Inspection/Maintenance System Check: Description
WARNING: This page is about a different car, the 2003 Pontiac Grand Prix, 2003 Chevrolet Malibu, and 2003 Buick Century. However, it is still accessible from the selected car via links, so may be relevant.
Several states require that a vehicle pass On-Board Diagnostic (OBD) system tests and I/M emission inspection in order to renew license plates. This is accomplished by viewing the I/M SYSTEM STATUS display on scan tool. Using a scan tool, the technician can observe the I/M system Status to verify that vehicle meets the criteria that complies with the local area requirements.
