How to Clone Smart 450 BCM Using Xhorse Multi Prog

 In this article, we will explore the process of cloning a Smart 450 Body Control Module (BCM) using the Xhorse Multi Prog tool. The goal is to read and transfer data from the original BCM to a replacement unit, ensuring seamless functionality.

Step 1: Preparing the BCM

The first step involves connecting the Multi prog tool to the BCM:

Pinout Identification — The BCM uses a 4-wire connection (power, ground, and two data lines).

Smart 450 BCM pinout (for multi prog, vvdi prog and x-prog etc). VVDI Prog can also clone smart 450 bcm.

Tool Connection — The Multiprog is attached to the BCM, ensuring proper contact with the pins.

Step 2: Reading the Original BCM Data

Read the data from the original BCM:

  • Reading EEPROM and Flash — The tool extracts data from both the EEPROM and Flash memory of the BCM.
  • Verification — The Multiprog automatically performs a verification check to ensure the data is read correctly.

Key Observations:

  • The BCM contains a Motorola 912 256 chip, which is unsecured (not encrypted), making the cloning process straightforward.
  • The Chip ID (processor identifier) is visible, confirming compatibility.

Step 3: Writing Data to the New BCM

After successfully reading the original data, the next step is transferring it to the replacement BCM:

  1. Writing EEPROM and Flash — The same data is written to the new BCM.
  2. Automatic Verification — The tool cross-checks the written data to ensure accuracy.

Step 4: Testing and Final Steps

Once the cloning is complete:

  • The replacement BCM should function identically to the original.

This process is efficient, taking only a few minutes, and works well due to the unsecured Motorola chip. For those attempting this, referencing online pinout diagrams is essential for a smooth workflow.

PCMTuner Unlock Audi SIMOS 8.6 in BSL Mode

Image
 SIMOS 8.6 requires unlocking in BSL mode by the appropriate module. BSL is usually boot mode for unlock. Same as PCR2.1 . Example: Audi A7 2012 2.8 fsi simos 8.6 unlock, after read/write simos8.6 with pcmtuner successfully. all resistor 1 kom How to work with blocks that require unlocking (PCR2.1, SIMOS8.6): 1) Check the current lock status in the car, if the check is disabled, you can go to read-write, otherwise follow the instructions 2) Remove the unit from the car, open it, transfer the processor to BSL mode using the connection below (PCR2.1, SIMOS8.6), the work as a whole as in the package 53 (you can use tools like powerbox, and you can do without them) SIMOS8.6 Unlock pcmtuner pinout Red — +12, Black — GND, Yellow — CAN-HIGH, Blue — CAN-LOW 3) Choose "SIMOS8.6 (EEPROM/UNLOCK/BSL) or PCR2.1 (EEPROM/UNLOCK/BSL)" depending of ECU type 4) Click Identification — save ECU data somewhere in a text file. 5) Click Read — save the EEPROM 6) Given that EC...

 Question: Has someone maybe pinout/Wiring diagram for Siemens ECU for Renault 237106288r EMS3155? Renault Megane IV 2016. I tried to read on bench with pcmtuner but no luck. Thank you Solution: Try module module 59: 1.2T EMS3155 UDS (TC1782/2.5MB) or module 22: Nissan: Juke 1.2T EMS3155 (TC1782/2560KB) you can try, UDS requires immobiliser authorization on many ECU so cannot do bench just read it in obd with pcm tuner . not start in bench because immo active and key.

 What's the difference between Foxflash and the new KT200 II 2nd generation ecu/tcu programmer? Foxflash: free online update to get more protocols. KT200 II: it's a separate new hardware with new protocols Foxflash: more stable KT200: less stable, often bricks ECU Foxflash: reading and writing is faster and stable in the long run. Direct update foxflash online to get KT200 II protocols for example: Marelli 8GMC BENCH Delco E38 OBD BENCH E67 BENCH E84 BENCH E92 OBD BENCH SIM2K-305 BOOT Bosch MG1CA007 BENCH Delphi DCM7.24 OBD Phoenix L40 OBD EDC17C11 BENCH BOOT MD1CS069 OBD BENCH New Clone function MEDC17 FCA HYUNDAI JAGUAR LAND ROVER SUZUKI TOYOTA Transmission protocols BOSH 6L45 6L50 6L80 6L90 BENCH see http://www.pcmtuner.org/foxflash-update-dcm7-24-e38-e92-e83-e0-e39a-via-obd/ Users are allowed to update the above protocols to foxflash directly online without purchasing any new hardware or adapters.
