This maintains a continuous low-level power supply to the car's ECU and onboard computer while the main battery is disconnected, preventing any stored settings or calibration data from being lost.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What car settings does this memory saver protect?\u003c\/h4\u003e\n\u003cp\u003eA: It protects a wide range of stored settings including your digital clock, dashboard information, radio presets, memory seat positions, ABS calibration, anti-skid system data, electric mirror settings, and other ECU-stored parameters that would otherwise reset when the battery is disconnected.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is the AER BT-30 compatible with all vehicles?\u003c\/h4\u003e\n\u003cp\u003eA: This tool is compatible with most OBD2-equipped vehicles, which includes virtually all cars and light trucks manufactured for sale in the United States after 1996. Simply plug it into the standard 16-pin OBD2 port (usually located under the dashboard near the steering column) before disconnecting your battery.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What external power source do I need to use this cable?\u003c\/h4\u003e\n\u003cp\u003eA: You need a stable 12V DC power source — a portable car jump starter, a second 12V battery, or a DC power supply will all work. Connect the battery clips (red to positive, black to negative) to your external power source, then plug the OBD2 connector into the port before disconnecting the car's main battery.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"How does the AER BT-30 OBD2 ECU memory saver cable work?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"The AER BT-30 plugs into your vehicle's OBD2 diagnostic port and connects via battery clips to an external 12V power source (such as a portable jump starter or secondary battery).
