Pinpoint Test N: The Front Display Interface Module (FDIM) Is Completely Inoperative - Vehicles Without Navigation
Refer to Wiring Diagram Set 130 (Fusion/Milan/MKZ, Fusion Hybrid, Milan Hybrid, MKZ Hybrid), Audio System/Navigation for schematic and connector information. Diagrams By Number
Normal Operation
The Front Display Interface Module (FDIM) receives power at all times. The ignition switch position message is broadcast to the FDIM by the Smart Junction Box (SJB) via the Medium Speed Controller Area Network (MS-CAN).
Information from the audio system, the climate control system, the SYNC(R) system, and the compass heading are shown on the FDIM display screen. If only one of these displays has a concern, GO to Pinpoint Test K. Pinpoint Test K: An Individual Front Display Interface Module (FDIM) Display Is Inoperative - Vehicles Without Navigation
This pinpoint test is intended to diagnose the following:
- Communication network concern
- FDIM
PINPOINT TEST N: THE FDIM IS COMPLETELY INOPERATIVE - VEHICLES WITHOUT NAVIGATION
-------------------------------------------------
N1 CHECK FOR SCAN TOOL COMMUNICATION WITH THE FDIM
- Ignition ON.
- Carry out the network test using the scan tool.
- Does the scan tool communicate with the FDIM?
Yes
GO to N2.
No
REFER to Module Communications Network Testing and Inspection.
-------------------------------------------------
N2 CHECK FOR CORRECT FDIM OPERATION
- Ignition OFF.
- Disconnect the FDIM connector.
- Check for:
- corrosion
- damaged pins
- pushed-out pins
- Connect the FDIM connector and make sure it seats correctly.
- Operate the system and determine if the concern is still present.
- Is the concern still present?
Yes
INSTALL a new FDIM. REFER to Front Display Interface Module (FDIM) - Fusion, Milan Front Display Interface Module (FDIM) or Front Display Interface Module (FDIM) - MKZ Front Display Interface Module (FDIM). TEST the system for normal operation.
No
The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.
