Test Description

The numbers below refer to the step numbers in procedure.

  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. This information is located in Conditions for Running DTC.
  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.
