Inspection/Maintenance Complete System Set Procedure

Diagnostic Instructions

* Perform the Diagnostic System Check - Vehicle Diagnostic System Check - Vehicle prior to using this diagnostic procedure.
* Review Strategy Based Diagnosis Strategy Based Diagnosis for an overview of the diagnostic approach.
* Diagnostic Procedure Instructions Diagnostic Procedure Instructions provides an overview of each diagnostic category.

Description

The purpose of the Inspection/Maintenance (I/M) complete system set procedure is to satisfy the enable criteria necessary to execute all of the I/M readiness diagnostics and complete the trips for those particular diagnostics. When all I/M monitored diagnostic tests are completed, the I/M System Monitor Indicators are set to YES. Perform the Inspection/Maintenance (I/M) Complete System Set Procedure if any I/M System Monitor indicators are set to NO.

Conditions for Meeting a Cold Start

* Ignition voltage between 10-32 V.
* Barometric pressure (BARO) between 10-16 psi.
* Engine coolant temperature (ECT) less than 40°C (104°F).
* Intake air temperature (IAT) between 4-45°C (39-113°F).
* Fuel level between 10 and 90 %.

Circuit/System Verification

Vehicle in Service Mode, observe the scan tool Inspection/Maintenance (I/M) System Monitor and the I/M test DTCs. All I/M System Monitors should display YES, and there should be no I/M Test DTCs.

Inspection/Maintenance (I/M) System Set Procedure

Warning: Refer to Road Test Warning Road Test Warning.

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) Test DTC Table Inspection/Maintenance (I/M) Test 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.

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.

6. 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 Diagnostic Trouble Code (DTC) List - Vehicle Diagnostic Trouble Code (DTC) List - Vehicle and refer to Inspection/Maintenance System Check Inspection/Maintenance System Check.

7. Observe the ECM DTC information with a scan tool. Verify no DTCs are present.

• If a DTC is set, diagnose using the Diagnostic Trouble Code (DTC) List - Vehicle Diagnostic Trouble Code (DTC) List - Vehicle. After repairs, perform the Inspection/Maintenance Complete System Set Procedure to verify no further DTCs are set.
