Broad Vehicle Compatibility

The OBDII/EOBD Scanner is engineered to be compatible with all OBD II compliant vehicles, including those utilizing the advanced Control Area Network (CAN) protocol. Since 1996, OBD II compliance has been mandatory for all cars and light trucks sold in the United States, encompassing domestic, Asian, and European vehicles. While some 1994 and 1995 gasoline models are OBD II compliant, verifying the Vehicle Emissions Control Information (VECI) Label under the hood will confirm OBD II certification. All OBD II compliant vehicles are required to have a standardized 16-pin Data Link Connector (DLC) typically located under the dashboard.
