OBD, Bench and Boot Differences
Comparative technical analysis of ECU programming methods.
OBD programming is done via the diagnostic port; it is fast and non-invasive but not possible on all ECU types. In bench mode, the ECU is removed and connected via pinout for broader access. Boot mode is used for locked ECUs or recovery scenarios requiring processor-level access.
The correct method is determined by ECU family, TPROT level and vehicle condition. Wrong method or interruption may require ECU recovery procedures.
