Diagnostics in this information assume a certain skill level and knowledge of Ford-specific diagnostic practices. REFER to Diagnostic Methods in Service Information for more information.

NOTE: The BCM utilizes 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. CMDTCs have an additional 2-character DTC status code suffix to assist in determining DTC history.
