What is the Difference Between Ford IDS and FCOM

This post describes comparison of functions of FCOM with original Ford Motor Diagnostics IDS (Integrated Diagnostic System). Control unit selection

Main difference between concepts of program FCOM and system IDS is in user approach to vehicle and its systems. The IDS uses so called Function system, which first chooses function (e.g. Read trouble codes) and then control unit (e.g. PCM). FCOM chooses control unit first and then function. Advantage of second approach is especially similarity with other diagnostic systems (e.g. VCDS,etc.) and consequently more user friendly for those who have not much experience with IDS. Next advantage is easier identification of concrete type of control unit for programming etc. Fault codes

Reading and Clearing Diagnostic Trouble Codes acted like IDS system, all CMDTC (Continuous Memory Diagnostic Trouble Codes) are read and clear from control unit. Identification

Ford IDS does not provide this function, however is possible to display some identification information in Log Viewer This Post: What is the Difference Between Ford IDS and FCOM From ChinaOBD2 Official Blog
