How to repair FRM Module by CG100/CG100X?

CG100 and CG100X are excellent tools for repairing BMW FRM modules. While other programmers like VVDI Prog can read and write data, CG100 is specifically designed to repair the module.

Here’s a step-by-step guide:

Open the FRM module and remove the circuit board.

Use a special FRM clip adapter to connect the FRM module to the CG100 programmer.

Alternatively, you can use a CG BMW FRM Solder-free Adapter (recommended) or solder wires manually.

Connect the FRM module to the CG100 using the BDM4 adapter.

In the software, navigate to:

BCM>> BMW>> FRM>> E Series>> 9S12XEQ384 (3M25J)

Confirm the connection and press Start to read the data.

Connect a reliable power supply.

Ensure the voltage remains stable and does not drop.

Successfully read the chip’s D-Flash data.

Save and Repair

Turn off the power supply after reading.

Save the data file when prompted.

The CG100 will ask if you want to repair the FRM module—press “Yes”.

The repair process will begin automatically.

Wait for the process to complete. Do not disconnect during the repair.

Write the repaired EEPROM data back to the FRM module.

The FRM3 module will be successfully repaired and ready to reinstall in the vehicle.
