LAUNCH-X431 IMMO Elite Adds BMW CAS3 Key via EEPROM

 This is a guide on how to use LAUNCH X431 IMMO ELITE to add a BMW CAS3 key via EEPROM. Before that, you'll need to upgrade software version to V10.18 or above. You can also use the X431 IMMO PLUS to do same key programming steps.

IMMO >> BMW >> OK >> Anti-Theft Key Matching >> CAS3/CAS3+ IMMO

Warning: connect stabilizer to ensure the voltage is above 13V. If you don't use stabilizer, it will cause CAS module stop working.

MCU Operation >> 0M23S >> Display Connection Diagram

The CAS3 on the car needs to be removed.

Take a look at the CPU model and then select the corresponding model.

Follow the wiring diagram to connect CAS3 module, X-PROG 3.

Step1. Backup Data File

Read Chip ID, it's C412.

Backup Eeprom Data >> Save Data File

Backup FLASH Data >> Save Data File

Anti-theft data back succeeded!

Step2. Generate Dealer Key

Key Operation >> Key Learning >> File generate key >> 0M23S >> Selected the eeprom data >> Selected a blank key position: Key4 >> Generate dealer key

This version needs working key or engine ISN code to generate retailer key. Click "Yes" to continue.

If there is working key, click "Yes".

If there is engine ISN code, click "No".

Put the working key into X431XPROG3 programmer.

Put the new key to be learned into the X431XPROG3 programmer.

Is the current key a smart one? No

Dealer key is generated successfully.

Please save new EEPROM file.

Please write new EEPROM file to CAS, and start the vehicle with new key.

If CAS is ISTAP version, there is no need to write the data.

Step.3 Write Key

Go back to

MCU Operation >> 0M23S >> Restore Eeprom Data >> Select the generated data file to write back

Restore EEPROM data successfully!

Done.

Yanhua Mini ACDP 2 Fixed BMW FEM/BDC Version & Coding Lost

 This is guide to fix the issue(exception repair) of version and coding lost when Yanhua Mini ACDP+ Module 2 are pre-processing BMW FEM/BDC. Please follow this article if you got the same prompt as below:

"Preprocessing the FEM/BDC. The whole preprocess takes 5–20 minutes. Please wait…

If the APP prompts the device to be abnormal or loses connection, please do not do anything, and wait patiently for 20 minutes, the device will automatically completed the remaining operation to ensure the module is normal."

"Please check whether the hotspot is turned on normally, and put the device and mobile phone close to the hotspot named.

If you want to switch to the USB connection, please connect your phone and device with the USB cable, and click Wait then OK in the next dialog box to allow the USB to access the device."

Solution

Reconnect Mini ACDP 2 to Check

BMW >> FEM/BDC >> IMMO/ Mileage >> FEM/BDC(F Chassis) >> OBD detect FEM/BDC

Please use the ACDP standard power adapter(voltage+ 12V, current >= 2.5A).

Please connect the Mini ACDP 2 and FEM/BDC.

Compare the original FEM info to check whether the version and coding are lost.

If they are lost, we can reverse-write the data to repair it.

Click "OK" continuously to exit.

Recover EEPROM Data

Here we're using the add key as an example.

Add key >> FEM/BDC initial programming process >> Manual single step operation >> Recover EEPROM data >> OK

We have prepared ICP memory adapter interface methods for reading and writing 95128/95256

ICP: Memory and MCU in circuit programming.

Please select the connection mode for reading and writing 95128/95256.

Selected "Memory adapter read/write interface: ICP", OK.

Please select the type of memory.

SPI EEPROM: M95128(FEM) or M95256(BDC)

Click "Recover".

Ready to recover 95128/95256 data, click OK to select original data file and recover it to EEPROM.

Select the original data starting with "M".

Recover EEPROM data succeeded.

Recover Coding Data

Recover coding data >> OK

Ready to recover coding data. Click OK to select the backed up coding file.

Selected the original coding data based on date and time.

Recover coding data succeeded!

Return back to OBD detect FEM/BDC again.

Check whether the version info and coding are correct.

If correct, the repair is successful.

Whether the FEM/BDC support preprocess: YES

Have the EFM/BDC been preprocessed: No

Click "OK".

Re-preprocess FEM/BDC as needed.

Done.
