[QUOTE="dsp, post: 16930812, member: 154070"] I followed this procedure the last time I had a problem with monitors not being ready. For some reason it didn't work with the red key, but all monitors were ready once I ran through this with the regular key. Hope this helps. [B]How To Complete Ford Mustang Drive Cycle The following procedure is directly from Ford and designed to complete the OBDII monitors required to get your Ford Mustang to pass the OBDII Monitors portion of the smog check, also known of the I/M readiness test. You may use a scan tool in order to monitor the status of the emission monitors as your Ford Mustang is being driven. START HERE - Drive Cycle Recommendations: 1.Emission monitors (readiness flags) will complete quicker when using a "steady foot" driving style during cruise or acceleration modes. Operating the gas pedal in a "smooth" manner will minimize the time required for monitor completion. 2. Fuel tank level should be between 1/2 and 3/4 fill during the drive cycle in order to allow the EVAP monitor to run. 3.The Evaporative Monitor can only operate during the first 30 minutes of engine operation. During the EVAP portion of the drive cycle, drive in a smooth fashion to minimize "fuel slosh". Drive Cycle Preparation - 1. If using a scan tool, go ahead and connect it now. Turn key on with the engine off. Cycle key off, then on. Select the appropriate vehicle make and model on your scan tool. Start your Ford Mustang WITHOUT returning to Key Off. Idle the vehicle for 15 seconds, and then drive at 40 MPH until engine coolant temperature is at least 170°F, which is normal engine operating temperature. 10 to 15 minutes of drive will achieve this. HEGO Monitor - 5. Cruise at 40 MPH for up to 4 minutes. EVAP Monitor - 6. Cruise at 45 to 65 MPH for 10 minutes (avoid sharp turns and hills). Catalyst Monitor - 7. Next, drive your Ford Mustang in stop and go traffic conditions. Include five different constant cruise speeds, ranging from 25 to 45 MPH over a 10 minute period. EGR Monitor - 8. From a stop, accelerate to 45 MPH at 1/2 to 3/4 throttle. Repeat this pattern 3 times. SEC AIR/CCM (Engine) - 9. Bring your Ford Mustang to a stop. Idle with transmission in drive (neutral for M/T) for 2 minutes. CCM (Trans) - 10. If your Ford has a manual transmission, go ahead and accelerate from 0 to 50 MPH, continue to step 11. For Automatic Transmissions, start from a stop and in overdrive, then moderately accelerate to 50 MPH and cruise for at least 15 seconds. Stop the vehicle and repeat without overdrive to 40 MPH cruising for at least 30 seconds. While at 40 MPH, activate overdrive and accelerate to 50 MPH and cruise for at least 15 seconds. Stop for at least 20 seconds and repeat step 10 five times. Misfire & Fuel Monitors - 11. From a stop, accelerate to 65 MPH. Decelerate at closed throttle until 40 MPH (no brakes). Repeat this 3 times. Readiness Check - 12. If using a scan tool, go ahead and access the ON-Board System Readiness (OBDII monitor status) function on the scan tool. Determine whether all emission monitors have completed. Evap Monitor "Bypass" - 13. Park vehicle for a minimum of 8 hours. Repeat steps 2 through 12.[/B] [/QUOTE]
