USB ELM327 V1.4 Plastic OBDII EOBD CANBUS ELM 327 Scanner
ELM327 V1.4 is used as an interface to connect virtually all OBD-II
compliant vehicles to a PC for on-board diagnostics (OBD). Such
vehicles are VW, Audi, Seat, Skoda, Opel, Vauxhall, Alfa, Mercedes,
Smart, Renault, BMW, Peugeot, Citroen, Lotus, Ford, Rover, Aston
Martin, Ferrari, etc.
Supports 9 protocols in all - SAE J1850 PWM, SAE J1850 VPW, ISO
9141-2 and ISO 14230-4 as well as CAN Bus ISO 15765-4.
Precision-moulded diagnostic connector made to fit all VW/Audi
vehicles, even those with "tight" trim around diagnostic socket.
USB port design.
Internal EEPROM can remember the last protocol.
Voltage input monitors your vehicle's battery.
