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
A module does not respond to the diagnostic scan tool	Fuse Wiring, terminals or connectors Module
All networked illumination is inoperative (non-networked illumination functions correctly)	Network communication concern BCM	PERFORM a network test. If all modules pass the network test, INSTALL a new BCM. Refer to the appropriate Removal and Installation procedure in MULTIFUNCTION ELECTRONIC MODULES .. If all modules do not pass the network test,
The illumination intensity of all networked and non-networked backlighting cannot be increased or decreased	Refer to the Pinpoint Test	GO to Pinpoint Test A
All non-networked illumination sources are inoperative; networked illumination functions normally	Refer to the Pinpoint Test	GO to Pinpoint Test B
All non-networked illumination sources are always on; networked illumination functions normally	Refer to the Pinpoint Test	GO to Pinpoint Test C
One or more non-networked illumination source is inoperative	Refer to the Pinpoint Test	GO to Pinpoint Test D
A single non-network illuminated switch or component is always on	Illuminated switch or component	INSTALL a new illuminated switch or component.
The LHF door lock control switch illumination is inoperative or always on	Refer to the Pinpoint Test	GO to Pinpoint Test E
The RHF door lock control switch illumination is inoperative or always on	Refer to the Pinpoint Test	GO to Pinpoint Test F
The LHF window control switch illumination is inoperative or always on	Refer to the Pinpoint Test	GO to Pinpoint Test E
The RHF window control switch illumination is inoperative or always on	Refer to the Pinpoint Test	GO to Pinpoint Test F
The LHR door switch illumination is inoperative or always on	Refer to the Pinpoint Test	GO to Pinpoint Test G
The RHR door switch illumination is inoperative or always on	Refer to the Pinpoint Test	GO to Pinpoint Test H
Steering wheel switch(es) illumination is inoperative or always on	Refer to the Pinpoint Test	GO to Pinpoint Test I
The IPC illumination is inoperative or does not dim	Network communication concern IPC	PERFORM the network test. If the IPC passes the network test, INSTALL a new IPC. REFER to: Instrument Panel Cluster (IPC) . If the diagnostic scan tool responds with no communication with the IPC.
The FCIM illumination is inoperative or does not dim	Network communication concern FCIM	PERFORM the network test. If the FCIM passes the network test, INSTALL a new FCIM. Refer to the appropriate Removal and Installation procedure in REMOVAL AND INSTALLATION If the diagnostic scan tool responds with no communication with the FCIM,
The FDIM illumination does not dim	Network communication concern FDIM	PERFORM a network test. If the scan tool does not communicate with the APIM, If the scan tool communicates with the APIM, refer to FDIM GUIDED ROUTINE TESTING
The RACM illumination is inoperative or will not dim.	Network concerns RACM	PERFORM the network test. If the RACM passes the network test, INSTALL a new RACM. [No proc available yet] If the diagnostic scan tool responds with no communication with the RACM.
