Electromagnetic Compatibility Specification
For Electrical/Electronic
Components and Subsystems
Foreword
This engineering specification addresses Electromagnetic Compatibility (EMC) requirements for
electrical/electronic (E/E) components and subsystems for Ford Motor Company (FMC). This
specification is the direct link from ARL-09-0466. These requirements have been developed to assure
compliance with present and anticipated regulations in addition to customer satisfaction regarding the
EMC of vehicle E/E systems. This specification replaces ES-XW7T-1A278-AC.
EMC-CS-2009 is applicable for all E/E components/subsystems slated for use on 2013 Ford vehicle
programs in addition to E/E component/subsystems whose commercial agreements are signed after
October 1, 2009.
EMC-CS-2009 is available for download from the Ford EKB in addition to www.fordemc.com
Corrections and/or editorial updates to this specification will be made as required and without prior
notification to the user. It is recommended that the user verify they have the latest version of the
specification prior to application to their E/E component/subsystem.
Information regarding differences between these specifications may be found at http://www.fordemc.com
