Road Test - Adaptive Drive Cycle

NOTE: Always drive the vehicle in a safe manner according to driving conditions and obey all traffic laws.

1. Connect the scan tool to the Data Link Connector (DLC).

2. NOTE: Do not clear the PCM Keep Alive Memory (KAM).
Using the scan tool, clear the adaptive table before conducting an adaptive drive cycle test.


3. Verify the transmission fluid is at normal operating temperature, between 80°-82°C (176°-180°F). If the transmission fluid is not at operating temperature, drive the vehicle until the operating temperature is reached.

4. NOTE: Make sure the transmission fluid is at normal operating temperature before continuing with this step.
Drive the vehicle on a level road surface performing the adaptive drive cycle procedure.

1. Accelerate from a stop with light throttle to 24 km/h (15 mph) then release the accelerator pedal.

2. Gently brake bringing the vehicle to a stop and hold the brake for 6 seconds.

3. Repeat Substeps 1 and 2 an additional 5 times.

4. Accelerate from a stop with light throttle so the 1-2, 2-3 and 3-4 shifts occur with engine speeds between 1,700-2,000 rpm.

5. Continue accelerating until the vehicle speed reaches 80 km/h (50 mph) or a 5-6 upshift is achieved.

6. Gently brake bringing the vehicle to a stop and hold the brake for 10 seconds.

7. Repeat Substeps 4, 5 and 6 an additional 3 times.
