Dflash.
Select “Key3” (Unused)
Put the key on the Mart tool.
Select “Detect” and read out the Key ID.
- Use Mart tool to generate new key and data.
Select ” Generate dealer key”.
Save the key info for two times.
- Finally write the data back to KVM.
The data is processed successfully, please write back the data to the KVM.
File, key 3…… Write successfully.
Write the key data, maybe you need to do it for one more time.
Start to encrypt the FE and complete.
Use the air gun to blow off the wires.
Weld back the chip “GND-C”. PS: this chip is easily broken, please back up more than one piece for replacement.
Install the chip board into the FK72 box.
Plug the FK72 box back to the Range Rover car.
Press the key to start the car.
The car can starts.
