8.
Run five or six medium throttle (50%) accelerations to about 4000 RPM and back to idle (0% throttle) in gear.
9.
Run two or three hard throttle (WOT 100%) accelerations to about 4000 RPM and back to idle (0% throttle) in gear.
10.
Change the oil and filter. Replace the oil per the specification in step 1 and replace the filter with a new PF64 AC Delco oil filter. Inspect the oil and the oil
filter for any foreign particles to ensure that the engine is functioning properly.
11.
Drive the next 500 miles (12 to 15 engine hours) under normal conditions. Do not run the engine at its maximum rated engine speed. Also, do not
expose the engine to extended periods of high load.
12.
Change the oil and filter. Again, inspect the oil and oil filter for any foreign particles to ensure that the engine is functioning
properly.
Emission Test Stations
1.
Your vehicle must have Crankshaft Position System Variation Learn procedure (sometimes called CASE Learn) done on it at a dealership before your
Prep Drive Procedure (#2 below) can be completed. Connected to these instructions is a coupon for a free Crankshaft Position System Variation Learn.
Take it to any GM Dealer to have the procedure done.
2.
Prep Drive Procedure: This procedure is intended to help set the I/M (Inspection and Maintenance) flags used by the emission test stations to determine
emissions compliance. These I/M flags are internal diagnostics checks the ECM (Engine Control Module) must successfully pass prior to CASE Learn (see
above) algorithm being installed. NOTE: It is suggested that you take these instructions with you to the inspection station. Caution: Be aware of road
conditions and traffic at all times. This driven portion of this test is best done on expressway type roads where legal speeds are higher and during times
where light traffic is present. It is recommended to have a passenger call out the instructions to allow the driver to remain focused on the road
conditions and traffic. If the road conditions or traffic force you to abort the driving conditions laid out at any time, simply resume those conditions
when the conditions allow. NOTE: This must be done at an altitude below 6000 ft. Make sure that the MIL (Service engine soon light is out) – NO codes
set. DISCONNECTING THE BATTERY OR CLEARING CODES AFTER PERFORMING THE DRIVE PROCEDURE WILL REQUIRE THIS PROCEDURE TO BE REPEATED.
Part 1 - Soak and Idle
1.
Park the vehicle for 8 hours with battery connected. The vehicle should NOT be parked in the direct sun light. Direct sun light may cause the ECM
to fail a diagnostic test and set a fault code. The coolant/engine temperature must be below 113°F (45° C). NOTE: Turning the ignition on for any
length of time to check the temperature may cause you to have to soak an additional 8 hours.
2.
Start the engine and idle for at least 3 minutes.
Part 2 – On-The-Road Driving
1.
Drive the vehicle with the accelerator between ¼ and ½ throttle for 5 minutes.
2.
Drive at a steady speed with the engine speed between 1200 and 3000 RPM for 10 minutes.
3.
Accelerate to 55 mph.
4.
Shift to a lower gear. Second is preferred but choose a gear that will give you an engine RPM between 2500 and 4000 and not over speed the engine.
5.
De-accelerate in that lower gear without using the brakes to 45 mph. Repeat steps 3 - 5 a minimum of four times. This is to
activate "Decel Fuel Cut-Off".
6.
Put vehicle in drive and continue to drive normally for at least 5 more minutes.
7.
Accelerate vehicle to 55 mph in a gear that will give you an engine speed of approximately 2500-3000 RPM.
8.
De-accelerate in that gear without using the brakes to approximately 40 mph. Repeat steps 7 and 8 a minimum of 4 times.
9.
Come to a stop and idle for 30 seconds (in gear for automatic transmission).
10.
Turn off engine and allow to sit for at least 30 seconds.
11.
Restart engine and repeat steps 1 through 9.
12.
That completes the Emission Test Station - Prep Drive Procedure.
Coupon for Crankshaft Position System Variation Learn Procedure

coupon, located on the last page and take the coupon and vehicle to your GM Dealer to have CASE learn performed.
Install the Emission Label
Install the Emission Certification Label in a visible location on the hood or on the dash.
