OBD2 ECU Car Memory Backup Tool Emergency Battery Replacement

Features: Many on-board computers control cars equipped with modern electronic control systems. In the event of a power outage or a change in battery level, some information stored in the on-board computer is lost. To prevent this, a backup memory is used to preserve on-board computer data, such as information displayed on the instrument panel, digital clock, radio, electric mirrors, etc. Thus, even in the event of a battery replacement, this data is not lost, saving time and increasing efficiency. The device has power indicator, undervoltage indicator, and overload protection functions. The diagnostic device connects directly to the on-board computer and displays power and undervoltage indicators. Powering the device with a 12V battery ensures that the on-board computer settings are retained when the battery is replaced and avoids the power supply issues associated with using a 9V battery. The product is equipped with fuses to protect the on-board computer from accidental damage. Check the connection with the vehicle: a green indicator light indicates normal communication. Also, test the backup battery indicator. If the backup battery voltage is insufficient, a red indicator light will illuminate to warn you. If communication with the vehicle is normal and the battery is sufficiently charged, two green indicator lights will illuminate. You can then safely replace the vehicle's battery.
