It is a Jeep Renegade Body Control module, they call them BCM/in Fiat it is BSI.
We are going to clone this BCM. Fiat, Chrysler and Dodge some of them do have similar BCM.
This is a flooded car so the right is original bad unit. First need to read data from the original ECU.
We are using the xhorse multi prog programer. Tried to do it with AVDI or Autel, they don’t even have an option. I/O Terminal doesn’t even have an option. VVDI prog does these also.
Xhorse vvdi does have the option to clone these.
Go to laptop, follow wiring diagram to connect BCM module with multi-prog via the MCU adapter.
Solder GND, VCC, Brown, then orange, add flux and solder that way, double check your connection and make sure everything is good.
Go to Multi PROG software.
Select Immobilizer->Jeep Renegade BCM_>2017. This is the R7F701034 processor.
Read Dflash.
It does have a password so these are secure.
If you have a programmer that reads it but cannot unlock it you are out of luck.
That’s why we need to use the multi prog. It unlocked it and read the Dflash.
Then read the Cflash data. Always read all the data in case something go wrong.
This one takes longer to read as it’s a bigger one.
It’s pretty quick read for this programmer. If you can see 2 minutes 22 seconds for a flash this big it’s a good read. Fast read it’s a total of 3 minutes.
Then we will write both Dflash and Cflash.
You don’t need to write the C flash on some cars.
You do so in this case.
Upload original BCM Dflash and write.
Write Dflash successfully.
We’re going to write the Cflash. Click C Flash and load the original C flash.
Write CFlash completed.
It’s written. We’re just going to unsolder those pinouts clean it and the BCM clone is done.
