Inspection/Maintenance (I/M) Complete
System Set Procedure
Diagnostic Instructions
• Perform the "Diagnostic System Check - Vehicle
Diagnostic Information: " prior to using this diagnostic
procedure.
• Review "Strategy Based Diagnosis: " for an overview
of the diagnostic approach.
• "Diagnostic Procedure Instructions - Vehicle
Diagnostic Information: " 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 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 volts.
• The barometric pressure (BARO) is more than 75
kPa.
• 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 percent.
Circuit/System Verification
Review the Inspection/Maintenance (I/M) System Status
indicators. All I/M System Status indicators should report
YES.
Inspection/Maintenance (I/M) System Set
Procedure
1. Ensure that the vehicle meets the conditions for a
cold start listed above.
➢ If the EVAP I/M System Status indicator displays
NO, perform the EVAP Service bay test if
applicable.
2. Turn OFF all accessories; HVAC system, other
electrical loads, including aftermarket/add-on
equipment, etc., and open the hood.
3. Set the vehicle parking brake and ensure the vehicle
is in park for automatic transmission or neutral for
manual transmission.
4. Start and idle the engine for 2 minutes.
WARNING
!
Refer to "Road Test Caution: ".
5. Close the hood, release the parking brake and
Accelerate at part throttle to 72-80 km/h (45-50 mph)
with this speed maintained until the engine reaches
operating temperature, 8-10 minutes.
6. Continue operation under these conditions for an
additional 6 minutes.
7. Accelerate at part throttle to 90 km/h (55 mph) with
this speed maintained for 2 minutes.
8. Release the accelerator pedal for at least 10
seconds. This will allow the vehicle to enter the decel
fuel cut off.
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.
9. 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 minutes.
10. 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 minutes.
11. Observe the Inspection/Maintenance (I/M) System
Status with a scan tool. All of the I/M System Status
indicators should display YES.
➢ If the EVAP I/M System Status indicator displays
NO, turn OFF the ignition, ensure that the vehicle
meets the conditions for a cold start, and repeat
steps 6-11 three more times, or until the EVAP I/M
System Status indicator transitions to YES. If the
indicator continues to display NO, refer to the
"Inspection/Maintenance (I/M) System DTC Table"
to identify the DTCs that did not run.
➢ If any of the I/M System Status indicators display
NO, refer to the "Inspection/Maintenance (I/M)
System 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.
