V3 Read a Controller

Authors list

Follow these steps to read the selected controller.

NOTE: Not all Supported controllers can be read.  Some vehicle manufacturers have disabled the ability to read the contents of a controller from the factory.  In these cases, EFILive customers will need to obtain base files from an alternative source. Some EFILive Custom Operating Systems are written to non-readable memory.  These files cannot be read from controller.  Refer to the Problems Reading a Controller article for further information.

Standard Menu

  1. Configure FlashScan/AutoCal V3 for BBX features if not already setup.
  2. Connect your FlashScan/AutoCal V3 device to your vehicle.
  3. Turn the vehicle ignition to the On or Accessory position (vehicle must not be cranked/running when reading).
  4. Navigate to the Tune Tool -> F1 Tuning -> F1 Read Tune menu option.
  5. Select correct controller type from BBX configured controllers.
  6. Click the ✔ button to initiate the read operation.

  7. While the ECM is reading a Progress bar will display for the user to visually track the read.
  8. When the read process is complete the saved file will display. Select X to close this message.

    1. Turn the vehicle ignition Off.
    2. Click on the Start button to begin the countdown timer.
