Replace BMW FEM BDC Module with Autel IM608

 In the Autel training tutorial, we are doing a BMW FRM/BDC Module Replacement with the Autel MaxiIM IM608 or the IM508 with XP400.

 

IM608 FEM BDC Module Replacement Guide:

• Read EEPROM
• Modify Data
• Backup Coding
• Renew FEM
• Replace FEM module

1). Read EEPROM

Remove the old module from the vehicle
Take a photo to record the correct fuse sequence
Take out the fuse with the needle nose pliers
Take out the module circuit board

Remove the EEPROM chip from the board

Put the chip into the XP400 Programmer as shown
Connect XP400 to your IM608
Click on IMMO to find BMW and Enter System Selection- Immobilizer- EEPROM- FEM/BDC Immobilizer-EEPROM Operation-M95256

Read and Save EEPROM

2). Modify Data

Click the Modify Data function and select the file just saved before

The EEPROM data file has been modified successfully, save new data.
Save the modified text as a new file

Write the modified file back to the chip
Write modified back to chip success

Solder the chip back to the board
Install the fuse back in the correct order
Put the old module back into the vehicle
Under the FEM/BDC immobilizer system menu, select vehicle information to read the original car information

Take a screenshot for future reference

3). Backup Coding

Go to Coding operation- execute the Backup coding
Read backup coding success
Save the backed up coding data as a new file

Select Programming operation, then execute ECU Preprocessing function
Ensure you have stable WiFi network connected

The programming is about to start, make sure the supply voltage exceeds 13V and it is stable

Wait until programming successful

Remove FEM module and take the chip out of the module again and put it into the XP400 programmer
Re-enter the previous EEPROM operation menu
Select Write Operation- Select initial raw EEPROM data file
Take out the chip from the XP400 and solder it back into the old module circuit board

 

4). Renew FEM/BDC
Put the old module back into the vehicle

In the mode interface, enter the ECU Renew menu, select the anti-theft controller unit- select FEM/BDC renew
Select Copy Data update

Carefully reading the operation instructions

then choose to backup FAFP data and save it as a file

Enter Read IMMO Data function, select the menu according to the actual situation of the vehicle
(Vehilce with or without ELV, Do you have a working key)
Here we select vehicle without ELV and does not have a working key
If there is no original car key, select NO to read the IMMO data and confirm and save

If you have the original car key, choose Yes to read the Immo data.

and stick the original car key to the emergency induction area as Autel IM608 directed, confirm and save after reading

Read password successfully
Save data

5). Replace FEM Module

Take out the old module and install the new module
the new module needs to be brand new, otherwise ECU preprocessing needs to be performed.
Enter the COPY Data update function, execute Write FAFP and write immobilizer data function

write in the old module data previously obtained

Perform repair coding

Perform key learning with im608
Read password and write key

Done.
