Is the resistance between 108 and 132 ohms?

Yes

GO to N3

GO to N2

N2 CHECK THE MS-CAN (MEDIUM SPEED-CONTROLLER AREA NETWORK) CIRCUITS BETWEEN THE FCIM (FRONT CONTROLS INTERFACE MODULE) AND THE GWM (GATEWAY MODULE A) FOR AN OPEN

Disconnect FCIM C2402A .

Measure:

Positive Lead	Measurement / Action	Negative Lead

Are the resistances less than 3 ohms?

Yes

GO to N5

No	REPAIR the circuit in question.

N3 CHECK THE FCIM (FRONT CONTROLS INTERFACE MODULE) VOLTAGE SUPPLY CIRCUIT FOR AN OPEN

Connect negative battery cable.

Ignition ON.

Measure:

Positive Lead	Measurement / Action	Negative Lead

Is the voltage greater than 11 volts?

Yes

GO to N4

No	VERIFY the BCM fuse 12 (7.5A) is OK. If OK, REPAIR the circuit. If not OK, REFER to OEM Electrical Wiring Diagram Introduction (Except Hybrid) to identify the possible causes of the circuit short.

N4 CHECK THE FCIM (FRONT CONTROLS INTERFACE MODULE) GROUND CIRCUIT FOR AN OPEN

Ignition OFF.

Disconnect negative battery cable.

Measure:

Positive Lead	Measurement / Action	Negative Lead
C2402A-1	Courtesy of FORD MOTOR COMPANY	Ground

Is the resistance less than 3 ohms?

Yes	CONNECT negative battery cable. GO to N5

No	REPAIR the circuit.

N5 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?

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, Refer to FCIM Hardware Testing .

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.
