DESCRIPTION

U.S. On-Board Diagnostics (OBD) II Retrofit Program

This service information bulletin can be used to address customer concerns regarding state OBD II emission inspection and maintenance testing. 1996 and 1997 GM vehicles that were originally designed and built for sale in Canada, and now reside in the U.S., may require U.S. Federal calibrations and/or components to meet U.S. Federal OBD II requirements. Customers may be referred to GM dealers with concerns about passing their state OBD II emission inspection and maintenance test for this reason. This bulletin addresses the procedures necessary to retrofit a Canadian designed vehicle to meet U.S. Federal OBD II requirements.
