The purpose of the I/M Complete System Set Procedure is to satisfy the enable criteria necessary to execute all of the I/M readiness diagnostic tests, and complete the trips for those particular diagnostic tests. When all diagnostic tests are completed, the I/M System Status indicators are set to YES. Perform this test when more than one or all of the I/M System Status indicators are set to NO.
• | The engine coolant temperature (ECT) is less than 56°C (133°F). |
• | The intake air temperature (IAT) is more than 7°C (20°F). |
• | The transmission fluid temperature is between 20-130°C (68-266°F). |
If a step is interrupted before completion, perform the remaining portion of the set procedure. Any portion of the set procedure that requires the engine at operating temperature may be repeated. This will allow most of the diagnostic tests to run and the remaining tests can be performed using the individual system set procedures.
The numbers below refer to the step numbers on the diagnostic table.
Ensure that you perform the I/M System Check before performing this test. Failure to do so may result in difficulty updating the status to YES.
This step initiates the Component Monitoring Tests.
The cruise portion of the step runs a portion of the Component Monitoring Tests and to prepare for the remaining tests.
The acceleration portion of the step completes the Component Monitoring Tests and the idle portion completes the Misfire Monitoring diagnostic tests.
Perform the individual system test for any of the systems that do not update to YES.
The I/M System Status only reports on whether or not a diagnostic test has run, not the outcome of the test. If any emission related DTC sets after the tests are complete, the DTC will require diagnosis.

Important: Once the engine is started, DO NOT turn the engine OFF for the remaining portion of the set procedure. Important: Do not let the engine idle for more than the specified time. Extended idling may prevent some of the required tests from running. Did you complete the action? | 2 minutes | Go to Step 3 | -- | |||||||
Caution: 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. In order for the next group of tests to run, the vehicle must operate in the following conditions:
