compliance criteria for ignition systems and an examination of the On—Board
Diagnostic II (OBD II) system. Based on the results of the OBD 11 system test

affect the operation of the vehicles‘ OBD I! system. In addition, it is concluded

assure that the exempted add—on or modified part continues to meet the
