Some 2008-2009 F-Super Duty, Expedition, Explorer, Explorer Sport Trac, Mountaineer, Fusion, Milan, Mustang,, Edge and 2008 F-150 vehicles equipped with Single CD and CDX6 Audio Control Modules (ACM), may exhibit either a speaker pop noise and/or a condition where the ACM is completely inoperative or will not power on.
Follow the Service Procedure steps to correct the condition.
The speaker pop typically happens after an extended drive period when vehicle is warm and opening/closing a door; however, it may happen anytime the (ACM) is turned off. Using the vehicle heater through the instrument panel (IP) panel vents (on high setting) may also cause the condition to repeat more often. The ACM may be completely inoperative, blank. or locked up. It may be caused by a software lockup event within the ACM.
Reprogram the ACM to the latest calibration using IDS 63.02 and higher. This new calibration is not included in the VCM 2009.9 DVD Calibration files may also be obtained at www.motorcraft.com.
An ACM replacement will be necessary for 2008 F-150 for the above symptoms, it can not be reprogrammed with IDS. Reference Workshop Manual, Section 415-00 for removal and installation instructions. Please specify speaker pop noise/lock up on the 1878 form when ordering a replacement ACM for F-150.
