Diagnostic Aids

If status does not update, the test outlined in this procedure can be repeated until I/M System Status updates to YES.

The I/M System Status does not indicate whether test has passed or failed, only that a decision was made. When all of the diagnostics for a specific system have run and passed, I/M System Status will update to YES. If a test for a specific system has failed, I/M System Status will update to YES, indicating a determination was made, even if all of the required tests have not run. When a failure occurs, the emission related DTC portion of the I/M System Status display will indicate that MIL is requested. The I/M System Status also registers the DTCs.
