Inspection/Maintenance System Check: Procedure

  1. Perform POWERTRAIN DIAGNOSTIC SYSTEM CHECK  under SELF-DIAGNOSTIC SYSTEM. If DTC or driveability problems were repaired using powertrain diagnostic system check, go to step  3. If no DTC or driveability problems were repaired using powertrain diagnostic system check, go to next step.
  2. 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, see INSPECTION/MAINTENANCE COMPLETE SYSTEM SET PROCEDURE . If reprogramming or repair service is not required, go to next step.
  3. Using scan tool, observe I/M SYSTEM STATUS display. If more than one test indicates a NO status, see INSPECTION/MAINTENANCE COMPLETE SYSTEM SET PROCEDURE . If only one test indicates a NO status, go to appropriate I/M system set procedure for indicated system.
