CONDITION SUMMARY:
This bulletin is for information only.
Situation: The Touch Screen (TS), also referred to as the Front Control Display Interface Module (FCDIM) or the
High Line Display Front (HLDF), may be wrongly replaced when troubleshooting if issues are incorrectly
attributed to it.
Cause: The TS may be incorrectly diagnosed as the source of the fault and replaced in error.
The Touch Screen is used only for displaying information to the user which will be generated by other
modules in the vehicle. Although the selection is done THROUGH the Touch Screen, it must wait for a
response from the selected module. Therefore, errors in specific functions should be resolved within
the associated control module and should not result in the changing of the Touch Screen.
DO NOT change the Touch Screen for any of the following issues. Refer to the control module
associated with the fault.
Audio Quality
A 'no or poor quality audio' concern should not result in a replaced Touch Screen. The amplifier, speakers and/or
Integrated Audio Module (IAM) should be checked and thoroughly excluded first.
Bluetooth®
The IAM controls all Bluetooth® connectivity. Check the IAM system for correct functionality.
CD/DVD

the IAM although selection is through the Touch Screen.
