2011 Ford Flex SEFACTORY OEM SERVICE PROCEDURE
Inspection and Verification
WARNING: This page is about a different car, the 2012 Ford Flex. However, it is still accessible from the selected car via links, so may be relevant.
This information provides step-by-step module configuration procedures. Carry out the procedure listed in the below chart for the module setting the DTC. Refer to the Diagnostic Trouble Code (DTC) Chart in MULTIFUNCTION ELECTRONIC MODULES for DTCs not listed below.
NOTE:
Some modules on this vehicle utilize a 5-character DTC followed by a 2-character failure-type code. The failure-type code provides information about specific fault conditions such as opens, or shorts to ground. Continuous memory DTCs have an additional 2-character DTC status code suffix to assist in determining DTC history.
