Inspection/Maintenance System Set Procedure
WARNING:
Road test a vehicle under safe conditions and while obeying all traffic laws. Do not attempt any maneuvers that could jeopardize vehicle control. Failure to adhere to these precautions could lead to serious personal injury and vehicle damage.
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.
- Vehicle ON, accelerate to a speed greater than 40 km/h (25 MPH) with engine speed greater than 1800 RPM.
- Maintain the vehicle speed and engine speed until the engine reaches normal operating temperatures.
- Park vehicle and ensure that the vehicle meets the conditions for a cold start listed above.
- Allow vehicle to sit undisturbed for a minimum of 8 hours.
- 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 appropriate 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.
- Observe the I/M Test DTC information with a scan tool. Verify there are no I/M Test DTCs present.
- If an I/M Test DTC is set, diagnose the DTC using the appropriate DIAGNOSTIC TROUBLE CODE (DTC) LIST - VEHICLE and refer to INSPECTION/MAINTENANCE SYSTEM CHECK.
- Observe the ECM DTC information with a scan tool. Verify no DTCs are present.
- If a DTC is set, diagnose using the appropriate DIAGNOSTIC TROUBLE CODE (DTC) LIST - VEHICLE. After repairs, perform the INSPECTION/MAINTENANCE COMPLETE SYSTEM SET PROCEDURE to verify no further DTCs are set.
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.
