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