Some info to help (and this will only work IF the file in your car is suited properly):

1. Engine cold start, idling, approximately 3 minutes. Evaluated:
• Secondary Air System
• Evaporative Leak Detection

2. Constant driving at 20 to 30 MPH, approximately 4 minutes. Evaluated:
• Oxygen Sensors - Achieved “Closed Loop” Operation
• Oxygen Sensors - Response Time and Switching Time (Control Frequency)

3. Constant driving at 40 to 60 MPH, approximately 15 minutes (sufficient vehicle coasting phases included). Evaluated:
• Catalytic Converter Efficiency
• Oxygen Sensors - Response Time and Switching Time (Control Frequency)

4. Engine idling, approximately 5 minutes. Evaluated:
• Tank-Leak Diagnosis (DMTL Equipped Vehicles after KL 15 - ignition - is switched OFF)

NOTE: The diagnostic sequence illustrated above will be interrupted if:
• The engine speed exceeds 3000 RPM.
• Large fluctuations in the accelerator pedal position.
• The driving speed exceeds 60 MPH.

Again - this will work ONLY if the calibration in your car allows it to.
