An On-Board Diagnostics/Inspection Maintenance (OBD/IM) Vehicle Analysis System (OVAS) includes the hardware and software necessary to access the onboard computer systems on 1996 and newer vehicles, determine On-Board Diagnostics Generation II (OBDII) readiness, and recover stored fault codes using the Society of Automotive Engineers (SAE) standardized link. The analyzer (10) is designed to guide the inspector through the OBDII inspection sequence for a particular vehicle and record the results. Information regarding OBDII scanning anomalies (such as "not ready" status of 1996 Subarus) is maintained in the OBD Vehicle Lookup Table (VLT). In addition, information regarding the Data Link Collector (DLC) location is maintained for 1996 and newer vehicles in the OBD-VLT. This information is downloaded to the OVAS analyzers (10) upon initialization and when the OBD-VLT is updated, and is automatically displayed when vehicles undergoing testing match the vehicle criteria (such as make, model, and model year). <IMAGE>
