October 30: LEMON manuals on a temporary server, it is slow and having issues, download the manuals you need! Later in November we will switch back to the fast server.
Driving Pattern
- Start the engine. Hold the engine speed at 3,000 rpm without load (in P or N) until the radiator fan comes on.
- Drive at a steady speed between 15 - 75 mph (24 - 120 km/h) for at least 15 minutes, and watch the long term fuel trim. If the long term fuel trim stays at about 1.0, the vehicle is OK or it is a very minor problem. If a significant fault is still present, the long term fuel trim will move up or down while driving.
- When freeze data is stored, drive the vehicle under those conditions instead of Driving Pattern step 2.
- After clearing the DTC by disconnecting the battery or using the scan tool, extend Driving Pattern step 2 to 40 minutes or longer to allow time for long term fuel trim to recover.
- Drive the vehicle in this manner only if the traffic regulations and ambient conditions allow.
