Inspection/Maintenance System Check: Procedure

    NOTE: Many DTC related repairs will instruct the technician to clear the DTC information. This procedure will reset ALL of the I/M System Status indicators to NO, and require performing the I/M Complete System Set Procedure.
  1. Did you perform the Diagnostic System Check-Engine Controls? If yes, go to next step. If no, see DIAGNOSTIC SYSTEM CHECK - ENGINE CONTROLS  under SELF-DIAGNOSTIC SYSTEM. Repair any DTCs or driveability concerns that would prevent the I/M System Status tests from completing. Did you find and repair a DTC or driveability concern? If yes, go to step  3. If no, go to next step.
  2. Review any service bulletins for software updates that may prevent I/M readiness. Perform any reprogramming or repairs indicated by the service bulletins. Was a reprogramming or repair service required? If yes, see INSPECTION/MAINTENANCE COMPLETE SYSTEM SET PROCEDURE . If no, go to next step.
  3. With a scan tool, observe the I/M System Status display. Is more than one test indicating a NO status? If yes, see INSPECTION/MAINTENANCE COMPLETE SYSTEM SET PROCEDURE . If no, go to the I/M System Set Procedure for the indicated system.
