The scan tool System Info menu includes the System Status selection.

Several states require that the vehicle pass on-board (OBD ll system) tests for the major diagnostics prior to having a vehicle I/M emission inspection. Some areas may require that the vehicle pass the OBD II system tests and the I/M emission inspection in order to renew license plates.

Using a scan tool, the technician can observe the System Status (Complete or Not Complete) in order to verify that the vehicle meets the criteria which complies with the local area requirements. Using the System Status display, monitor any of the following systems or a combination of the systems (depending on vehicle make and model) for I/M Readiness:

Important: The System Status display indicates only if the PCM has completed the required tests (DTCs). The System Status display does not necessarily mean that the test has passed. If a failure indication is present for a DTC associated with one of the above systems, that test has failed. Diagnosis and repair are necessary in order to meet the I/M requirement. Verify that the vehicle passes all of the diagnostic tests associated with the displayed System Status prior to returning the vehicle to the customer.

Following a DTC Info Clear, battery disconnect, or a control module replacement, all of the System Status information will be set to Not Complete.

Refer to the diagnostic support information associated with each DTC in order to obtain the Conditions for Running the DTC. The vehicle operating conditions that the system must meet in order for a DTC to run are the Conditions for Running the DTC.

The System Status table shows the DTCs that must run in order for the System Status to indicate a system test has been Completed.
