How to Renew BMW FEM BDC by Auro OtoSys IM600

This manual introduces how to conduct BMW FEM/BDC ECU Renew on Auro OtoSys IM100/IM600 key programmer.

 

 

Two options are available when accessing FEM/BDC Renew:

 Copy Data Update When the immobilizer information of the vehicle can be read

from the original FEM/BDC module, perform this function to read the information

and write it into the replacing FEM/BDC module.

 Calculate Data Update : When the immobilizer information of the vehicle cannot

be read from the original FEM/BDC module, perform this function to generate

the information via the input VIN code, vehicle frequency and engine ISN code

and then write it into the replacing FEM/BDC module.

 

NOTE

Illustrations used in this manual are samples, and the actual testing screens may vary by

vehicle. Observe the menu titles and on-screen instructions to make correct selections

and operations.

 

FEM/BDC Renew via Copy Data Update

Preparation

1. Attention: If there’s an ELV in the vehicle, the ELV may not be unlocked after

performing FEM/BDC Renew. You’ll need to solve the locked problem yourself, so

please start the operation with careful consideration.

2. To perform the Copy Data Update function, a working key or the engine ISN code is

needed.

3. The hardware version of the original and replacing modules can only vary slightly.

Otherwise, the DTCs of the vehicle may not be cleared.

4. Remove the FEM/BDC module from the vehicle.

Removing the FEM/BDC Module 
The FEM/BDC module is located at the A-pillar of the front passenger side.
 Procedures to remove the FEM/BDC module from the vehicle:
1). Unclip the front door sill cover strip at the passenger side.
2). Remove the bottom right instrument trim panel and disconnect plug connections behind it.
3). Remove the side trim panel at the passenger side.
4). Remove the cover at the lower part of the module.
5). Unlock the positive battery cable connector.
6). Disconnect the plug connections to the module.
7). Release the bolt from the module.

8). Remove the module from the vehicle.

5. Conduct ECU preprocessing on the replacing (used) module and the original module

to make them able to learn keys. No ECU preprocessing is needed for the replacing

module if it is a brand new one.

6. Prepare a blank key.


Procedures

1. Connect the OtoFlash to the original FEM/BDC module via the included main cable.

2. Connect the OtoFlash to the IM600 tablet via USB connection.

3. Turn on the IM600 tablet and tap OtoSys > IMMO. A vehicle menu displays and a

disclaimer prompts up. Tap Accept to continue
