Inspection/Maintenance Status Reset
System Status For Satisfying the Federal Inspection/Maintenance (I/M) Regulations
The scan tool System Info menu includes the System Status selection.
Several states require that the vehicle pass on-board (OBD II 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:
^ Catalyst
^ Heated Oxygen Sensor (HO2S)
^ Heated Oxygen Sensor (HO2S) Heater
^ Exhaust Gas Recirculation (EGR)
^ Evaporative Emission ([1][2]EVAP)
^ Secondary Air Injection System (AIR)
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.
Scan Tool Tests
The scan tool for some systems depending upon the vehicle make and model include the Service Bay Tests. Use the Service Bay Tests in order to test certain systems and reset the System Status to Complete. The [1][2]EVAP Service Bay Test is included for this vehicle. Refer to the Service Bay Tests for important preliminary instructions.
Service Bay Test
Service Bay Tests are included on the scan tool for some systems depending upon vehicle make and model. They may be used to test certain systems and reset the System Status to Complete. The [1][2]EVAP Service Bay Test is included for this vehicle.
IMPORTANT: Ensure the vehicle meets the following requirements before performing the [1][2]EVAP Service Bay Test. Failure to meet the necessary requirements may cause inaccurate test results. This could lead to mis-diagnosis and unnecessary parts replacement.
The [1][2]EVAP Service Bay Test can be performed when the vehicle meets the following conditions:
^ The Powertrain OBD System Check has been performed ensuring no DTC's are set
^ Battery voltage is between 10.5 and 17.5 volts
^ Fuel level is between 7 Liters (1.85 gals.) and 63 Liters (16.6 gals.) or approximately 1/4 to 3/4 full
^ The key ON engine temperature is between 3.5°C (38.3°F) and 35°C (95°F)
Follow the instructions on the scan tool after ensuring the above conditions have been met. If any of the above conditions are not met the scan tool will display PRESS EXIT upon activating the Service Bay Test.
