Module replacement - ECUs, UCH, ESLs and more

Using the Abrites diagnostics for Renault/Dacia you can replace many modules - ECUs, UCH, ESLs, etc. Here is what you need to do, using the UCH as an example.

Procedure

1. Read the PIN code

Read the PIN code from the car and copy it, as described in Key Learning.

2. Check whether the module is virgin

Go to "Live values" and confirm whether the module (in this case the UCH) is virgin or not.

• If it is virgin - you can adapt it.
• If it is not virgin - you can renew it.

"Blank body computer" says NO, meaning that the UCH needs to be renewed:

3. Select the UCH type in the Renew menu

4. Renew the unit

5. Adapt it with the PIN and the VIN

Make sure you have the PIN and the VIN.

Once you confirm the needed values, the UCH is adapted. The procedure is the same for ECUs.
