Test Description

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

  1. 1 -  Make sure that you perform the Inspection/Maintenance System Check before performing this test. Failure to do so may result in difficulty updating the status to YES.
  2. 2 -  The Catalyst Test during the idle period immediately following the cruise period.
  3. 3 -  This step identifies a first failure of a type "B" DTC. A DTC only appears on the I/M System Status display when the DTC becomes a MIL illuminating DTC. This occurs on the second failure of a type "B" DTC. A first failure of a type "B" DTC will not allow the I/M System Status to update to YES. See DIAGNOSTIC AIDS .
  4. 4 -  This step helps identify any unique or unusual criteria required to run the diagnostic test if the universal set procedure does not. See CONDITIONS FOR RUNNING .
  5. 5 -  The I/M System Status only reports on whether or not a diagnostic has run, not the outcome of the test. If any Emission Related DTC sets after the tests are complete, the DTC will require diagnosis.
