No.... Important: Do NOT perform this procedure if DTCs are set. Without Scan Tool - Learn Procedure 1. Start and idle the engine in PARK for 3 minutes. 2. With a scan tool, monitor desired and actual RPM. 3. The ECM will start to learn the new idle cells and Desired RPM should start to decrease. 4. Ignition OFF for 60 seconds. 5. Start and idle the engine in PARK for 3 minutes. 6. After the 3 minute run time the engine should be idling normal. Important: During the drive cycle the check engine light may come on with idle speed DTCs. If idle speed codes are set, clear codes so the ECM can continue to learn. ^ If the engine idle speed has not been learned the vehicle will need to be driven at speeds above 70 km/h (44 mph) with several decelerations and extended idles. 7. After the drive cycle, the engine should be idling normally. ^ If the engine idle speed has not been learned, turn OFF the ignition for 60 seconds and repeat step 6. 8. Once the engine speed has returned to normal, clear DTCs and return to the diagnostic that referred you here.
