MODULE NAMES MATCH THE DIAGNOSTIC SCAN TOOL

Module names and PID names in this article match the Ford diagnostic scan tool: IDS or FDRS.

The same diagnostic scan tool module name is found in some DTC definitions (for example, U024B Lost Communication with Seat Control Module "G").

MODULE DESCRIPTIVE NAMES

A descriptive name is sometimes added to the diagnostic scan tool name to clarify module function. The descriptive name will be followed by the diagnostic scan tool acronym in brackets.

Example: "Driver Active Motion Seat Module [SCMG]".
Driver Active Motion Seat Module is the descriptive name added to clarify the function of the SCMG.
The SCMG acronym is used by diagnostic scan tool, defined as "Seat Control Module G".
