2004 Oldsmobile Bravada RWDSECTION Test Description
WARNING: This page is about a different car, the 2003 Pontiac Sunfire, 2003 Pontiac Grand Am, 2003 Oldsmobile Alero, and 2003 Chevrolet Cavalier. However, it is still accessible from the selected car via links, so may be relevant.

The numbers below refer to the step numbers on the diagnostic procedure.

  1. 1  - 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  - 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. Refer to DIAGNOSTIC AIDS .
  4. 4  - This step identifies any unique or unusual criteria required to run the diagnostic test in the event the universal set procedure does not. This information is located in the service information under Conditions for Running the DTC Test.
  5. 5  - The I/M System Status only verifies whether 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.
