Inspection/Maintenance Complete System Set Procedure
|
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 Status indicators are set to YES. Perform the Inspection/Maintenance (I/M) Complete System Set Procedure if any I/M System Status indicators are set to NO.

Conditions for Meeting a Cold Start
|
|
•
|
The ignition voltage between 10 and 15 V.
|
|
•
|
The barometric pressure (BARO) is more than 75 kPa (10.9 psi).
|
|
•
|
The engine coolant temperature (ECT) at start-up is less than 42°C (108°F).
|
|
•
|
The intake air temperature (IAT) is between 2-32°C (36-90°F).
|
|
•
|
The engine is OFF for greater than 6 hours or the following conditions must be met:
|
|
|
-
|
The start-up IAT minus start-up ECT are within 12°C (22°F).
|
|
|
-
|
The start-up ECT minus start-up IAT are within 50°C (90°F).
|
|
•
|
Fuel level is between 25 and 75 %.
|
|
Circuit/System Verification
|
Review the Inspection/Maintenance (I/M) System Status indicators. All I/M System Status indicators should report YES, and no I/M Test DTCs should be present.
|
Inspection/Maintenance (I/M) System Set Procedure
|
|
1.
|
Ensure that the vehicle meets the conditions for a cold start listed above.
|
|
2.
|
If the EVAP I/M System Status indicator displays NO, perform the EVAP Service bay test if applicable.
|
|
3.
|
Turn OFF all accessories; HVAC system, other electrical loads, including aftermarket/add-on equipment, etc., and open the hood.
|
|
4.
|
Set the vehicle parking brake and ensure the vehicle is in park for automatic transmission or neutral for manual transmission.
|
|
5.
|
Start and idle the engine for 2 min.
|
|
6.
|
Refer to
Road Test Warning
.
Close the hood, release the parking brake and accelerate at part throttle to 72-80 km/h (45-50 mph). Keep this speed until the engine reaches operating temperature, 8-10 min .
|
|
7.
|
Continue operation under these conditions for an additional 6 min.
|
|
8.
|
Accelerate at part throttle to 90 km/h (55 mph) with this speed maintained for 2 min.
|
|
9.
|
Release the accelerator pedal for at least 10 s. This will allow the vehicle to enter decel fuel cut-off.
|
|
10.
|
|
Note
|
|
Do NOT touch the accelerator pedal until told to do so. A change in TP Sensor angle or an increase in engine speed may invalidate this portion of the test.
|
Safely stop the vehicle, with the engine in drive for automatic or neutral with the clutch pedal depressed and parking brake applied for manual. Allow the vehicle to idle for 2 min.
|
|
11.
|
Shift the vehicle to park for automatic and neutral for manual. Turn OFF the ignition and exit the vehicle. Do NOT disturb the vehicle for 45 min.
|
|
12.
|
Observe the Inspection/Maintenance (I/M) System Status with a scan tool. All of the I/M System Status indicators should display YES.
|
|
13.
|
If the I/M-system's status indicators for EVAP shows NO, turn off the ignition and make sure that the car meets the conditions for cold start. Repeat steps 6-11 three more times, or until the I/M-system's status indicators for EVAP show YES. If the indicator still shows NO, see
Inspection/maintenance (I/M) test DTC table
to identify which DTC was not run.
|
|
14.
|
If any of the I/M System Status indicators display NO, refer to the
Inspection/Maintenance (I/M) Test DTC Table
for the indicator which did not display YES. The I/M System DTC Table identifies the DTCs associated with each I/M System Status Indicator.
|
|
15.
|
|
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 ignition OFF.
|
Observe the I/M Test DTC information with a scan tool. Verify there are no I/M Test DTCs present.
|
|
17.
|
Observe the Engine DTC information with a scan tool. Verify no DTCs are present.
