On-Board Diagnostic Hand-Held Scan Tool Technology: Adherence to the Society of Automotive Engineers Requirements for Scan Tools and an Evaluation of Overall Scan Tool Capability

摘要

In order to address concerns about On-Board Diagnostics (OBD) equipment capability and the interaction of service technicians with OBD equipped vehicles, EPA evaluated current OBD hand-held scan tool technology. A variety of OBD hand-held scan tools were acquired from aftermarket scan tool and original equipment manufacturers (OEM), and evaluated against the SAE requirements for OBD hand-held scan tools. Also, in response to the public, EPA collected and is providing additional information on additional features and characteristic information about each OBD hand-held scan tool used in this evaluation. This report summarizes this information and provides a brief overview of OBD hand-held scan tool requirements and features.
