Engine Control Unit replacement procedure has the following specific steps

Abrites FBS4 Manager is able to personalize a virgin or new unit in ALL cases.

IMPORTANT ! MRD1/MRG1 ECU have a separate procedure for personalization without previously saved data, available a few pages below.

There are 2 general scenarios

  1. Replace the unit when the original unit is available and you can read the FBS4 personalization data

  2. Replace the ECU when no FBS personalization data is available

Here is the procedure from scenario 1 explained briefly, each step will be expanded with more details later in a dedicated section:

  1. Read the FBS personalization data from the original ECU, using OBDII connection in the vehicle, and save the file for later use!

  2. Install a new or virgin unit in the vehicle.

  3. Donor unit can now be virginized if not in virgin state.

  4. Personalize with the already saved FBS data from the original unit - here you will need direct CAN Connection. (Blue CAN Wires)

  5. The vehicle should start normally, there is no need to “Activate” the unit, as it gets activated automatically after 100 ignition cycles, while it operates normally in the meantime.

N.B. ALL virgin or new modules can be personalized with no restrictions!

Here is the procedure from scenario 2 briefly explained, each step will be expanded with more details later in a dedicated section:

  1. Install a new or virgin unit in the vehicle.

  2. Donor unit can now be virginized if not in virgin state or new.

  3. Personalize the unit by OBDII

Supported units when NO PREVIOUSLY PERSONALIZATION DATA IS AVAILABLE
