System Status For Inspection/Maintenance (I/M)
The System Information menu on the scan tool contains the I/M System
Status selections. The technician can observe the System Status (COMPLETE
or NOT COMPLETE) to verify whether or not the vehicle complies with the local
area I/M requirements. The System Status display allows the technician to
monitor any of the following systems or a combination of the systems (depending
on vehicle make and model) for I/M Readiness:
• | Exhaust gas recirculation (EGR) |
• | Evaporative emission (EVAP) |
• | Secondary air injection system (AIR) |
Important: The system status display indicates only if the PCM has completed the
required tests (DTCs). The 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 Clear DTC Information, battery disconnect, or a PCM 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.
