Inspection/Maintenance (I/M) System Set Procedure

    WARNING:

    Refer to Road Test Warning .

    NOTE:

    Since the internal combustion engine must run in order for the I/M monitors to execute, it is suggested that the vehicle state of charge be depleted prior to performing the road test.

  1. Vehicle ON, accelerate to a speed greater than 40 km/h (25 MPH) with engine speed greater than 1800 RPM.
  2. Maintain the vehicle speed and engine speed until the engine reaches normal operating temperatures.
  3. Park vehicle and ensure that the vehicle meets the conditions for a cold start listed above.
  4. Allow vehicle to sit undisturbed for a minimum of 8 hours.
  5. Vehicle in Service Mode, observe the Inspection/Maintenance (I/M) Monitors with a scan tool. All of the I/M System Monitors should display YES.
    • If any of the I/M System Monitors display NO, refer to the Inspection/Maintenance (I/M) System DTC Table  for the monitor which did not display YES. The I/M System DTC Table identifies the DTCs associated with each I/M System Monitor.
  6. NOTE:

    An I/M Test DTC will not be stored or erased from the ECU except at the end of trip processing, which occurs 5 s after Vehicle OFF.

  7. Observe the I/M Test DTC information with a scan tool. Verify there are no I/M Test DTCs present.
  8. Observe the ECM DTC information with a scan tool. Verify no DTCs are present.
