PINPOINT TEST Y : The FCIM Does Not Respond To The Scan Tool

NOTE: Failure to disconnect the battery when instructed will result in false resistance readings. REFER to Battery, Mounting and Cables

Y1 CHECK THE FCIM VOLTAGE SUPPLY CIRCUIT FOR AN OPEN

Measure:

Positive Lead	Measurement / Action	Negative Lead
C2402-1	Courtesy of FORD MOTOR COMPANY	Ground

Is the voltage greater than 11 volts?

Yes	GO to Y2.
No	VERIFY the BCM fuse 9 (10A) is OK. If OK, REPAIR the circuit. If not OK, REFER to the OEM ELECTRICAL WIRING DIAGRAM INTRODUCTION to identify the possible causes of the circuit short.

Y2 CHECK THE FCIM GROUND CIRCUIT FOR AN OPEN

Measure:

Positive Lead	Measurement / Action	Negative Lead
C2402-6	Courtesy of FORD MOTOR COMPANY	Ground

Is the resistance less than 3 ohms?

Yes	GO to Y3.
No	REPAIR the circuit.

Y3 CHECK THE I-CAN CIRCUITS BETWEEN THE FCIM AND THE IPC FOR AN OPEN

Measure:

Positive Lead	Measurement / Action	Negative Lead
C2402-2	Courtesy of FORD MOTOR COMPANY	C220-25
C2402-3	Courtesy of FORD MOTOR COMPANY	C220-26

Are the resistances less than 3 ohms?

Yes	CONNECT the negative battery cable. GO to Y4.
No	REPAIR the circuit in question.

Y4 CHECK FOR CORRECT FCIM OPERATION

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

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

Is the concern still present?

Yes	CHECK OASIS for any applicable TSBs. If a TSB exists for this concern, discontinue this test and follow TSB instructions. If no TSBs address this concern, INSTALL a new FCIM. REFER to Information and Entertainment Systems Premium (Premium), REFER to Information and Entertainment Systems Premium Plus (Premium Plus), or REFER to Information and Entertainment Systems Sony Sound (Sony ® Sound).
No	The system is operating correctly at this time. Concern may have been caused by a loose or corroded connector.
