Symptom Chart: Instrument Panel and Interior Switches Illumination

Diagnostics in this service information assume a certain skill level and knowledge of Ford-specific diagnostic practices. For information about these practices, Refer to: Diagnostic Methods .

Symptom Chart

Condition	Possible Sources	Actions
A module does not respond to the diagnostic scan tool	Fuse Wiring, terminals or connectors Module	REFER to: Communications Network .
All dimmable illumination (networked and non-networked sources) does not dim or increase brightness	Refer to the Pinpoint Tests	GO to Pinpoint Test A
All dimmable non-networked illumination is inoperative (networked illumination functions correctly)	Refer to the Pinpoint Tests	GO to Pinpoint Test B
All dimmable non-networked illumination is always on (networked illumination functions correctly)	Refer to the Pinpoint Tests	GO to Pinpoint Test C
All dimmable networked illumination (non-networked illumination functions correctly) does not dim	Network communication concern BCM	Using a diagnostic scan tool, PERFORM a network test. If the diagnostic scan tool responds with no communication to any module on the MS-CAN, REFER to: Communications Network . If the diagnostic scan tool communicates with the modules on the MS-CAN, INSTALL a new BCM. REFER to: Body Control Module (BCM) .
The steering wheel switch(es) illumination is inoperative	Refer to the Pinpoint Tests	GO to Pinpoint Test D
One or more switch or component illumination is inoperative	Refer to the Pinpoint Tests	GO to Pinpoint Test E
The start/stop switch illumination is inoperative or always on (vehicles with push button start)	Refer to the Pinpoint Tests	GO to Pinpoint Test F
The window control switch illumination is inoperative	Wiring, terminals or connectors Window control switch	VERIFY the operation of the power windows. If the power windows operate correctly, INSTALL a new window control switch. REFER to: Front Door Window Control Switch . REFER to: Rear Door Window Control Switch . If the power windows do not operate correctly, REFER to: Glass, Frames and Mechanisms - Vehicles With: Front Manual Windows .
The IPC illumination is inoperative/does not dim	Network communication concern IPC	Using a diagnostic scan tool, PERFORM a 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/does not dim (without touchscreen display)	Refer to the Pinpoint Tests	GO to Pinpoint Test G
The FCIM illumination is inoperative/does not dim (with touchscreen display)	Network communication concern FCIM	VERIFY the operation of the audio system. If the audio system operates correctly, INSTALL a new FCIM. REFER to: Front Controls Interface Module (FCIM) - Vehicles With: AM/FM/CD/SYNC/Touchscreen Display. If the audio system does not operate correctly, REFER to: Information and Entertainment System - Vehicles With: AM/FM/CD/SYNC/Touchscreen Display.
The FCDIM illumination is inoperative/does not dim	Network communication concern FCDIM	VERIFY the operation of the audio system. If the audio system operates correctly, INSTALL a new FCDIM. REFER to: Front Control/Display Interface Module (FCDIM) - Vehicles With: AM/FM/CD/SYNC. REFER to: Front Control/Display Interface Module (FCDIM) - Vehicles With: AM/FM/CD/SYNC. If the audio system does not operate correctly, REFER to: Information and Entertainment System - Vehicles With: AM/FM/CD/SYNC. REFER to: Information and Entertainment System - Vehicles With: AM/FM/CD/SYNC.
The FDIM illumination is inoperative/does not dim	APIM FDIM	VERIFY the audio system can be operated from the FDIM. If the audio system operates correctly from 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: Front Display Interface Module (FDIM) - Vehicles With: AM/FM/CD/SYNC/Touchscreen Display. If the audio system does not operate correctly from FDIM inputs, REFER to: Information and Entertainment System - Vehicles With: AM/FM/CD/SYNC/Touchscreen Display.
The HVAC illumination is inoperative/does not dim (EMTC)	Refer to the Pinpoint Tests	GO to Pinpoint Test E
The HVAC illumination is inoperative/does not dim (EATC)	Network communication concern HVAC	Using a diagnostic scan tool, PERFORM a network test. If the HVAC module passes the network test, INSTALL a new HVAC module. REFER to: Heating, Ventilation and Air Conditioning (HVAC) Control Module . If the HVAC module does not pass the network test, REFER to: Communications Network .
