This guide provides step-by-step instructions on using the Xhorse AO.D BCM2 adapter to read a vehicle's DFLASH and PFLASH memory and calculate immobilizer data. The new version of the adapter supports all BCM2 series, including 03xx, 04xx, 05xx, 06xx, 07xx, and 08xx.
While this adapter is compatible with both the Multi Prog and Key Tool Plus, this article will use the Key Tool Plus as an example.
Step 1: Hardware Connection
1. Identify the correct adapter for your specific Audi BCM2 module. There are two adapters (Adapter A and Adapter B) for different modules.
2. Carefully check that the adapter pins align correctly with the module. Ensure the FLMD, GND, and VRCG pins are in the correct positions. Refer to the wiring diagram and select the appropriate adapter.
3. This demonstration uses Adapter A. Align the pin positions and connect the adapter to the BCM2 module.
4. Flip and snap the two side buttons on the adapter to lock it securely onto the module.
5. Use the Key Tool Plus Adapter Cable to connect the assembled unit (BCM2 module + adapter) to your Key Tool Plus device.
Step 2: Software Navigation & Reading Data
1. On your Key Tool Plus, navigate to the following menu path:
Immo Programming >> Audi >> Select by type >> Fifth Immobilizer System >> Start programming
2. Select "Read BCM2 Data".
Tip: The new adapter uses a different menu entry. If you are using an old version adapter, you would need to enter the "Old Adapter" menu.
3. For the new version adapter, choose "Programmer Read (New Adapter)".
Step 3: Reading DFLASH and PFLASH
A. Read DFLASH
Select the chip "D70F3381_3634".
Choose "D-FLASH".
You can view the wiring diagram for reference on the screen. Click "Read" to read the DFLASH data.
Tip: Ensure the adapter and chip are properly connected.
The message "Read successfully" will appear when the task is completed.
B. Read PFLASH
Select the chip "D70F3381_3634" again.
This time, choose "P-FLASH".
Click "Read" to read the PFLASH data.
Step 4: Calculating Immobilizer Data
1. After successfully reading both memory sections, return to the Fifth Immobilizer System main interface.
2. Select "Load D/PFLASH to obtain immo data".
Tip: This operation will automatically load both the P-FLASH and D-FLASH files in sequence.
3. Click "OK" to start the process.
4. Once the data is successfully read, click "OK" again to save it.
5. After the save is complete, you can proceed with functions like generating a dealer key or performing key learning.
