The Snap-on Soft-Sided Memory Saver, No. EESM500, is designed to preserve the vehicle’s on-board computer settings while service is being performed. This memory saver provides 12V power to the vehicle’s computer system, saving settings such as radio, seat position, DTC’s, keyless entry and more. Users can connect the device two ways: With the built-in 42" OBDII cable or 12V accessory plug. The soft-side case is designed to prevent scratching or denting vehicle’s interior and console, and a non-skid bottom will not slip and helps protect vehicle surfaces.
