Driving Pattern
- Start the engine. Hold the engine at 3,000 rpm with no load (in park or neutral) until the radiator fan comes on.
- Drive the vehicle at a speed between 25 - 55 mph (40 - 88 km/h) for at least 5 minutes.
- To test while driving, drive at a steady speed between 25 - 75 mph (40 - 120 km/h) for at least 5 minutes.
- To test at idle, stop the vehicle after step 2, and let the engine idle for at least 5 minutes.
- When freeze frame data is stored, drive the vehicle under those conditions instead of Driving Patterns 3 or 4.
- If you have difficulty duplicating the DTC, retest after turning off electrical components such as the audio system and A/C, and try a different gear position.
- Drive the vehicle in this manner only if the traffic regulations and ambient conditions allow.
