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 |
