Check for applicable Technical Service Bulletins (TSB) for software updates that may prevent Inspection/Maintenance (I/M) readiness. Perform any reprogramming or repairs indicated by TSBs. If reprogramming or repair service was required, go to INSPECTION/MAINTENANCE COMPLETE SYSTEM SET PROCEDURE . If reprogramming or repair service was not required, go to next step.

Using scan tool, observe I/M system status display. If more than one test indicates a NO status, go to INSPECTION/MAINTENANCE COMPLETE SYSTEM SET PROCEDURE . If only one test indicates a NO status, perform appropriate I/M system set procedure for indicated system. See INSPECTION/MAINTENANCE SYSTEM SET PROCEDURE INDEX table.
