Abstract
This final rulemaking revises requirements associated with on- board diagnostic (OBD) systems. The federal OBD rulemaking, published February 19, 1993, allowed for compliance with California OBD II requirements to satisfy federal OBD requirements through the 1998 model year. The California Air Resources Board has recently revised their OBD II requirements. This rulemaking promulgates appropriate revisions to federal OBD regulations such that compliance with the recently revised OBD II requirements will satisfy federal OBD. This rulemaking does not require that manufacturers comply with OBD II anti-tampering provisions. OBD systems in general provide substantial ozone benefits.
