Safety Instructions
- A sudden interruption of power supply or switching off the ignition during the flashing process may result in an incomplete write operation. This can cause severe damage to the engine control unit (ECU) or transmission control unit (TCU).
- Before flashing, ensure that the vehicle’s battery is sufficiently charged. Ideally, use a battery charger. Switch off unnecessary electrical consumers such as ventilation, lights, and multimedia systems to preserve battery power.
- Never interrupt the flashing process. Follow the instructions in the Windows application carefully.
- Only perform the flashing process in a safe and secure environment, where no danger arises to yourself or others in case the vehicle becomes inoperable.
- In vehicles with a constant power supply to the OBD2 port, leaving the eFlash device connected may lead to battery drain. Remove the eFlash from the OBD2 port when not in use.
