Pinpoint Test D : The FCDIM (Front Control/Display Interface Module) Does Not Respond To The Scan Tool

WARNING: This page is about a different car, the 2018 Ford Focus. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Failure to disconnect the battery when instructed will result in false resistance readings.

D1 CHECK THE FCDIM (FRONT CONTROL/DISPLAY INTERFACE MODULE) VOLTAGE SUPPLY CIRCUIT FOR AN OPEN

Ignition OFF.

Disconnect: FCDIM.

Ignition ON.

Measure:

Positive Lead	Measurement / Action	Negative Lead

Is the voltage greater than 11 volts?

Yes

GO to D2

No	VERIFY the BCM fuse 67 (7.5A) is OK. If OK, REPAIR the circuit. If not OK, REFER to the OEM ELECTRICAL WIRING DIAGRAM INTRODUCTION (EXCEPT ELECTRIC) to identify the possible causes of the circuit short.

D2 CHECK THE FCDIM (FRONT CONTROL/DISPLAY INTERFACE MODULE) GROUND CIRCUIT FOR AN OPEN

Ignition OFF.

Measure:

Positive Lead	Measurement / Action	Negative Lead

Are the resistances less than 3 ohms?

Yes

GO to D3

No	REPAIR the circuit in question.

D3 CHECK THE I-CAN (INFOTAINMENT COMMUNICATION NETWORK) CIRCUITS BETWEEN THE FCDIM (FRONT CONTROL/DISPLAY INTERFACE MODULE) AND THE IPC (INSTRUMENT PANEL CLUSTER) FOR AN OPEN

Disconnect: IPC.

Measure:

Positive Lead	Measurement / Action	Negative Lead

Are the resistances less than 3 ohms?

Yes

GO to D4

No	REPAIR the circuit in question.

D4 CHECK FOR CORRECT FCDIM (FRONT CONTROL/DISPLAY INTERFACE MODULE) OPERATION

Ignition OFF.

Disconnect and inspect the FCDIM connector and related in-line connectors.

Repair:
- corrosion (install new connector or terminals - clean module pins)
- damaged or bent pins - install new terminals/pins
- pushed-out pins - install new pins as necessary

Reconnect the FCDIM connector and related in-line connectors. Make sure they seat and latch correctly.

Operate the system and determine if the concern is still present.

Is the concern still present?

Yes

CHECK OASIS for any applicable Technical Service Bulletins (TSBs). If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new FCDIM. If equipped with AM/FM/CD/SYNC, REFER to: Front Control/Display Interface Module (FCDIM) .

No	The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
