Several states require that a vehicle pass On-Board Diagnostic (OBD) system tests and the Inspection/Maintenance (I/M) emission inspection in order to renew license plates. This is accomplished by viewing the I/M system status display on a scan tool. Using a scan tool, the I/M system status can observed in order to verify that the vehicle meets the criteria that complies with local area requirements.
