Electrical problem
1996 Ford Taurus 6 cyl Two Wheel Drive Automatic 60000 miles

Where is the computer located in this model. My mechanic suggested that I unplug it for a bit and then drive it to try to get the monitors to read. I can't pass emissions right now, and the dealership told me that it was probably the relay to the air pump, but when I called my mechanic about it he explained that he was leary of this answer because all of the monitors are saying they are not ready or supported. Please help. Thanks

Do you
have the same problem?

The purpose of the OBD-II drive cycle is to execute the OBD-II monitors and identify any concerns with the OBD-II system. The DTC P1000 code will be erased of all OBD-II monitors have completed during the OBD-II drive cycle.
The scan tool will be used to observe the status of each OBD-II monitor at the completion of the OBD-II drive cycle. The completion status of the Exhaust Gas Recirculation (EGR), Heated Oxygen Sensor (HO2S), Evaporative emission (EVAP), secondary Air Injection (AIR) (if applicable) and catalyst efficiency monitors can be monitored during the OBD-II drive cycle by viewing the On-Board Readiness Menu on the scan tool.
WARNING:Strict observance of posted speed limits and attention to driving conditions are mandatory when proceeding through the following drive cycles.

Vehicle Preparation for OBD-II or Monitor Repair Verification Drive Cycle
NOTE:Vehicles equipped with Power Take Off (PTO) must have this system disengaged before proceeding. Verify by viewing the PTO PID for OFF status.

Attach a scan tool and access the ECT, FLI, IAT PIDs. Verify the IAT PID is between 50-100 F (10-38 C). Verify the FLI PID is between 15% and 85% (only available on EVAP Running Loss systems).
Warm the vehicle until the ECT PID reaches a minimum of 130 F (54 C).
Clear all DTC's with the scan tool by pressing clear with the key on engine off. P1000 will remain. Leave the key in the ON position, and start the vehicle.
Access the On-Board System Readiness Menu on the scan tool to view the status of the OBD-II monitors.
Proceed with the OBD-II Drive Cycle or selected monitor repair verification drive cycle. Once started, the engine must not be turned off.
OBD-II Drive Cycle
NOTE:The IAT PID must be between 50-100 F (10-38 C) during the OBD-II drive cycle to enter into all the OBD-II monitors. The FLI PID must be between 15% and 85% at all times.

Drive in stop-and-go traffic with at least 4 idle periods (30 seconds each) while observing the status of the OBD-II monitor on the scan tool. If the Exhaust Gas Recirculation (EGR), Heated Oxygen Sensor (HO2S), Evaporative (EVAP) emission, secondary Air (AIR) (if applicable) or catalyst efficiency monitor have not completed, drive on the highway at a constant speed over 40 mph not to exceed 65 mph for up to 15 minutes. Heavy accelerations, sudden decelerations and wide open throttles are not recommended. If the scan tool sends out a three pulse beep at any time, the OBD-II drive cycle has completed.

NOTE:Vehicles equipped with the EVAP purge flow system or EVAP vapor management flow system monitor do not require EVAP monitor completion to clear the DTC P1000.

If the EGR, HO2S, EVAP, secondary AIR (if applicable) or catalyst efficiency monitor has not completed, perform the corresponding monitor verification drive cycle.

Bring the vehicle to a stop and retrieve Continuous Memory DTCs to verify the DTC P1000 has been erased.
