Test Description

The numbers below refer to the step numbers in the diagnostic procedures.

1. 1
   
   Make sure that you perform the I/M System Check before performing this test. Failure to do so may result in difficulty updating the status to YES.
2. 2
   
   This step initiates the Component Monitoring Tests.
3. 3
   
   The cruise portion of the step runs a portion of the Component Monitoring Tests and to prepare for the remaining tests.
4. 4
   
   The acceleration portion of the step completes the Component Monitoring Tests and the idle portion completes the Misfire Monitoring diagnostic tests.
5. 5
   
   Perform the individual system test for any of the systems that do not update to YES.
6. 6
   
   The I/M System Status only reports on whether or not a diagnostic test has run, not the outcome of the test. If any emission related DTC sets after the tests are complete, the DTC will require diagnosis.
