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 networked illumination is inoperative (non-networked illumination functions correctly) Network communication concern
BCM
PERFORM a network test. REFER to: Communications Network
If all modules pass the network test, Refer to BCM Guided Routine . .
If all modules do not pass the network test, REFER to: Communications Network
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. 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, Refer to FCIM GUIDED ROUTINE .
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 Guided Routine . . If the FDIM illumination still does not function correctly after the repair, INSTALL a new FDIM. or
If the audio system does not respond normally to FDIM inputs, or
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. REFER to: Communications Network
