Pinpoint Test M : C1B14:11, C1B14:12

WARNING: This page is about a different car, the 2018 Ford F-550 Super Duty, 2018 Ford F-450 Super Duty, 2018 Ford F-350 Super Duty, and 2018 Ford F-250 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.

M1 CHECK THE FCIM (FRONT CONTROLS INTERFACE MODULE) DTCS
- Ignition ON.
- Using a diagnostic scan tool, perform FCIM self-test.
Is DTC C1B14:11 present?

Yes GO to M2

No GO to M5

M2 CHECK THE REFERENCE VOLTAGE CIRCUIT FOR A SHORT TO GROUND

Ignition OFF.

Disconnect FCIM C2402A .

Measure:

Is the resistance greater than 10, 000 ohms?

Yes

GO to M3

No	REPAIR the circuit.

M3 CHECK THE REFERENCE VOLTAGE CIRCUIT AND THE SIGNAL RETURN CIRCUIT FOR A SHORT TOGETHER

Ignition OFF.

Is the resistance greater than 200 ohms?

Yes

GO to M6

GO to M4

M4 CHECK THE A/C (AIR CONDITIONING) COMPONENTS

While measuring the resistance, disconnect the following components one at a time, in order. Stop disconnecting components if the measured resistance rises above 200 ohms.
- In-vehicle temperature and humidity sensor C2247
- Air distribution door actuator C236
- Temperature door actuator C2091
- Air inlet door actuator C289

Did the resistance rise above 200 ohms?

Yes

INSTALL a new sensor or actuator (the last one to be disconnected). Refer to the appropriate Climate Control Systems article for the procedure. When installing an actuator, CONNECT the actuator electrical connector before the FCIM. This allows the actuator to be calibrated when the FCIM is connected.

No	REPAIR the circuit.

M5 CHECK THE REFERENCE VOLTAGE CIRCUIT FOR A SHORT TO VOLTAGE

Ignition OFF.

Disconnect FCIM C2402A .

Measure:

With multifunction display

Is any voltage present?

Yes	REPAIR the circuit.

GO to M6

M6 CHECK FOR CORRECT FCIM (FRONT CONTROLS INTERFACE MODULE) OPERATION

Ignition OFF.

Disconnect and inspect all 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 all 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 a loose or corroded connector. ADDRESS the root cause of any connector or pin issues.
