Symptom Chart: Instrument Panel and Interior Switches Illumination
Diagnostics in this article assume a certain skill level and knowledge of Ford-specific diagnostic practices. For information about these practices, REFER to: Diagnostic Methods .
| 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 non-networked illumination is inoperative (networked illumination functions correctly) | Refer to the Pinpoint Test | GO to Pinpoint Test A |
| All dimmable non-networked illumination is always on (networked illumination functions correctly) | Refer to the Pinpoint Test | GO to Pinpoint Test B |
| All dimmable illumination (networked and non-networked sources) does not dim or increase brightness | Refer to the Pinpoint Test | GO to Pinpoint Test C |
| The steering wheel switch(es) illumination is inoperative | Refer to the Pinpoint Test | GO to Pinpoint Test D |
| One Or More Dimmable Non-Networked Illumination Source Is Inoperative | Refer to the Pinpoint Test | GO to Pinpoint Test E |
| The RH front, RH rear or LH rear window control switch illumination is inoperative or always on (One-Touch Up and Down Front Windows) | Refer to the Pinpoint Test | GO to Pinpoint Test F |
| The LH front window control switch illumination is inoperative or always on (One-Touch Up and Down Front Windows) | Window control switch | VERIFY the operation of the power windows. If the power windows operate correctly, INSTALL a new LH front window control switch. If the power windows do not operate correctly, REFER to: Glass, Frames and Mechanisms - Vehicles With: One-Touch Open and Close Front Windows . |
| The window control switch illumination is inoperative or always on (One-Touch Down Driver Window) | 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. If the power windows do not operate correctly, REFER to: Glass, Frames and Mechanisms - Vehicles With: One-Touch Open Driver Window . |
| The FCIM illumination is inoperative/does not dim (with 4.2-inch [107mm] display) | Refer to the Pinpoint Test | GO to Pinpoint Test G |
| The FCIM illumination is inoperative/does not dim (with 6.5-inch [165mm] touchscreen display) | Network communication concern FCIM |
VERIFY the operation of the audio system. If the audio system operates correctly, INSTALL a new FCIM. If the audio system does not operate correctly, REFER to: Information and Entertainment System . |
| The ACM illumination is inoperative/does not dim (without 6.5-inch [165mm] touchscreen display and without 4.2-inch [107mm] display) | Refer to the Pinpoint Test | GO to Pinpoint Test E |
| 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. If the audio system does not operate correctly, REFER to: Information and Entertainment System With: AM/FM/CD . REFER to: Information and Entertainment System With: AM/FM/CD/SYNC . |
| The FDIM illumination is inoperative/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, CARRY OUT the APIM Hardware Test. Refer to: APIM Hardware Testing . If the FDIM illumination still does not function correctly after the repair, INSTALL a new FDIM. If the audio system does not respond normally to FDIM inputs, REFER to: Information and Entertainment System . |
| The IPC illumination is inoperative/does not dim | Network communication concern IPC |
Using a diagnostic scan tool, CARRY OUT a network test. If the IPC passes the network test, Refer to: IPC Hardware Testing . If the diagnostic scan tool responds with no communication with the IPC, REFER to: Communications Network . |
| The HVAC module illumination is inoperative/does not dim (with DATC) | Network communication concern HVAC module |
Using a diagnostic scan tool, CARRY OUT a network test. If the HVAC module passes the network test, INSTALL a new HVAC module. REFER to: Climate Control Assembly . If the diagnostic scan tool responds with no communication with the HVAC module, REFER to: Communications Network . |
| The HVAC module illumination is inoperative/does not dim (with EATC) | Refer to the Pinpoint Test | GO to Pinpoint Test E |
