Symptom Chart: Instrument Panel and Interior Switches Illumination

Diagnostics in this article assume a certain skill level and knowledge of Ford-specific diagnostic practices. REFER to: Diagnostic Methods .

Condition	Possible Sources	Action
All illumination (networked and non-networked components) do not dim	Refer to the Pinpoint Test	GO to Pinpoint Test A
All non-networked illumination components are inoperative (networked illumination functions correctly)	Refer to the Pinpoint Test	GO to Pinpoint Test B
One or more non-networked illumination components is inoperative	Refer to the Pinpoint Test	GO to Pinpoint Test C
All non-networked illumination sources are always on (networked illumination functions correctly)	Refer to the Pinpoint Test	GO to Pinpoint Test D
The driver door lock/unlock memory set switch illumination is inoperative or always on	Refer to the Pinpoint Test	GO to Pinpoint Test E
The passenger window control switch illumination is inoperative or always on	Refer to the Pinpoint Test	GO to Pinpoint Test F
The passenger door lock/unlock switch illumination is inoperative or always on	Refer to the Pinpoint Test	GO to Pinpoint Test F
The steering wheel switch(es) illumination is inoperative or always on	Refer to the Pinpoint Test	GO to Pinpoint Test G
All networked illumination is inoperative (non-networked illumination functions correctly)	Network communication concern BCM	Using a diagnostic scan tool, PERFORM a network test. If all modules pass the network test, Refer to BCM GUIDED ROUTINE TESTING . If all modules do not pass the network test, REFER to: Communications Network .
A single non-network illuminated switch or component is always on	Wiring Component	INSTALL a new illuminated switch or component.
The IPC illumination is inoperative or does not dim	Network communication concern IPC	Using a diagnostic scan tool, PERFORM a network test. If the IPC passes the network test, Refer to IPC GUIDED ROUTINE TESTING If the diagnostic scan tool responds with no communication with the IPC, REFER to: Communications Network .
The FCIM illumination is inoperative or does not dim	Network communication concern FCIM	Using a diagnostic scan tool, PERFORM a network test. If the FCIM passes the network test, Refer to FCIM GUIDED ROUTINE TESTING If the diagnostic scan tool responds with no communication with the FCIM, REFER to: Communications Network .
The hazard switch assembly illumination is inoperative or does not dim	Network communication concern FCIM	Using a diagnostic scan tool, PERFORM a network test. If the FCIM passes the network test, Refer to FCIM GUIDED ROUTINE TESTING If the diagnostic scan tool responds with no communication with the FCIM, REFER to: Communications Network .
The FDIM illumination is inoperative or does not dim	APIM FDIM	VERIFY the audio system can be operated from the FDIM. If the audio system responds normally to FDIM inputs, Refer to APIM GUIDED ROUTINE TESTING . If the FDIM illumination still does not function correctly after the repair, INSTALL a new FDIM. REFER to: Front Display Interface Module (FDIM) Vehicles With: Touchscreen Display . If the audio system does not respond normally to FDIM inputs, REFER to: Information and Entertainment System Vehicles With: AM/FM/CD/SYNC .
