Control of Air Pollution From New Motor Vehicles and New Motor Vehicle Engines: Regulations Requiring On-Board Diagnostic (OBD) SystemsAcceptance of Revised California OBD II Requirements

摘要

This notice of proposed rulemaking proposes to revise requirements associated with on-board diagnostic (OBD) systems, as specified by 40 CFR 86.094-17. The federal OBD rulemaking, published February 19, 1993, allowed for compliance with California OBD II requirements as satisfying federal OBD requirements through the 1998 model year. The California Air Resources Board has recently revised their OBD II requirements. The federal OBD regulations require appropriate revisions such that compliance with the recently revised OBD II requirements will satisfy federal OBD.
