OBDSTAR G3 Replace Renault Logan 2012- BCM UCH

How to replace Dacia Sandero 2013-2019 Continental UCH with JCI using OBDSTAR X300 Classic G3. It is similar to older Renault/Dacia cars.

 

NOTE: You will need G3. X300 DP Plus does not have ECU advanced function.

This may not work on every Renault/Dacia. Always check G3 coverage and function before operation.
Read original UCH information.

Go to ECU Advanced- Renault/Dacia->BCM/UCH
Drop down list and find Logan-> 2012 onwards-> Continental

Read ECU info.
OBDSTAR will read part number, VIN, keys, etc info.

You can read Dflash and extract a PIN code from the BCM / UCH memory.

If failed to read pin code under ECU Advanced function, try to extract pin code via method 2 here.

Autel tools are used to be able to change UCH VIN for these Renault. But it no longer reads pin code.

 

Once you get the pin code. Replace the Continental UCH with the JCI one.

Drop down list and find Logan-> 2012 onwards-> Johnson
