Inspection/Maintenance Complete System Set Procedure
Diagnostic Instructions
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). |
• | Inlet 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 in the Preface section.
- 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 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.
- Observe the I/M Test DTC information with a scan tool. Verify there are no I/M Test DTCs present.
- Observe the ECM DTC information with a scan tool. Verify no DTCs are present.
