Some vehicles require ECU unlocking before the ECU can be read. In this case, after selecting the ECU in the Reading ID menu, the device will display some data. Take a photo of this data or enter it above. You will need to find a matching patch, detailed in the next step, using your Calibration ID. After writing the patch to the ECU, reading and writing will be fully enabled.
