  1. Start the engine and warm it up completely.
  2. Clear the DTC from the PCM memory using the WDS or equivalent.
  3. Verify the following conditions and correct if necessary:
    • All accessory loads (A/C, headlights, blower fan, rear window defroster) are off.
  4. Verify that all of the following PIDs are within the following specifications. All PIDs must be within specifications from Step 5 to Step 6.
    • BARO:above 72.2 kPa {542 mmHg, 21.3 inHg} 
    • IAT:5-35°C {41-95°F} 
    • FTL:15-85% 
    • VPWR:above 10.9 V 
  5. With the vehicle stopped, race the engine at the engine speed indicated, and then drive the vehicle as shown inFig 1. The driving conditions before driving at constant speed are not specified. If possible, monitor RPM PID for engine speed during this procedure.
