How to Repair the BMW FRM3 Module Using Launch X431 IMMO Plus and X-Prog3

Jan8

In this guide, we’ll walk you through the process of repairing the BMW FRM3 module (footwell module) using the Launch X431 IMMO Plus. This tool now supports one-click repair for FRM modules, including the FRM3R module (9S12XEQ384 3M25J) used in BMW E87, E92, and E93 models.

Tools Required:

Launch X431 IMMO Plus
X-Prog3 Programmer
Soldering equipment
Vehicle with a faulty FRM3 module

Step 1: Prepare the Connections

Ensure all your tools are connected properly:

Solder the cable to the FRM3 module.
Connect the cable to the X-Prog3 programmer, and then to the Launch X431 IMMO Plus.

Step 2: Read the Chip ID

Once the connections are set up, power on the system:

Select “Read Chip ID” on the Launch X431 IMMO Plus.
The ID should read successfully, confirming the connection is correct.

Step 3: Check the EEPROM Data

The FRM3 module often loses EEPROM data due to low or insufficient battery voltage. Follow these steps:

Navigate to the “Backup EEPROM Data” option.
You’ll notice the partition shows as zero, indicating the EEPROM is empty and corrupted.

Step 4: Repair the EEPROM

Now it’s time to repair the corrupted EEPROM data:

Click on the “Repair” function in the Launch X431 IMMO Plus.
The tool will read the flash data and create a new EEPROM file automatically.

Step 5: Confirm the Repair

Once the repair is completed:

Check the EEPROM data again. You should now see valid data populated in the EEPROM section.
The FRM3 module is now repaired and should function correctly.

Conclusion

With the repair process complete, your BMW FRM3 module is now restored and operational. Using the Launch X431 IMMO Plus and X-Prog3 programmer, you’ve successfully repaired the module with minimal effort.

How to add smart keys to Volvo XC40 2018- 2021 with Launch X431 IMMO Elite/IMMO Plus?

Jun30

To add smart keys to Volvo XC40 2018-2021 using Launch X431 IMMO Elite/IMMO Plus, you can follow the simple steps outlined in the “IMMO Prog” function. The entire process takes approximately 3 minutes.

First, select the Volvo option in the menu, and then choose the newest version V10.03. From there, navigate to the Anti-Theft Key Matching section and select XC40 as the specific model for key matching. Make sure you choose the correct year range, which is 2018-2021.

Before proceeding, it is recommended to check the Volvo/Lynkco anti-theft operation guide provided by Launch X431 IMMO Elite/IMMO Plus. You will find an operation introduction and a wiring diagram that you can refer to throughout the process.

To add a key, you will need to remove the CEM (Central Electronic Module) module from the vehicle. Follow the provided instructions carefully to ensure a proper and safe operation.

After removing the CEM module, you need to connect the Launch X–Prog3 key programmer to the module using the MCU V1 and MCU cable V1, following the provided wiring diagram.

Once the connection is established, you can start reading the CEM security data and adding the smart key. Select the “Read CEM security data (disassembling and reading)” option and pay attention to the prompts on the screen.

Make sure to save the vehicle immobilizer data after reading it successfully. This step is crucial for the key matching process.

Next, select the “Smart keys added” option and follow the prompts on the screen. Turn the START knob to the right once and release it, and load the CEM security data that was just read.

To complete the key matching process, place the smart key to be matched in the designated sensing area, usually marked with a key symbol on the cup holder. Ensure that there are no other keys inside the vehicle during this step.

If everything is done correctly, you will receive a confirmation message stating that the key matching was successful.

In addition to Volvo XC40, Launch X431 IMMO Plus/IMMO Elite is also capable of successfully matching anti-theft keys for Volvo S40 2004-2012.

Launch X431 IMMO Plus vs IMMO Elite vs X431 V+ vs PAD VII

Jun9

Launch X431 Xprog3 with GIII is used to program Benz/BMW/VAG/Porsche keys and clone or replace ECU/TCU modules.What’s the difference among Launch X431 IMMO Plus,IMMO Elite,X431V+ and X431 PAD VII with Xprog3 ?

In sum:
IMMO Plus has the same key programming and ECU/TCU clone functions as IMMO Elite.The difference between these two is that IMMO Elite has basic diagnostics but IMMO Plus has full diagnostics
IMMO tablets support newer vehicle immo programming,i.e Volvo pre-2022,Toyota pre-2022,X431 V+ and PAD VII do not.
PAD VII supports online programming, others do not.
To clone or replace ECU or gearbox TCU with X-prog3,your tablet should have the ability to connect via USB.Lanuch X431 V+ only connects via Bluetooth, so X431V+ with GIII can not clone ECU/TCU.
