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	REFER to: Communications Network .
All illumination (networked and non-networked) does not dim or increase brightness	Refer to the Pinpoint Test	GO to Pinpoint Test A
All networked illumination is inoperative (non-networked illumination functions correctly)	Network communication concern BCM	PERFORM the network test. If all modules pass the network test, Refer to BCM Hardware Testing .. If all modules do not pass the network test, REFER to: Communications Network .
All non-networked illumination sources are inoperative (networked illumination functions correctly)	Refer to the Pinpoint Test	GO to Pinpoint Test B
All non-networked illumination sources are always on (networked illumination functions correctly)	Refer to the Pinpoint Test	GO to Pinpoint Test D
One or more non-networked illumination source is inoperative	Refer to the Pinpoint Test	GO to Pinpoint Test C
A single non-network illuminated switch or component is always on	Illuminated switch or component	INSTALL a new illuminated switch or component.
Steering wheel switch(es) illumination without Active Front Steering is inoperative or always on	Refer to the Pinpoint Test	GO to Pinpoint Test G
Steering wheel switch(es) illumination with Active Front Steering is inoperative or always on	Refer to the Pinpoint Test	GO to Pinpoint Test H
The LH front window control switch illumination is inoperative or always on	Window control switch Wiring, terminals or connectors Fuse Module	Verify the operation of the power window. If the power window operates correctly, INSTALL a new window control switch. REFER to: Driver Door Window Control Switch . If the power window does not operate correctly, REFER to: Glass, Frames and Mechanisms .
The RH front window control switch illumination is inoperative or always on	Refer to the Pinpoint Test	GO to Pinpoint Test F
The LH front door lock/memory set switch illumination is inoperative or always on	Refer to the Pinpoint Test	GO to Pinpoint Test E
The RH front door lock switch illumination is inoperative or always on	Refer to the Pinpoint Test	GO to Pinpoint Test F
The LH rear window control switch illumination is inoperative or always on	Window control switch Wiring, terminals or connectors	Verify the operation of the power window. If the power window operates correctly, INSTALL a new window control switch. REFER to: Rear Door Window Control Switch . If the power window does not operate correctly, REFER to: Glass, Frames and Mechanisms .
The RH rear window control switch illumination is inoperative or always on	Window control switch Wiring, terminals or connectors	Verify the operation of the power window. If the power window operates correctly, INSTALL a new window control switch. REFER to: Rear Door Window Control Switch . If the power window does not operate correctly, REFER to: Glass, Frames and Mechanisms .
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, REFER to: Communications Network .
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 article for the procedure. 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 that the audio system can be operated from the FDIM. If the audio system responds normally to FDIM inputs, Refer to APIM Hardware Testing . If the FDIM illumination still does not function correctly after the repair, INSTALL a new FDIM. Refer to the appropriate article for the procedure. If the audio system does not respond normally to FDIM inputs, Refer to the appropriate article for the procedure.
