Monitor Preliminary Checks:

Plug a scan tool into the vehicle's Data Link Connector (DLC).
Turn the ignition, KEY ON - ENGINE OFF. Watch for the MIL lamp to illuminate during the bulb check. The MIL lamp must have illuminate. If not, repair the MIL lamp.
Using a scan tool check for Powertrain related DTCs.

Verify that no emissions-related DTCs are present. If an emissions-related DTC is present, the OBD II monitors may not run and the CARB Readiness will not update.
The emissions-related DTC needs to be repaired and then cleared. By clearing DTCs, the OBD monitors must be run and completed to set the CARB Readiness Status.

Using a scan tool check the CARB Readiness Status.

Do all of the CARB Readiness Status Locations read YES?

YES - all monitors have been completed and this vehicle is ready to be I/M or emission tested.
NO - then the following procedure needs to be followed to run/complete all available monitors.

NOTE:

Only complete the monitors, which are not YES in the CARB Readiness Status. Specific criteria need to be met for each monitor. The most efficient order to run the monitors has been outlined below, including suggestions to aid the process.
