Test Description

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

1. 1
   
   Make sure 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
   
   The EVAP System test runs immediately following the idle period.
3. 3
   
   This step is to identify 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  .
