Escape 4WD L4-2.5L Hybrid (2009)
-
Are the resistances less than 5 ohms?
Yes
CONNECT the negative battery cable. GO to M4.
No
REPAIR the circuit in question. CONNECT the negative battery cable. CLEAR the DTCs. REPEAT the network test with the scan tool.
-------------------------------------------------
M4 CHECK FOR CORRECT SDARS MODULE OPERATION
-
Disconnect all the SDARS module connectors.
-
Check for:
-
corrosion
-
damaged pins
-
pushed-out pins
-
Connect all the SDARS module connectors and make sure they seat correctly.
-
Operate the system and verify the concern is still present.
-
Is the concern still present?
Yes
INSTALL a new SDARS module. CLEAR the DTCs. REPEAT the network test with the scan tool.
No
The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. CLEAR the DTCs. REPEAT the
network test with the scan tool.

Pinpoint Test N: The Front Display Interface Module (FDIM) Does Not Respond To The Scan Tool
Refer to Wiring Diagram Set 14 (Escape/Mariner, Escape Hybrid/Mariner Hybrid), Module Communications Network for schematic and connector
information. See: Diagrams/Electrical Diagrams/Diagrams By Number
Refer to Wiring Diagram Set 130 (Escape/Mariner, Escape Hybrid/Mariner Hybrid), Audio System/Navigation for schematic and connector information.

Normal Operation
The Front Display Interface Module (FDIM) communicates with the scan tool through the Medium Speed Controller Area Network (MS-CAN). Circuits
VDB06 (GY/OG) (MS-CAN +) and VDB07 (VT/OG) (MS-CAN -) provide the network connection to the front display interface module. Voltage to the
FDIM is provided by circuit SBP14 (BN/RD). Ground is provided by circuit GD114 (BK/BU).
This pinpoint test is intended to diagnose the following:
-
Fuse
-
Wiring, terminals or connectors
-
FDIM
