Pinpoint Test I: The FCIM (Front Controls Interface Module) Illumination Is Inoperative/Does Not Dim (Base/Premium)

WARNING: This page is about a different car, the 2014 Ford Focus. However, it is still accessible from the selected car via links, so may be relevant.

I1 PERFORM A NETWORK TEST
- Ignition ON.
- Using a diagnostic scan tool, perform a network test.
Does the FCDIM pass the network test .
1. Yes : GO to I2
2. No : REFER to: COMMUNICATIONS NETWORK .
I2 CHECK THE FCDIM (FRONT CONTROL/DISPLAY INTERFACE MODULE) CONTINUOUS MEMORY DIAGNOSTIC TROUBLE CODES (CMDTC'S)
- Using a diagnostic scan tool, check the FCDIM Continuous Memory Diagnostic Trouble Codes (CMDTC'S).
Are any Diagnostic Trouble Codes (DTC's) present?
1. Yes : If equipped with Sync®
  REFER to: INFORMATION AND ENTERTAINMENT SYSTEM .
  
  If not equipped with Sync®
  
  REFER to: INFORMATION AND ENTERTAINMENT SYSTEM .
2. No : GO to I3

I3 CHECK THE VOLTAGE TO THE FCIM (FRONT CONTROLS INTERFACE MODULE)

Ignition OFF.
Disconnect: FCIM C2402 .
Ignition ON.

Measure:

Positive Lead	Measurement/Action	Negative Lead
C2402-8		Ground

Is the voltage greater then 11 volts?

Yes : GO to I4
No : CHECK BCM fuse 79 (15A). If the fuse is OK, REPAIR the circuit for an open. If the fuse is not OK, REFER to the OEM WIRING DIAGRAMS -- EXCEPT ELECTRIC to identify the possible cause of the circuit short.

I4 CHECK FOR GROUND TO THE FCIM (FRONT CONTROLS INTERFACE MODULE)

Measure:

Positive Lead	Measurement/Action	Negative Lead
C2402-8		C2402-5

Is the voltage greater then 11 volts?

Yes : GO to I5
No : REPAIR circuit GD133.

I5 CHECK THE LIN (LOCAL INTERCONNECT NETWORK) CIRCUIT FOR A SHORT TO VOLTAGE

Ignition OFF.
Disconnect: FCDIM C2123 .
Ignition ON.

Measure:

Positive Lead	Measurement/Action	Negative Lead
C2402-7		Ground

Is any voltage present?

Yes : REPAIR the circuit.
No : GO to I6

I6 CHECK THE LIN (LOCAL INTERCONNECT NETWORK) FOR A SHORT TO GROUND

Ignition OFF.

Measure:

Positive Lead	Measurement/Action	Negative Lead
C2402-7		Ground

Is the resistance greater than 10, 000 ohms?

Yes : GO to I7
No : REPAIR the circuit.

I7 CHECK THE LIN (LOCAL INTERCONNECT NETWORK) FOR AN OPEN

Measure:

Positive Lead	Measurement/Action	Negative Lead
C2402-7		C2123-8

Is the resistance less than 3 ohms?

Yes : GO to I8
No : REPAIR the circuit.

I8 CHECK FOR CORRECT FCIM (FRONT CONTROLS INTERFACE MODULE) OPERATION
- Ignition OFF.
- Disconnect and inspect all the FCIM 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 FCIM connectors. Make sure they seat and latch correctly.
- Operate the system and determine if the concern is still present.
Is the concern still present?
1. Yes : CHECK OASIS for any applicable Technical Service Bulletins (TSBs). If a TSB exists for this concern, DISCONTINUE this test and FOLLOW the TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new FCIM . For vehicle equipped with Sync®
  REFER to: FRONT CONTROLS INTERFACE MODULE (FCIM) .
  
  For vehicle not equipped with Sync® REFER to: FRONT CONTROLS INTERFACE MODULE (FCIM) .
2. 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.
