Ford Enhanced (OBD II) Diagnostics

Erase Codes

Refer to “Erase Codes” on page 4-5 of Global OBDII Diagnostics. Perform this KOEO. After erasing the DTCs, verify new ones have not been set using the Read All DTC function.

IMPORTANT

View Data

Until all monitors have ran the absence of a Diagnostic Trouble Code (DTC) does not mean the fault has been fixed.

The View Data function allows you to view the vehicle’s Parameter Identification (PID) data in real time. As the computer monitors the vehicle, the information is simultaneously transmitted to the scan tool. Apart from Read Codes, View Data is the most useful diagnostic function for isolating the cause of a vehicle driveability problem. View data is also used for observing sensor data and the status of switches, solenoids, and relays.

Select View Data from the Ford Function List and press ENTER.
